phpMyAdmin 2.4.0-rc2 Documentation
* Sourceforge phpMyAdmin project page [ http://www.phpmyadmin.net/
]
* Local documents:
+ Version history: ChangeLog
+ General notes: README
+ License: LICENSE
* Documentation version: $Id: Documentation.html,v 1.391 2003/02/04
11:01:24 lem9 Exp $
Requirements
* PHP3 or PHP4: phpMyAdmin widely uses the 'str_replace()' php
function that was added in PHP 3.0.6, but was buggy up until
PHP 3.0.8. Then you should not run this script with PHP3 < 3.0.8.
PHP also needs to be compiled with MySQL support;
* MySQL (tested with 3.21.x, 3.22.x, 3.23.x and 4.0.x);
Note: Because of a major change in the definition syntax of string
field types, this version of phpMyAdmin probably won't work
correctly with MySQL >= 4.1.0!
* a web-browser (doh!).
Introduction
phpMyAdmin can manage a whole MySQL-server (needs a super-user) but
also a single database. To accomplish the latter you'll need a
properly set up MySQL-user who can read/write only the desired
database. It's up to you to look up the appropriate part in the MySQL
manual. Currently phpMyAdmin can:
* create and drop databases
* create, copy, drop, rename and alter tables
* do table maintenance
* delete, edit and add fields
* execute any SQL-statement, even batch-queries
* manage keys on fields
* load text files into tables
* create (*) and read dumps of tables
* export (*) data to CSV, XML and Latex formats
* administer multiple servers
* check referential integrity
* using Query-by-example (QBE), create complex queries automatically
connecting required tables
* create PDF graphics of your Database layout
* search globally in a database or a subset of it
* communicate in 43 different languages
(*) phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
dumps and CSV exports if you use PHP4 >= 4.0.4 with Zlib support
(--with-zlib) and/or Bzip2 support (--with-bz2).
Installation
NOTE: phpMyAdmin does not apply any special security methods to the
MySQL database server. It is still the sysadmin's job to grant
permissions on the MySQL databases properly. phpMyAdmin's "Users" page
can be used for this.
Warning for Mac users:if you are on a MacOS version before OS X,
Stuffit unstuffs with Mac formats.
So you'll have to resave as in Bbedit to unix style ALL phpMyAdmin
scripts before uploading them to your server, as PHP seems not to like
Mac-style end of lines character ("\r").
Documentation warning: when you see in this document a .php3 file
extension, please transpose to .php if you are using a kit with files
having this extension.
Quick Install:
1. Choose and download a distribution kit with the files having the
extension (.php3 or .php) depending on the way your web/PHP server
interprets those extensions.
2. Untar or unzip the distribution (be sure to unzip the
subdirectories): tar xzvf phpMyAdmin_x.x.x.tar.gz in your
webserver's document root. If you don't have direct access to your
document root, put the files in a directory on your local machine,
and, after step 3, transfer the directory on your web server
using, for example, ftp.
3. Open the file config.inc.php3 in your favourite editor and change
the values for host, user, password and authentication mode to fit
your environment. Also insert the correct value for
$cfg['PmaAbsoluteUri']. Have a look at Configuration section for
an explanation of all values.
4. It is recommended that you protect the directory in which you
installed phpMyAdmin (unless it's on a closed intranet, or you
wish to use http or cookie authentication), for example with
HTTP-AUTH (in a .htaccess file). See the FAQ section for
additional information.
5. Open the file <www.your-host.com>/<your-install-dir>/index.php3 in
your browser. phpMyAdmin should now display a welcome screen and
your databases, or a login dialog if using http or cookie
authentication mode.
Upgrading from an older version:
* Please do not copy your older config.inc.php3 over the new one: it
may offer new configuration variables, and the new version may
depend on these for normal behavior. It is suggested instead to
insert your site values in the new one.
Using authentication modes:
* Http and cookie authentication modes are recommended in a
multi-user environment where you want to give users access to
their own database and don't want them to play around with others.
Nevertheless be aware that MS Internet Explorer seems to be really
buggy about cookies, at least till version 6. And php 4.1.1 is
also a bit buggy in this area!
Even in a single-user environment, you might prefer to use http or
cookie mode so that your user/password pair are not in clear in
the configuration file.
* Http and cookie authentication modes are more secure: the MySQL
password does not need to be set in the phpMyAdmin configuration
file (except for the "controluser" -see the Configuration
section).
However, keep in mind that the password travels in plain text,
unless you are using the https protocol.
In cookie mode, we send the password in a temporary cookie, so
most browsers should not store the password in their cookie file.
* For 'http' and 'cookie' modes, phpMyAdmin needs a controluser that
has only the SELECT privilege on the mysql.user (all columns
except "Password"), mysql.db (all columns) & mysql.tables_priv
(all columns except "Grantor" & "Timestamp") tables.
You must specify the details for the controluser in the
config.inc.php3 file under the $cfg['Servers'][$i]['controluser']&
$cfg['Servers'][$i]['controlpass'] settings.
This example assumes you want to use pma as the controluser and
pmapass as the controlpass, but this is only an example: use
something else in your file:
GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT SELECT (Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv, Create_priv,
Drop_priv, Reload_priv, Shutdown_priv, Process_priv, File_priv,
Grant_priv, References_priv, Index_priv, Alter_priv)
ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
ON mysql.tables_priv TO 'pma'@'localhost';
... and if you want to use the many new relation and bookmark
features:
GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db> TO 'pma'@'localhost';
(this of course requires you to have a special DB for phpMyAdmin,
the contents will be explained later)
* Then each of the true users should be granted a set of privileges
on a set of particular databases. Normally you shouldn't give
global privileges to an ordinary user, unless you understand the
impact of those privileges (for example, you are creating a
superuser).
For example, to grant the user real_user with all privileges on
the database user_base:
GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost
IDENTIFIED BY 'real_password';
What the user may now do is controlled entirely by the MySQL user
management system.
With http or cookie auth mode, you don't need to fill the
user/password fields inside the $cfg['Servers'] array.
'http' authentication mode:
* Was called 'advanced' in versions before 2.2.3.
* Introduced in 1.3.0, it uses Basic HTTP authentication method and
allows you to login as any valid MySQL user.
* Is only supported with PHP running as an Apache module, not with
cgi.
'cookie' authentication mode:
* You can use this method as a replacement for the http
authentication (for example, if you're running IIS).
* Obviously, the user must enable cookies in the browser.
* With this mode, the use can truly logout of phpMyAdmin and login
back with the same username.
'config' authentication mode:
* This mode is the less secure one because it requires you to fill
the $cfg['Servers'][$i]['user'] and
$cfg['Servers'][$i]['password'] fields.
But you don't need to setup a "controluser" here: using the
$cfg['Servers'][$i]['only_db'] might be enough.
* In the ISP FAQ section, there is an entry explaining how to
protect your configuration file.
* For additional security in this mode, you may wish to consider the
Host authentication $cfg['Servers'][$i]['AllowDeny']['order'] and
$cfg['Servers'][$i]['AllowDeny']['rules'] configuration
directives.
Configuration
Warning for Mac users: php seems not to like Mac end of lines
character ("\r"). So ensure you choose the option that allows to use
the *nix end of line character ("\n") in your text editor before
registering a script you have modified.
All configurable data is placed in config.inc.php3.
$cfg['PmaAbsoluteUri'] string
Sets here the complete url (with full path) to your phpMyAdmin
version. E.g.
http://www.your_web.net/path_to_your_phpMyAdmin_directory/.
phpMyAdmin needs this setting, because of requirements of the
HTTP protocol, explained in RFC2616, section 14.30.
Don't forget the slash at the end of your url. The url must
contain characters that are valid for a url, and on some
servers, the path is case-sensitive.
Starting with version 2.3.0, you can try to leave this
parameter empty, because the program tries to auto-detect its
proper value. Additional details are in the configuration file.
Alternatively, this setting can be dynamically completed. For
example, you can try to use such a kind of code:
$cfg['PmaAbsoluteUri'] = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://'
. $_SERVER['HTTP_HOST']
. (!empty($_SERVER['SERVER_PORT']) ? ':' . $_SERVER['SERVER_PORT'] : '')
. substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'], '/')+1);
or
$cfg['PmaAbsoluteUri'] = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://'
. $_SERVER['SERVER_NAME']
. (!empty($_SERVER['SERVER_PORT']) ? ':' . $_SERVER['SERVER_PORT'] : '')
. substr($_SERVER['SCRIPT_NAME'], 0, strrpos($_SERVER['SCRIPT_NAME'], '/')+1);
Please note that the $_SERVER array doesn't exist in
PHP < 4.1.0. Try to replace $_SERVER by $HTTP_SERVER_VARS or
$GLOBALS in this case.
