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);
* 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 and alter tables
* 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 (*) and import data to CSV values
* administer multiple servers and single databases
* check referential integrity
* communicate in more than 38 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.
Warning for Mac users: php seems not to like Mac end of lines
character ("\r") and Stuffit unstuffs with Mac formats, of course.
So you'll have to resave as in Bbedit to unix style ALL phpMyAdmin
scripts before uploading them to your server.
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. Use 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.
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
$cfgPmaAbsoluteUri. Have a look at [29]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 [30]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!
* Http and cookie authentication modes are secure: the MySQL
password does not need to be set in the phpMyAdmin configuration
file. (except for the "controluser" -see the Configuration
section-).
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 $cfgServers[$i]['controluser']&
$cfgServers[$i]['controlpass'] settings.
This example assumes you want to use pma as the controluser and
pmapass as the controlpass:
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 bookmark feature:
GRANT SELECT, INSERT, DELETE ON <bookmark_db>.<bookmark_table> TO
'pma'@'localhost';
* Then each of the true users should be granted of a set of
privileges on a set of perticular databases but shouldn't have any
global privileges. 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 $cfgServers 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 $cfgServers[$i]['user'] and $cfgServers[$i]['password']
fields.
But you don't need to setup a "controluser" here: using the
$cfgServers[$i]['only_db'] might be enough.
In the ISP FAQ section, there is an entry explaining how to
protect your configuration file.

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.
$cfgPmaAbsoluteUri 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/.
Don't forget the slash at the end of your url.
This setting can be dynamically completed. For example, you can
try to use such a kind of code:
$cfgPmaAbsoluteUri = (!empty($HTTPS) ? 'https' : 'http') . '://'
. $SERVER_NAME . (!empty($SERVER_PORT) ? ':' . $SERVER_PORT
: '')
. substr($SCRIPT_NAME, 0, strrpos($SCRIPT_NAME, '/')+1);
$cfgServers array
Since version 1.4.2, phpMyAdmin supports the administration of
multiple MySQL servers. Therefore, a $cfgServers-array has been
added which contains the login information for the different
servers. The first $cfgServers[$i]['host'] contains the
hostname of the first server, the second
$cfgServers[$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 $cfgServer-entries.
$cfgServers[$i]['host'] string
The hostname of your $i-th MySQL-server. E.g. localhost.
$cfgServers[$i]['port'] string
The port-number of your $i-th MySQL-server. Default is 3306
(leave blank).
$cfgServers[$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.
$cfgServers[$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.
$cfgServers[$i]['controluser'] string
$cfgServers[$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 [39]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".
$cfgServers[$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.
$cfgServers[$i]['user'] string
$cfgServers[$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