$cfg['PmaAbsoluteUri_DisableWarning'] boolean
By default, when you leave $cfg['PmaAbsoluteUri'] empty, and
the system detects your absolute URI automatically, we display
a warning to remind you. If you have tested the automatic
detection, and it works perfectly for your setup, then you can
set this variable to squelch the warning.
$cfg['PmaNoRelation_DisableWarning'] boolean
Starting with version 2.3.0 phpMyAdmin offers a lot of features
to work with master / foreign - tables (see
$cfg['Servers'][$i]['pmadb']).
If you tried to set this up and it does not work for you, have
a look on the "Structure" page of one database where you would
like to use it. You will find a link that will analyze why
those features have been disabled.
If you do not want to use those features set this variable to
TRUE to stop this message from appearing.
$cfg['Servers'] array
Since version 1.4.2, phpMyAdmin supports the administration of
multiple MySQL servers. Therefore, a $cfg['Servers']-array has
been added which contains the login information for the
different servers. The first $cfg['Servers'][$i]['host']
contains the hostname of the first server, the second
$cfg['Servers'][$i]['host'] the hostname of the second server,
etc. If you have only one server to administer, simply leave
free the hostname of the other $cfg['Server']-entries.
$cfg['Servers'][$i]['host'] string
The hostname of your $i-th MySQL-server. E.g. localhost.
$cfg['Servers'][$i]['port'] string
The port-number of your $i-th MySQL-server. Default is 3306
(leave blank).
$cfg['Servers'][$i]['socket'] string
The path to the socket to use. Leave blank for default.
To use the socket feature you must run php 3.0.10 or more.
$cfg['Servers'][$i]['connect_type'] string
What type connection to use with the MySQL server. Your options
are 'socket' & 'tcp'. It defaults to 'tcp' as that is nearly
guarenteed to be available on all MySQL servers, while sockets
are not supported on some platforms.
To use the socket mode, your MySQL server must be on the same
machine as the Web server.
$cfg['Servers'][$i]['compress'] boolean
Wheather to use a compressed protocol for the MySQL server
connection or not (experimental).
This feature requires PHP >= 4.3.0.
$cfg['Servers'][$i]['controluser'] string
$cfg['Servers'][$i]['controlpass'] string
When using http or cookie authentication modes (or 'config'
authentication mode since phpMyAdmin 2.2.1), you need to supply
the details of a MySQL account that has SELECT privilege on the
mysql.user (all columns except "Password"), mysql.db (all
columns) & mysql.tables_priv (all columns except "Grantor" &
"Timestamp") tables. This account is used to check what
databases the user will see at login.
Please see the install section on "Using http authentication"
for more information.
Note that if you try login to phpMyAdmin with this
"controluser", you could get some errors, depending the exact
privileges you gave to the "controluser". phpMyAdmin does not
support a direct login with the "controluser".
In versions before 2.2.5, those were called "stduser/stdpass".
$cfg['Servers'][$i]['auth_type'] string ['http'|'cookie'|'config']
Whether config or cookie or http authentication should be used
for this server.
+ 'config' authentication ($auth_type = 'config') is the plain
old way: username and password are stored in config.inc.php3.
+ 'cookie' authentication mode ($auth_type = 'cookie') as
introduced in 2.2.3 allows you to log in as any valid MySQL
user with the help of... cookies. Log name and password are
stored in cookies during the session and password is deleted
when it ends.
+ 'http' authentication (was called 'advanced' in older
versions) ($auth_type = 'http') as introduced in 1.3.0 allows
you to log in as any valid MySQL user via HTTP-Auth.
Please see the install section on "Using authentication modes"
for more information.
$cfg['Servers'][$i]['user'] string
$cfg['Servers'][$i]['password'] string
The user/password-pair which phpMyAdmin will use to connect to
this MySQL-server. This user/password pair is not needed when
http or cookie authentication is used, and should be empty.
$cfg['Servers'][$i]['only_db'] string or array
If set to a(an array of) database name(s), only this(these)
database(s) will be shown to the user. Since phpMyAdmin 2.2.1,
this/these database(s) name(s) may contain MySQL wilcards
characters ("_" and "%"): if you want to use literal instances
of these characters, escape them (ie use 'my\_db' and not
'my_db').
This setting is an efficient way to lower the server charge
since the latter does not need to send MySQL requests to build
the available database list. But it does not replace the
privileges rules of the MySQL database server. If set, it just
means only these databases will be displayed but not at all
other databases can't be used.
$cfg['Servers'][$i]['verbose'] string
Only useful when using phpMyAdmin with multiple server entries.
If set, this string will be displayed instead of the hostname
in the pulldown menu on the main page. This can be useful if
you want to show only certain databases on your system, for
example.
$cfg['Servers'][$i]['pmadb'] string
Starting with version 2.3.0 phpMyAdmin offers a lot of features
to work with master / foreign - tables. To use those as well as
the bookmark feature you need special tables with a predefined
structure, which we explain below.
If you are the only user of this phpMyAdmin installation, you
can use your current database to store those special tables; in
this case, just put your current database name in
$cfg['Servers'][$i]['pmadb'].
If you are setting up a multi-user phpMyAdmin installation, you
will need to create a new db and setup special privileges, so,
as superuser:
+ create a new database for phpmyadmin:
CREATE DATABASE phpmyadmin;
Note that "controluser" must have SELECT, INSERT, UPDATE and
DELETE privileges on this database. Here is a query to set up
those privileges (using "phpmyadmin" as the database name,
and "pma" as the controluser):
GRANT SELECT,INSERT,UPDATE,DELETE ON phpmyadmin.* to
'pma'@'localhost';
do not give any other user rights on this database.
+ enter the databasename in $cfg['Servers'][$i]['pmadb']
$cfg['Servers'][$i]['bookmarktable'] string
Since release 2.2.0 phpMyAdmin allows to bookmark queries. This
can be useful for queries you often run.
To allow the usage of this functionality you have to:
+ set up "pmadb" as described above
+ within this database create a table following this scheme:
CREATE TABLE `PMA_bookmark` (
id int(11) DEFAULT '0' NOT NULL auto_increment,
dbase varchar(255) NOT NULL,
user varchar(255) NOT NULL,
label varchar(255) NOT NULL,
query text NOT NULL,
PRIMARY KEY (id)
) TYPE=MyISAM COMMENT='Bookmarks';
+ enter the tablename in $cfg['Servers'][$i]['bookmarktable']
$cfg['Servers'][$i]['relation'] string
Since release 2.2.4 you can describe, in a special 'relation'
table, which field is a key in another table (a foreign key).
phpMyAdmin currently uses this to
+ make clickable, when you browse the master table, the data
values that point to the foreign table;
+ display in an optional tooltip the "display field" when
browsing the master table, if you move the mouse to a column
containing a foreign key (use also the 'table_info' table);
+ display links on the table properties page, to check
referential integrity (display missing foreign keys) for each
described key;
+ in query-by-example, create automatic joins (see an example
in the FAQ, section "Using phpMyAdmin");
+ enable you to get a PDF schema of your database (also uses
the table_coords table).
The keys can be numeric or character.
To allow the usage of this functionality the superuser has to:
+ set up "pmadb" as described above
+ within this database create a table following this scheme:
CREATE TABLE `PMA_relation` (
`master_db` varchar(64) NOT NULL default '',
`master_table` varchar(64) NOT NULL default '',
`master_field` varchar(64) NOT NULL default '',
`foreign_db` varchar(64) NOT NULL default '',
`foreign_table` varchar(64) NOT NULL default '',
`foreign_field` varchar(64) NOT NULL default '',
PRIMARY KEY (`master_db`, `master_table`,
`master_field`),
KEY foreign_field (foreign_db, foreign_table)
) TYPE=MyISAM COMMENT='Relation table';
+ put the relation table name in
$cfg['Servers'][$i]['relation']
+ now as normal user open phpMyAdmin and for each one of your
tables where you want to use this feature, click
"Structure/Relation view/" and choose foreign fields.
Please note that in the current (2.3.0) version, master_db must
be the same as foreign_db. Those fields have been put in future
development of the cross-db relations.
$cfg['Servers'][$i]['table_info'] string
Since release 2.3.0 you can describe, in a special 'table_info'
table, which field is to be displayed as a tooltip when moving
the cursor over the corresponding key.
This configuration variable will hold the name of this special
table. To allow the usage of this functionality the superuser
has to:
+ set up "pmadb" as described above
+ within this database create a table following this scheme:
CREATE TABLE `PMA_table_info` (
`db_name` varchar(64) NOT NULL default '',
`table_name` varchar(64) NOT NULL default '',
`display_field` varchar(64) NOT NULL default '',
PRIMARY KEY (`db_name`, `table_name`)
) TYPE=MyISAM COMMENT='Table information for
phpMyAdmin';
+ put the table name in $cfg['Servers'][$i]['table_info']
+ then for each table where you want to use this feature, click
"Structure/Relation view/Choose field to display" to choose
the field.
Usage tip: Display field.
$cfg['Servers'][$i]['table_coords'] string
$cfg['Servers'][$i]['pdf_pages'] string
Since release 2.3.0 you can have phpMyAdmin create PDF pages
showing the relations between your tables. To do this it needs
two tables "pdf_pages" (storing information about the available
pdf pages) and "table_coords" (storing coordinates where each
table will be placed on a PDF schema output).
You must be using the "relation" feature and have a table of
PDF pages (see $cfg['Servers'][$i]['pdf_pages']) to create PDF
output.
To allow the usage of this functionality the superuser has to:
+ set up "pmadb" as described above
+ within this database create a table following this scheme:
CREATE TABLE `PMA_table_coords` (
`db_name` varchar(64) NOT NULL default '',
`table_name` varchar(64) NOT NULL default '',
`pdf_page_number` int NOT NULL default '0',
`x` float unsigned NOT NULL default '0',
`y` float unsigned NOT NULL default '0',
PRIMARY KEY (`db_name`, `table_name`,
`pdf_page_number`)
) TYPE=MyISAM COMMENT='Table coordinates for phpMyAdmin
PDF output';
+ also within this database create:
CREATE TABLE `PMA_pdf_pages` (
`db_name` varchar(64) NOT NULL default '',
`page_nr` int(10) unsigned NOT NULL auto_increment,
`page_descr` varchar(50) NOT NULL default '',
PRIMARY KEY (page_nr),
KEY (db_name)
) TYPE=MyISAM COMMENT='PDF Relationpages for PMA';
+ put the first table name in
$cfg['Servers'][$i]['table_coords'] and the second table name
in $cfg['Servers'][$i]['pdf_pages']
Usage tips: PDF output.
$cfg['Servers'][$i]['column_comments'] string
Since release 2.3.0 you can store comments to describe each
column for each table. These will then be shown on the
"printview".
To allow the usage of this functionality the superuser has to:
+ set up "pmadb" as described above
+ within this database create a table following this scheme:
CREATE TABLE `PMA_column_comments` (
id int(5) unsigned NOT NULL auto_increment,
db_name varchar(64) NOT NULL default '',
table_name varchar(64) NOT NULL default '',
column_name varchar(64) NOT NULL default '',
comment varchar(255) NOT NULL default '',
PRIMARY KEY (id),
UNIQUE KEY db_name (db_name, table_name, column_name)
) TYPE=MyISAM COMMENT='Comments for Columns';
+ put the table name in $cfg['Servers'][$i]['column_comments']
$cfg['Servers'][$i]['AllowDeny']['order'] string
If your rule order is empty, then IP authentication is
disabled.
If your rule order is set to 'deny,allow' then the system
applies all deny rules followed by allow rules. Access is
allowed by default. Any client which does not match a Deny
command or does match an Allow command will be allowed access
to the server.
If your rule order is set to 'allow,deny' then the system
applies all allow rules followed by deny rules. Access is
denied by default. Any client which does not match an Allow
directive or does match a Deny directive will be denied access
to the server.
If your rule order is set to 'explicit', the authentication is
performed in a similar fashion to rule order 'deny,allow', with
the added restriction that your host/username combination must
be listed in the allow rules, and not listed in the deny rules.
This is the most secure means of using Allow/Deny rules, and
was available in Apache by specifying allow and deny rules
without setting any order.
$cfg['Servers'][$i]['AllowDeny']['rules'] array of strings
The general format for the rules is as such:
<'allow' | 'deny'> <username> [from] <ipmask>
If you wish to match all users, it is possible to use a '%' as
a wildcard in the username field.
There are a few shortcuts you can use in the ipmask field as
well:
'all' -> 0.0.0.0/0
'localhost' -> 127.0.0.1/8
Having an empty rule list is equivalent to either using 'allow
% from all' if your rule order is set to 'deny,allow' or 'deny
% from all' if your rule order is set to 'allow,deny' or
'explicit'.
For the IP matching system, the following work:
xxx.xxx.xxx.xxx (an exact IP address)
xxx.xxx.xxx.[yyy-zzz] (an IP address range)
xxx.xxx.xxx.xxx/nn (CIDR, Classless Inter-Domain Routing type
IP addresses)
But the following does not work:
xxx.xxx.xxx.xx[yyy-zzz] (partial IP address range)
$cfg['ServerDefault'] integer
If you have more than one server configured, you can set
$cfg['ServerDefault'] to any one of them to autoconnect to that
server when phpMyAdmin is started, or set it to 0 to be given a
list of servers without logging in.
If you have only one server configured, $cfg['ServerDefault']
MUST be set to that server.
$cfg['OBGzip'] boolean
Defines whether to use gzip output buffering for increased
speed in HTTP transfers.
$cfg['PersistentConnections'] boolean
Whether persistent connections should be used or not
(mysql_connect or mysql_pconnect).
$cfg['ExecTimeLimit'] integer [number of seconds]
Set the number of seconds a script is allowed to run. If
seconds is set to zero, no time limit is imposed.
This setting is used while importing/exporting dump files but
has no effect when PHP is running in safe mode.
$cfg['SkipLockedTables'] boolean
Mark used tables and make it possible to show databases with
locked tables (since 3.23.30).
$cfg['ShowSQL'] boolean
Defines whether sql-queries generated by phpMyAdmin should be
displayed or not.
$cfg['AllowUserDropDatabase'] boolean
Defines whether normal users (non-administrator) are allowed to
delete their own database or not. If set as FALSE, the link
"Drop Database" will not be shown, and even a "DROP DATABASE
mydatabase" will be rejected. Quite practical for ISP's with
many customers.
$cfg['Confirm'] boolean
Whether a warning ("Are your really sure..") should be
displayed when you're about to loose data.
$cfg['LoginCookieRecall'] boolean
Define whether the previous login should be recalled or not in
cookie authentication mode.
$cfg['UseDbSearch'] boolean
Define whether the "search string inside database" is enabled
or not.
$cfg['LeftFrameLight'] boolean
Defines whether to use select-based menu and display only the
current tables in the left frame (smaller page).
$cfg['ShowTooltip'] boolean
Defines whether to display table comment as tooltip in left
frame or not.
$cfg['ShowStats'] boolean
Defines whether to display space usage and statistics about
databases and tables or not.
Note that statistics requires at least MySQL 3.23.3 and that,
at this date, MySQL doesn't return such information for
Berkeley DB tables.
$cfg['ShowMysqlInfo'] boolean
$cfg['ShowMysqlVars'] boolean
$cfg['ShowPhpInfo'] boolean
$cfg['ShowChgPassword'] boolean
Defines whether to display the "MySQL runtime information",
"MySQL system variables", "PHP information" and "Change
password " links or not for simple users at the starting main
(right) frame. This setting does not check MySQL commands
entered directly.
Please note that to block the usage of phpinfo() in scripts,
you have to put this in your php.ini:
disable_functions = phpinfo()
Also note that enabling the "Change password " link has no
effect with "config" authentication mode: because of the hard
coded password value in the configuration file, end users can't
be allowed to change their passwords.
$cfg['SuggestDBName'] boolean
Defines whether to suggest a database name on the "Create
Database" form or to keep the textfield empty.
$cfg['ShowBlob'] boolean
Defines whether BLOB fields are shown when browsing a table's
content or not.
$cfg['NavigationBarIconic'] boolean
Defines whether navigation bar buttons contain text or symbols
only.
$cfg['ShowAll'] boolean
Defines whether an user should be displayed a "show all
(records)" button in browse mode or not.
$cfg['MaxRows'] integer
Number of rows displayed when browsing a resultset. If the
resultset contains more rows, Previous/Next links will be
shown.
$cfg['Order'] string [DESC|ASC|SMART]
Defines whether fields are displayed in ascending (ASC) order,
in descending (DESC) order or in a "smart" (SMART) order -ie
descending order for fields of type TIME, DATE, DATETIME &
TIMESTAMP, ascending order else- by default.
$cfg['ProtectBinary'] boolean or string
Defines whether BLOB or BINARY fields are protected from
edition when browsing a table's content or not. Valid values
are:
- FALSE to allow edition of all fields;
- blob to allow edition of all fields except BLOBS;
- all to disallow edition of all BINARY or BLOB fields.
$cfg['ShowFunctionFields'] boolean
Defines whether MySQL functions fields should be displayed or
not in edit/insert mode.
$cfg['CharEditing'] string
Defines which type of editing controls should be used for CHAR
and VARCHAR fields. Possible values are:
+ input - this allows to limit size of text to size of field in
MySQL, but has problems with newlines in fields
+ textarea - no problems with newlines in fields, but also no
length limitations
Default is old behavior so input.
$cfg['ZipDump'] boolean
$cfg['GZipDump'] boolean
$cfg['BZipDump'] boolean
Defines whether to allow the use of zip/gzip/bzip compression
when creating a dump file or not.
$cfg['DefaultTabDatabase'] string
Defines the tab displayed by default on database view. Possible
values: "db_details_structure.php3", "db_details.php3" or
"db_search.php3".
$cfg['DefaultTabTable'] string
Defines the tab displayed by default on table view. Possible
values: "tbl_properties_structure.php3", "tbl_properties.php3",
"tbl_select.php3" or "tbl_change.php3".
$cfg['MySQLManualBase'] string
If set to an URL which points to the MySQL documentation (type
depends on $cfg['MySQLManualType']), appropriate help links are
generated.
See MySQL Documentation page for more information about MySQL
manuals and their types.
$cfg['MySQLManualType'] string
Type of MySQL documentation:
+ old - old style used in phpMyAdmin 2.3.0 and sooner
+ searchable - "Searchable, with user comments"
+ chapters - "HTML, one page per chapter"
+ big - "HTML, all on one page"
+ none - do not show documentation links
$cfg['DefaultLang'] string
Defines the default language to use, if not browser-defined or
user-defined.
See the select_lang.inc.php3 script to know the valid values
for this setting.
$cfg['Lang'] string
Force: always use this language (must be defined in the
select_lang.inc.php3 script).
$cfg['DefaultCharset'] string
Default charset to use for recoding of MySQL queries. This must
be enabled and it's described by $cfg['AllowAnywhereRecoding']
option.
You can give here any charset which is in
$cfg['AvailableCharsets'] array and this is just default
choice, user can select any of them.
$cfg['AllowAnywhereRecoding'] boolean
Allow charset recoding of MySQL queries. You need recode or
iconv support (compiled in or module) in php to allow MySQL
queries recoding and used language file must have it enabled
(by default only these which are in unicode, just to avoid
losing some characters).
$cfg['RecodingEngine'] string
You can select here which functions will be used for charset
conversion. Possible values are:
+ auto - automatically use available one (first is tested
iconv, then recode)
+ iconv - use iconv or libiconv functions
+ recode - use recode_string function
Default is auto.
$cfg['AvailableCharsets'] array
Available charsets for MySQL conversion. You can add your own
(any of supported by recode/iconv) or remove these which you
don't use. Charsets will be shown in same order as here listed,
so if you frequently use some of these move them to the top.
$cfg['LeftWidth'] integer
Left frame width in pixel.
$cfg['LeftBgColor'] string [HTML color]
$cfg['RightBgColor'] string [HTML color]
The background colors (HTML) used for both the frames.
$cfg['RightBgImage'] string
The URI of the background image used for the right frame. It
can be absolute as well as relative from your phpMyAdmin
directory.
$cfg['LeftPointerColor'] string [HTML color]
The color (HTML) used for the pointer in the left frame (does
not work with NS4).
$cfg['Border'] integer
The size of a table's border.
$cfg['ThBgcolor'] string [HTML color]
The color (HTML) used for table headers.
$cfg['BgcolorOne'] string [HTML color]
The color (HTML) #1 for table rows.
$cfg['BgcolorTwo'] string [HTML color]
The color (HTML) #2 for table rows.
$cfg['BrowsePointerColor'] string [HTML color]
$cfg['BrowseMarkerColor'] string [HTML color]
The colors (HTML) uses for the pointer and the marker in browse
mode (does not work with NS4).
The former feature highlights the row over which your mouse is
passing and the latter lets you visually mark/unmark rows by
clicking on them.
You can disable both of these features by emptying the
respective directive.
$cfg['TextareaCols'] integer
$cfg['TextareaRows'] integer
$cfg['CharTextareaCols'] integer
$cfg['CharTextareaRows'] integer
Number of columns and rows for the textareas.
This value will be emphasized (*2) for sql query textareas.
The Char* values are used for CHAR and VARCHAR editing (if
configured via $cfg['CharEditing']).
$cfg['TextareaAutoSelect'] boolean
Defines if the whole textarea of the query box will be selected
on click.
$cfg['LimitChars'] integer
Maximal number of Chars showed in a TEXT OR a BLOB field on
browse view. Can be turned off by a toggle button on the browse
page.
$cfg['ModifyDeleteAtLeft'] boolean
$cfg['ModifyDeleteAtRight'] boolean
Defines the place where modify and delete links would be put
when tables contents are displayed (you may have them displayed
both at the left and at the right). "Left" and "right" are
parsed as "top" and "bottom" with vertical display mode.
$cfg['DefaultDisplay'] string
There are 2 display modes: horizontal and vertical. Define
which one is displayed by default.
$cfg['UploadDir'] string
The name of the directory, ending with a slash, where SQL files
have been uploaded by other means than phpMyAdmin (for example,
ftp). Those files are available under a drop-down box when you
click the database name, then the SQL tab.
Please note that the file names must have the suffix ".sql".
This feature is useful when your file is too big to be uploaded
via HTTP, or when file uploads are disabled in PHP.
Please note that if PHP is running in safe mode, this directory
must be owned by the same user as the owner of the phpMyAdmin
scripts.
$cfg['RepeatCells'] integer
Repeat the headers every X cells, or 0 to deactivate.
$cfg['SQP']['enable'] boolean
As of phpMyAdmin 2.3.0, we now have a fully functional SQL
Parser system. It is enabled by default, as it is used to
format the SQL queries.
As of 2.3.1, it will become an integral part of phpMyAdmin, as
it will analyze certain queries to improve the behavior of
phpMyAdmin. But as it is very new, and not yet heavily used, we
offer you an option to turn it off.
$cfg['SQP']['fmtType'] string [html|none]
The main use of the new SQL Parser is to pretty-print SQL
queries. By default we use HTML to format the query, but you
can disable this by setting this varible to 'none'
$cfg['SQP']['fmtInd'] float
$cfg['SQP']['fmtIndUnit'] string [em|px|pt|ex]
For the pretty-printing of SQL queries, under some cases the
part of a query inside a bracket is indented. By changing
$cfg['SQP']['fmtInd'] you can change the amount of this indent.
Related in purpose is $cfg['SQP']['fmtIndUnit'] which specifies
the units of the indent amount that you specified. This is used
via stylesheets.
$cfg['SQP']['fmtColor'] array of string tuples
This array is used to define the colours for each type of
element of the pretty-printed SQL queries. The tuple format is
class => [HTML colour code | empty string]
If you specify an empty string for the color of a class, it is
ignored in creating the stylesheet. You should not alter the
class names, only the colour strings.
Class name key:
+ comment Applies to all comment sub-classes
+ comment_mysql Comments as "#...\n"
+ comment_ansi Comments as "-- ...\n"
+ comment_c Comments as "/*...*/"
+ digit Applies to all digit sub-classes
+ digit_hex Hexadecimal numbers
+ digit_integer Integer numbers
+ digit_float Floating point numbers
+ punct Applies to all punctuation sub-classes
+ punct_bracket_open_round Opening brackets"("
+ punct_bracket_close_round Closing brackets ")"
+ punct_listsep List item seperator ","
+ punct_qualifier Table/Column Qualifer "."
+ punct_queryend End of query marker ";"
+ alpha Applies to all alphabetic classes
+ alpha_columnType Identifers matching a column type
+ alpha_columnAttrib Identifers matching a
database/table/column attribute
+ alpha_functionName Identifiers matching a MySQL function name
+ alpha_reservedWord Identifiers matching any other reserved
word
+ alpha_variable Identifers matching a SQL variable "@foo"
+ alpha_identifier All other identifiers
+ quote Applies to all quotation mark classes
+ quote_double Double quotes "
+ quote_single Single quotes '
+ quote_backtick Backtick quotes `
$cfg['SQLValidator']['use'] boolean
phpMyAdmin now supports use of the Mimer SQL Validator service,
as originally published on Slashdot.
For help in setting up your system to use the service, see the
FAQ #6.14.
$cfg['SQLValidator']['username'] string
$cfg['SQLValidator']['password'] string
The SOAP service allows you to login with anonymous and any
password, so we use those by default.. Instead, if you have an
account with them, you can put your login details here, and it
will be used in place of the anonymous login.
$cfg['DBG']['enable'] boolean
DEVELOPERS ONLY!
Enable the DBG extension for debugging phpMyAdmin. Required for
profiling the code.
For help in setting up your system to this, see the Developers
section.
$cfg['DBG']['profile']['enable'] boolean
DEVELOPERS ONLY!
Enable profiling support for phpMyAdmin. This will append a
chunk of data to the end of every page displayed in the main
window with profiling statistics for that page.
You may need need to increase the maximum execution time for
this to complete successfully.
$cfg['DBG']['profile']['threshold'] float (units in milliseconds)
DEVELOPERS ONLY!
When profiling data is displayed, this variable controls the
threshold of display for any profiling data, based on the
average time each time has taken. If it is over the threshold
it is displayed, otherwise it is not displayed. This takes a
value in milliseconds. In most cases you don't need to edit
this.
$cfg['ColumnTypes'] array
All possible types of a MySQL column. In most cases you don't
need to edit this.
$cfg['AttributeTypes'] array
Possible attributes for fields. In most cases you don't need to
edit this.
$cfg['Functions'] array
A list of functions MySQL supports. In most cases you don't
need to edit this.
FAQ - Frequently Asked Questions
Server - Configuration - Limitations - Multi-user - Browsers
- Usage tips - Project
[1. Server]
[1.1] I'm running php 4+ and my server is crashing each time a specific
action is required or phpMyAdmin sends a blank page or a page full of
cryptic characters to my browser, what can I do
There are some known php bugs with output buffering and compression.
Try to set the $cfg['OBGzip'] directive to FALSE in your
config.inc.php or .php3 file and the zlib.output_compression directive
to Off in your php configuration file.
Furthermore, we know about such problems connected to the release
candidates of php 4.2.0 (tested with php 4.2.0 RC1 to RC4) together
with MS Internet Explorer. Please upgrade to the release version php
4.2.0.
[1.2] My Apache server crashes when using phpMyAdmin
You should first try the latest versions of Apache (and possibly
MySQL).
See also the other FAQ entry about php bugs with output buffering.
If your server keeps crashing, please ask for help in the various
Apache support groups.
[1.3] I'm running phpMyAdmin with "cookie" authentication mode under PHP
4.2.0 or 4.2.1 loaded as an Apache 2+ module but can't enter the script:
I'm always displayed the login screen
This is a known PHP bug (see this bug report) from the official php
bug database. It means there is and won't be any phpMyAdmin fix
against it because there is no way to code a fix.
[1.4] Using phpMyAdmin on IIS, I'm displayed the error message: "The
specified CGI application misbehaved by not returning a complete set of
HTTP headers...."
You just forgot to read the install.txt file from the php
distribution. Have a look at the last message in this bug report from
the official php bug database.
[1.5] Using phpMyAdmin on IIS, I'm facing crashes and/or many error
messages with the http or advanced authentication mode
This is a known problem with the php ISAPI filter: it's not so stable.
For some more information and complete testings see the messages
posted by Andr<64> B. aka "djdeluxe76" in this thread from the phpWizard
forum.
Please use instead the cookie authentication mode.
[1.6] I can't use phpMyAdmin on PWS: nothing is displayed!
This seems to be a PWS bug. Filippo Simoncini found a workaroud (at
this time there is no better fix): remove or comment the DOCTYPE
declarations (2 lines) from the scripts header.inc.php3,
header_printview.inc.php3, index.php3, left.php3 and
libraries/common.lib.php3.
[1.7] How can I GZip or Bzip a dump or a CSV export. It seems to not work
These features are based on the gzencode() and bzcompress() php
functions to be more independent of the platform (Unix/Windows, Safe
Mode or not, and so on). So, you must have PHP4 >= 4.0.4 and
Zlib/Bzip2 support (--with-zlib and --with-bz2).
We faced php crashes when trying to download a dump with MS Internet
Explorer when phpMyAdmin is run with a release candidate of php 4.2.0.
In this case you should switch to the release version of php 4.2.0.
[1.8] I cannot insert a text file in a table, and I get an error about safe
mode being in effect
Your uploaded file is saved by PHP in the "upload dir", as defined in
php.ini by the variable upload_tmp_dir (usually the system default is
/tmp).
We recommend the following setup for Apache servers running in safe
mode, to enable uploads of files while being reasonably secure:
* create a separate directory for uploads: mkdir /tmp/php
* give ownership to the Apache server's user.group: chown
apache.apache /tmp/php
* give proper permission: chmod 600 /tmp/php
* put upload_tmp_dir = /tmp/php in php.ini
* restart Apache
[1.9] I'm having troubles when uploading files. In general file uploads
don't work on my system and uploaded files have a Content-Type: header in
the first line
It's not really phpMyAdmin related but RedHat 7.0. You have a RedHat
7.0 and you updated your php rpm to php-4.0.4pl1-3.i386.rpm, didn't
you?
So the problem is that this package has a serious bug that was
corrected ages ago in php (2001-01-28: see php's bug tracking system
for more details). The problem is that the bugged package is still
available though it was corrected (see redhat's bugzilla for more
details).
So please download the fixed package (4.0.4pl1-9) and the problem
should go away.
And that fixes the \r\n problem with file uploads!
[1.10] I'm having troubles when uploading files with phpMyAdmin running on
a secure server. My browser is Internet Explorer and I'm using the Apache
server
As suggested by "Rob M" in the phpWizard forum, add this line to your
httpd.conf:
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
It seems to clear up many problems between IE and SSL.
[1.11] I get an 'open_basedir restriction' while uploading a file from the
query box
Since version 2.2.4, phpMyAdmin supports servers with open_basedir
restrictions. Assuming that the restriction allows you to open files
in the current directory ('.'), all you have to do is create a 'tmp'
directory under the phpMyAdmin install directory, with permissions 777
and the same owner as the owner of your phpMyAdmin directory. The
uploaded files will be moved there, and after execution of your SQL
commands, removed.
[1.12] I have lost my MySQL root password, what can I do
The MySql manual explains how to reset the permissions.
[1.13] I get an error 'No SQL query' when trying to execute a bookmark
If PHP does not have read/write access to its upload_tmp_dir, it
cannot access the uploaded query.
[1.14] I get an error 'No SQL query' when trying to submit a query from the
convenient text area
Check the post_max_size directive from your php configuration file and
try to increase it.
[1.15] I have problems with mysql.user field names
In older MySQL versions, the User and Password fields were named user
and password. Please modify your field names to align with current
standards.
[1.16] I cannot upload big dump files
The first things to check (or ask your host provider to check) are the
values of upload_max_filesize, memory_limit and post_max_size in the
php.ini configuration file.
All of these three settings limit the maximum size of data that can be
submitted and handled by php. One user also said that post_max_size
and memory_limit need to be larger than upload_max_filesize.
[1.17] Does phpMyAdmin support MySQL 4
MySQL 4 is not yet fully supported by phpMyAdmin.
Because of MySQL 4's backwards compatibility you can use phpMyAdmin
for administering MySQL 4 servers, but phpMyAdmin does not yet support
its new features. Please notice that in this case it is recommended to
use php >= 4.1 since older versions of php are not compatible to
MySQL 4.
Furthermore, several users reported problems with phpMyAdmin related
to bugs in MySQL 4. MySQL 4 is still a beta release and should be used
for test purposes only! Because of a major change in the definition
syntax of string field types, this version of phpMyAdmin probably
won't work correctly with MySQL >= 4.1.0! We will work on the support
as soon as MySQL 4.1.0 is released.
[1.18] I'm running MySQL <= 4.0.1 having lower_case_table_names set to 1.
If I create a new table with a capital letter in its name it is changed to
lowercase as it should. But if I try to DROP this table MySQL is unable to
find the corresponding file
This is a bug of MySQL <= 4.0.1. Please upgrade to at least
MySQL 4.0.2 or turn off your lower_case_table_names directive.
[1.19] I can't run the "display relations" feature because the script seems
not to know the font face I'm using!
The "FPDF" library we're using for this feature requires some special
files to use font faces.
Please refers to the FPDF manual to build these files.
[1.20] I receive the error "cannot load MySQL extension, please check PHP
Configuration"
To connect to a MySQL server, PHP needs a set of MySQL functions
called "MySQL extension". This extension may be part of the PHP server
(compiled-in), otherwise it needs to be loaded dynamically. Its name
is probably mysql.so or mysql.dll. phpMyAdmin tried to load the
extension but failed.
Usually, the problem is solved by installing a software package called
"PHP-MySQL" or something similar.
[1.21] I am running the CGI version of PHP under Unix, and I cannot login
using cookie auth
In php.ini, set mysql.max_links higher than 1.
[1.22] I don't see the "Location of text file" field, so I cannot upload
This is most likely because in php.ini, your file_uploads parameter is
not set to "on".
[1.23] I'm running MySQL on a Win32 machine. Each time I create a new table
the table and field names are changed to lowercase!
This happens because the MySQL directive lower_case_table_names
defaults to 1 (ON) in the Win32 version of MySQL. You can change this
behavior by simply changing the directive to 0 (OFF):
Just edit you my.ini file that should be located in your Windows
directory and add the following line:
lower-case-table-names=0
Next, save the file and restart the MySQL service. You can always
check the value of this directive using the query
SHOW VARIABLES LIKE 'lower_case_table_names';
[1.24] Some characters are being truncated in my queries, or I get
characters randomly added. I am running PHP 4.2.3
This is a PHP 4.2.3 bug.
[1.25] I am running Apache with mod_gzip-1.3.26.1a on Windows XP, and I get
problems, such as undefined variables when I run a SQL query
A tip from Jose Fandos: put a comment on the following two lines in
httpd.conf, like this:
# mod_gzip_item_include file \.php$
# mod_gzip_item_include mime "application/x-httpd-php.*"
as this version of mod_gzip on Apache (Windows) has problems handling
php scripts. Of course you have to restart Apache.
[1.26] I just installed phpMyAdmin in my document root of IIS but I get the
error "No input file specified" when trying to run phpMyAdmin.
This is a permission problem. Right-click on the phpmyadmin folder and
choose properties. Under the tab Security, click on "Add" and select
the user "IUSER_machine" from the list. Now set his permissions and it
should work.
[1.27] I get empty page when I want to view huge page (eg.
db_details_structure.php3 with plenty of dabases)
This is a PHP bug that occur when GZIP output buffering enabled. If
you turn off it (by $cfg['OBGzip'] = FALSE in config.inc.php3), it
should work. This bug will be fixed in PHP 5.0.0.
[2. Configuration]
[2.1] The error message "Warning: Cannot add header information - headers
already sent by ..." is displayed, what's the problem
Edit your config.inc.php or .php3 file and ensure there is nothing (ie
no blank lines, no spaces, no characters...) neither before the <?php
tag at the beginning, neither after the ?> tag at the end.
[2.2] phpMyAdmin can't connect to MySQL. What's wrong
Either there is an error with your PHP setup or your username/password
is wrong. Try to make a small script which uses mysql_connect and see
if it works. If it doesn't, it may be you haven't even compiled MySQL
support into PHP.
[2.3] The error message "Warning: MySQL Connection Failed: Can't connect to
local MySQL server through socket '/tmp/mysql.sock' (111)..." is displayed.
What can I do
For RedHat users, Harald Legner suggests this on the mailing list:
On my RedHat-Box the socket of mysql is /var/lib/mysql/mysql.sock. In
your php.ini you will find a line
mysql.default_socket = /tmp/mysql.sock
change it to
mysql.default_socket = /var/lib/mysql/mysql.sock
Then restart apache and it will work.
Here is a fix suggested by Brad Ummer in the phpwizard forum:
* First, you need to determine what socket is being used by MySQL.
To do this, telnet to your server and go to the MySQL bin
directory. In this directory there should be a file named
mysqladmin. Type ./mysqladmin variables, and this should give you
a bunch of info about your MySQL server, including the socket
(/tmp/mysql.sock, for example).
* Then, you need to tell PHP to use this socket.
Assuming you are using PHP 3.0.10 or better, you can specify the
socket to use when you open the connection. To do this in
phpMyAdmin, you need to complete the socket information in the
config.inc.php3.
For example: $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';
Have also a look at the corresponding section of the MySQL
documentation.
[2.4] Nothing is displayed by my browser when I try to run phpMyAdmin, what
can I do
Try to set the $cfg['OBGZip'] directive to FALSE in the phpMyAdmin
configuration file. It helps sometime.
Also have a look at your php version number: if it contains "4.0b..."
it means you're running a beta version of PHP. That's not a so good
idea, please upgrade to a plain revision.
[2.5] Each time I want to insert or change a record or drop a database or a
table, an error 404 (page not found) is displayed or, with http or cookie
authentication, I'm asked to login again. What's wrong
Check the value you set for the $cfg['PmaAbsoluteUri'] directive in
the phpMyAdmin configuration file.
[3. Known limitations]
[3.1] When using http authentication, an user who logged out can not relog
in with the same nick
This is related to the authentication mechanism (protocol) used by
phpMyAdmin. We plan to change it as soon as we may find enough free
time to do it, but you can bypass this problem: just close all the
opened browser windows and then go back to phpMyAdmin. You should be
able to logs in again.
[3.2] When dumping a large table in compressed mode, I get a memory limit
error or a time limit error
As of version 2.2.4, we build the compressed dump in memory, so large
tables dumps may hang. The only alternative we can think about (using
system calls to mysqldump then gzip or bzip2) would not be applicable
in environments where PHP is in safe mode: access to system programs
is is limited by the system administrator, and time limit is enforced.
[3.3] With InnoDB tables, I lose foreign key relationships when I rename or
alter a table
This seems to be a InnoDB bug (fixed in MySQL 3.23.50?). However, keep
in mind that phpMyAdmin as of version 2.3.0 does not support InnoDB.
[3.4] I am unable to import dumps I created with the mysqldump tool bundled
with the MySQL server distribution
The problem is that mysqldump creates invalid comments like this:
-- MySQL dump 8.22
--
-- Host: localhost Database: database
---------------------------------------------------------
-- Server version 3.23.54
The invalid part of the code is the horizontal line made of dashes
that appears once in every dump created with mysqldump. If you want to
run your dump you have to turn it into valid MySQL. This means, you
have to add a whitespace after the first to dashes of the line or add
a # before it:
-- -------------------------------------------------------
or
#---------------------------------------------------------
[4. ISPs, multi-user installations ]
[4.1] I'm an ISP. Can I setup one central copy of phpMyAdmin or do I need
to install it for each customer
Since version 2.0.3, you can setup a central copy of phpMyAdmin for
all your users. The development of this feature was kindly sponsored
by NetCologne GmbH. This requires a properly setup MySQL user
management and phpMyAdmin http or cookie authentication. See the
install section on "Using http authentication".
[4.2] What's the preferred way of making phpMyAdmin secure against evil
access
This depends on your system.
If you're running a server which cannot be accessed by other people,
it's sufficient to use the directory protection bundled with your
webserver (with Apache you can use .htaccess files, for example).
If other people have telnet access to your server, you should use
phpMyAdmin's http authentication feature.
Suggestions:
* Your config.inc.php3 file should be chmod 660.
* All your phpMyAdmin files should be chown phpmy.apache, where
phpmy is a user whose password is only known to you, and apache is
the group under which Apache runs.
* You should use PHP safe mode, to protect from other users that try
to include your config.inc.php3 in their scripts.
[4.3] I get errors about not being able to include a file in /lang or in
/libraries
Check php.ini, or ask your sysadmin to check it. The include_path must
contain "." somewhere in it, and open_basedir, if used, must contain
"." and "./lang" to allow normal operation of phpMyAdmin.
[4.4] phpMyAdmin always gives "Access denied" when using http
authentication
This could happen for several reasons:
* $cfg['Servers'][$i]['controluser'] and/or
$cfg['Servers'][$i]['controlpass'] are wrong.
* The username/password you specify in the login-dialog are invalid.
* You have already setup a security mechanism for the
phpMyAdmin-directory, eg. a .htaccess file. This would interfere
with phpMyAdmin's authentication, so remove it.
[4.5] Is it possible to let users create their own databases
Starting with 2.2.5, in the user management page, you can enter a
wildcard database name for a user, and put the privileges you want.
For example, adding SELECT, INSERT, UPDATE, DELETE, CREATE, DROP,
INDEX, ALTER would let a user create/manage his/her database(s).
[4.6] How can I use the Host-based authentication additions
If you have existing rules from an old .htaccess file, you can take
them and add a username between the 'deny'/'allow' and 'from' strings.
Using the username wildcard of '%' would be a major benefit here if
your installation is suited to using it. Then you can just add those
updated lines into the $cfg['Servers'][$i]['AllowDeny']['rules']
array.
If you want a pre-made sample, you can try this fragment. It stops the
'root' user from logging in from any networks other than the private
network IP blocks.
//block root from logging in except from the private networks
$cfg['Servers'][$i]['AllowDeny']['order'] = 'deny,allow';
$cfg['Servers'][$i]['AllowDeny']['rules'] = array(
'deny root from all',
'allow root from localhost',
'allow root from 10.0.0.0/8',
'allow root from 192.168.0.0/16',
'allow root from 172.16.0.0/12',
);
[5. Browsers or client OS]
[5.1] I get an out of memory error, and my controls are non-functional,
when trying to create a table with more than 14 fields
We could reproduce this problem only under Win98/98SE. Testing under
WinNT4 or Win2K, we could easily create more than 60 fields.
A workaround is to create a smaller number of fields, then come back
to your table properties and add the other fields.
[5.2] With Xitami 2.5b4, phpMyAdmin won't process form fields
This is not a phpMyAdmin problem but a Xitami known bug: you'll face
it with each script/website that use forms.
Upgrade or downgrade your Xitami server.
[5.3] I have problems dumping tables with Konqueror (phpMyAdmin 2.2.2)
With Konqueror 2.1.1: plain dumps, zip and gzip dumps work ok, except
that the proposed file name for the dump is always 'tbl_dump.php'.
Bzip2 dumps don't seem to work.
With Konqueror 2.2.1: plain dumps work; zip dumps are placed into the
user's temporary directory, so they must be moved before closing
Konqueror, or else they disappear. Gzip dumps give an error message.
Testing needs to be done for Konqueror 2.2.2.
[5.4] I can't use the cookie authentication mode because Internet Explorer
never stores the cookies
MS Internet Explorer seems to be really buggy about cookies, at least
till version 6. And thanks to Andrew Zivolup we've traced also a php
4.1.1 bug in this area!
Then, if you're running php 4.1.1, try to upgrade or downgrade... it
may work!
[5.5] In Internet Explorer 5.0, I get Javascript errors when browsing my
rows
Upgrade to at least Internet Explorer 5.5SP2.
[5.6] In Internet Explorer 5.0, 5.5 or 6.0, I get an error when trying to
modify a row in a table with many fields, or with a text field
Your table neither have a primary key nor an unique one, so we must
use a long URL to identify this row. There is a limit on the lenght of
the URL in those browsers, and this not happen in Netscape, for
example. The workaround is to create a primary or unique key, or use
another browser.
[5.7] I refresh (reload) my browser, and come back to the welcome page
Some browsers support right-clicking into the frame you want to
refresh, just do this in the right frame.
[5.8] With Mozilla 0.9.7 I have problems sending a query modified in the
query box
Looks like a Mozilla bug: 0.9.6 was ok. We will keep an eye on future
Mozilla versions.
[5.9] With Mozilla 0.9.? to 1.0 and Netscape 7.0-PR1 I can't type a
whitespace in the SQL-Query edit area: the page scrolls down
This is a Mozilla bug (see bug #26882 at Bugzilla).
[5.10] With Netscape 4.75 I get empty rows between each row of data in a
CSV exported file
This is a known Netscape 4.75 bug: it adds some line feeds when
exporting data in octet-stream mode. Since we can't detect the
specific Netscape version, we cannot workaround this bug.
[5.11] Extended-ASCII characters like German umlauts are displayed wrong
Please ensure that you have set your browser's charset to the one of
the language file you have selected on phpMyAdmin's start page.
Alternatively, you can try the auto detection mode that is supported
by the recent versions of the most browsers.
[5.12] Apple OS X: Safari browser changes special characters to "?"
This issue has been reported by a OS X user, who adds that Chimera,
Netscape and Mozilla do not have this problem.
[5.13] With Internet Explorer 5.5 or 6, and http authentication type, I
cannot manage two servers: I login to the first one, then the other one,
but if I switch back to the first, I have to login on each operation.
This is a bug in Internet Explorer, other browsers do not behave this
way.
[6. Using phpMyAdmin]
[6.1] I can't insert new rows into a table / I can't create a table - MySQL
brings up a SQL-error
Examine the SQL error with care. Often the problem is caused by
specifying a wrong field-type.
Common errors include:
* Using VARCHAR without a size argument
* Using TEXT or BLOB with a size argument
Also, look at the syntax chapter in the MySQL manual to confirm that
your syntax is correct.
[6.2] When I create a table, I click the Index checkbox for 2 fields and
phpMyAdmin generates only one index with those 2 fields
In phpMyAdmin 2.2.0 and 2.2.1, this is the way to create a
multi-fields index. If you want two indexes, create the first one when
creating the table, save, then display the table properties and click
the Index link to create the other index.
[6.3] How can I insert a null value into my table
Since version 2.2.3, you have a checkbox for each field that can be
null. Before 2.2.3, you had to enter "null", without the quotes, as
the field's value.
[6.4] How can I backup my database or table
Click on a database or table name in the left frame, the properties
will be displayed. Then on the menu, click "Export", you can dump the
structure, the data, or both. This will generate standard SQL
statements that can be used to recreate your database/table.
You will need to choose "Save as file", so that phpMyAdmin can
transmit the resulting dump to your station. Depending on your PHP
configuration, you will see options to compress the dump. See also the
$cfg['ExecTimeLimit'] configuration variable.
For additional help on this subject, look for the word "dump" in this
document.
[6.5] How can I restore (upload) my database or table using a dump? How can
I run a ".sql" file
Click on a database name in the left frame, the properties will be
local displayed. Then in the "Run SQL query" section, type in your
dump filename, or use the Browse button. Then click Go.
For additional help on this subject, look for the word "upload" in
this document.
[6.6] How can I use the relation table in Query-by-example
Here is an example with the tables persons, towns and countries, all
located in the database mydb. If you don't have a PMA_relation table,
create it as explained in the configuration section. Then create the
example tables:
CREATE TABLE REL_countries (
country_code char(1) NOT NULL default '',
description varchar(10) NOT NULL default '',
PRIMARY KEY (country_code)
) TYPE=MyISAM;
INSERT INTO REL_countries VALUES ('C', 'Canada');
CREATE TABLE REL_persons (
id tinyint(4) NOT NULL auto_increment,
person_name varchar(32) NOT NULL default '',
town_code varchar(5) default '0',
country_code char(1) NOT NULL default '',
PRIMARY KEY (id)
) TYPE=MyISAM;
INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
CREATE TABLE REL_towns (
town_code varchar(5) NOT NULL default '0',
description varchar(30) NOT NULL default '',
PRIMARY KEY (town_code)
) TYPE=MyISAM;
INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
INSERT INTO REL_towns VALUES ('M', 'Montr<74>al');
To setup appropriate links and display information:
* on table "REL_persons" click Structure, then Relation view
* in Links, for "town_code" choose "REL_towns->code"
* in Links, for "country_code" choose "REL_countries->country_code"
* on table "REL_towns" click Structure, then Relation view
* in "Choose field to display", choose "description"
* repeat the two previous steps for table "REL_countries"
Then test like this:
* Click on your db name in the left frame
* Choose "Query"
* Use tables: persons, towns, countries
* Click "Update query"
* In the fields row, choose persons.person_name and click the "Show"
tickbox
* Do the same for towns.description and countries.descriptions in
the other 2 columns
* Click "Update query" and you will see in the query box that the
correct joins have been generated
* Click "Submit query"
[6.7] How can I use the "display field" feature
Starting from the previous example, create the PMA_table_info as
explained in the configuration section, then browse your persons
table, and move the mouse over a town code or country code.
[6.8] How can I produce a PDF schema of my database
First you have to fill the "relation", "table_coords" and "pdf_pages"
configuration variables.
Then, think about your schema layout: which tables will go on which
pages.
* Click on your db name in the left frame
* Choose "Structure" in the navigation on top
* Choose "Edit PDF Pages" which should be somewhere at the bottom of
the page
* Enter the name for a first pdf page and submit
* Choose this page to edit
* Now add a table you want to show on this page and it's coordinates
and submit
First you will have to guess this coordinates of course, so just
expect to have an area of about 297 * 210 and put the tables
coordinates somewhere in there, you will be able to have a look at
what happened and change them later.
For example, x=100 and y=200 means that the table will be at 200
mm down and 100 mm right from the upper left corner.
Actually if you have a width of more than 300 or a height of more
than 200 than it will automatically be scaled but 300*100 is a
good start to have an idea of what coordinates to use.
* After every table you submitted you will have the possibility to
submit more tables
* When you have entered enough tables Click on your db name in the
left frame again
* Now, again at the bottom of the page you should be able to choose
"Display PDF schema"
For testing it might be useful to show the grid as well, so you
can see the coordinates used.
Maybe also choose color and submit.
* Save the file he will offer you to something like Schema.pdf
(Internet Explorer has some bug there which might make it offer it
without an extension. Under Windows it is important to have the
extension ".pdf", under other OSes you should be fine just saving
the file under the name it offers).
[6.9] phpMyAdmin is changing the type of one of my columns!
No, it's MySQL that is doing silent column type changing.
[6.10] My database has an underscore in it's name, and when I grant
privileges to a user for this database, a backslash is added before the
underscore
This is normal and means that the grant is done only for this
database. If there was no backslash, this would be a wildcard grant,
and the underscore would mean "any character". So, if the database
name is "john_db", the user would get rights to john1db, john2db...
instead of just john_db.
If you really want to grant using a wildcard, there is a dialog box "
Database (wildcards allowed)" for this.
[6.11] What is the curious symbol <20> in the table statistics
It means "average".
[6.12] I want to understand some Export options
"Complete inserts" adds the column names on every INSERT command, for
better documentation (but resulting file is bigger).
"Extended inserts" provides a shorter dump file by using only once the
INSERT verb and the table name.
"Enclose table and field names with backquotes" ensures that field and
table names formed with special characters are protected.
[6.13] I would like to create a database with a dot in its name
This is a bad idea, because in MySQL the syntax "database.table" is
the normal way to reference a database and table name. Worse, MySQL
will usually let you create a database with a dot, but then you cannot
work with it, nor delete it.
[6.14] How do I set up the SQL validator
To use it, you need a very recent version of PHP, 4.3.0 recommended,
with XML, PCRE and PEAR support. On your system command line, run
"pear install Net_Socket Net_URL HTTP_Request Mail_Mime Net_DIME SOAP"
to get the nessecary PEAR modules for usage.
If you use it, you should be aware that any SQL statement you submit
will be stored anonymously (database/table/column names, strings,
numbers replaced with generic values). The Mimer SQL Validator itself,
is <20> 2001 Upright Database Technology. We utilize it as free SOAP
service.
[6.15] I want to add a BLOB field and put an index on it, but MySQL says
"BLOB column '...' used in key specification without a key length"
The right way to do this, is to create the field without any indexes,
then display the table structure and use the "Create an index" dialog.
On this page, you will be able to choose your BLOB field, and set a
size to the index, which is the condition to create an index on a BLOB
field.
[6.16] How can I simply move in page with plenty editing fields
You can use Ctrl+arrows for moving on most pages with plenty editing
fields (table structure changes, row editing, etc.).
[6.17] Why is there checkbox called "Binary" when uplaoding file into
database?
It defines how data will be inserted into MySQL. When not checked, the
data from file will be treated as text, if charset conversion is
enabled (you are using utf-8 translation) charset of the text will be
converted according to it and could possibly be displayed as part of
update SQL after upload. When checked data will be inserted as
hexadecimal value and so will be in database exactly as in file. In
most cases you should keep it checked.
[7. phpMyAdmin project]
[7.1] I have found a bug. How do I inform developers
Our Bug Tracker is located at
http://sourceforge.net/projects/phpmyadmin/ under the Bugs section.
But please first discuss your bug with other users:
http://sourceforge.net/projects/phpmyadmin/ (and choose Forums)
[7.2] I want to translate the messages to a new language or upgrade an
existing language, where do I start
Always use the current cvs version of your language file. For a new
language, start from english-iso-8859-1.inc.php3. If you don't know
how to get the cvs version, please ask one of the developers.
Please note that we try not to use html entities like &eacute; in the
translations, since we define the right character set in the file.
With html entities, the text on buttons would not display correctly.
You can then put your translations, as a zip file to avoid losing
special characters, on the sourceforge.net translation tracker.
It would be a good idea to subscribe to the phpmyadmin-translators
mailing list, because this is where we ask for translations of new
messages.
[7.3] I would like to help out with the development of phpMyAdmin. How
should I proceed
The following method is preferred for new developers:
1. fetch the current CVS tree over anonymous CVS:
cvs
-d:pserver:anonymous@cvs.phpmyadmin.sourceforge.net:/cvsroot/phpmy
admin login
[Password: simply press the Enter key]
cvs -z3
-d:pserver:anonymous@cvs.phpmyadmin.sourceforge.net:/cvsroot/phpmy
admin checkout phpMyAdmin
[This will create a new sub-directory named phpMyAdmin]
2. add your stuff
3. put the modified files (tar'ed and gzip'ed) inside the patch
tracker of the phpMyAdmin SourceForge account.
Write access to the CVS tree is granted only to experienced developers
who have already contributed something useful to phpMyAdmin.
Also, have a look at the Developers section.
Developers Information
phpMyAdmin is Open Source, so you're invited to contribute to it. Many
great features have been written by other people and you too can help
to make phpMyAdmin a useful tool.
If you're planning to contribute source, please read the following
information:
* All files include header.inc.php3 (layout),
libraries/common.lib.php3 (common functions) and config.inc.php3.
All configuration data belongs in config.inc.php3. Please keep it
free from other code.
Commonly used functions should be added to
libraries/common.lib.php3 and more specific ones may be added
within a library stored into the libraries sub-directory.
* Obviously, you're free to use whatever coding style you want. But
please try to keep your code as simple as possible: beginners are
using phpMyAdmin as an example application.
As far as possible, we want the scripts to be XHTML1.0 and CSS2
compliant on one hand, they fit the PEAR coding standards on the
other hand. Please pay attention to this.
* Please try to keep up the file-naming conventions. Table-related
stuff goes to tbl_*.php3, db-related code to db_*.php3,
server-related tools to server_*.php3 and so on.
* Please don't use verbose strings in your code, instead add the
string (at least) to english-iso-8859-1.inc.php3 and print() it
out.
* If you want to be really helpful, write an entry for the
ChangeLog.
* The DBG extension (PHP Debugger DBG) is now supported by
phpMyAdmin for developers to better debug and profile their code.
Please see the $cfg['DBG']* configuration options for more
information.
This is in memorium of the Space Shuttle Columbia (STS-107) which
was lost during its re-entry into Earth's atmosphere and in memory
of the brave men and women who gave their lives for the people of
Earth.

Original Credits of Version 2.1.0
---------------------------------
This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
to create a web-based interface to MySQL using PHP3. Although I have not
used any of his source-code, there are some concepts I've borrowed from
him. phpMyAdmin was created because Peter told me he wasn't going to
further develop his (great) tool.
Thanks go to
- Amalesh Kempf <ak-lsml_at_living-source.com> who contributed the
code for the check when dropping a table or database. He also suggested
that you should be able to specify the primary key on tbl_create.php3. To
version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
well as a bug-report. Plus many smaller improvements.
- Jan Legenhausen <jan_at_nrw.net>: He made many of the changes that
were introduced in 1.3.0 (including quite significant ones like the
authentication). For 1.4.1 he enhanced the table-dump feature. Plus
bug-fixes and help.
- Marc Delisle <DelislMa_at_CollegeSherbrooke.qc.ca> made phpMyAdmin
language-independent by outsourcing the strings to a separate file. He
also contributed the French translation.
- Alexandr Bravo <abravo_at_hq.admiral.ru> who contributed
tbl_select.php3, a feature to display only some fields from a table.
- Chris Jackson <chrisj_at_ctel.net> added support for MySQL
functions in tbl_change.php3. He also added the
"Query by Example" feature in 2.0.
- Dave Walton <walton_at_nordicdms.com> added support for multiple
servers and is a regular contributor for bug-fixes.
- Gabriel Ash <ga244_at_is8.nyu.edu> contributed the random access
features for 2.0.6.
The following people have contributed minor changes, enhancements, bugfixes
or support for a new language:
Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
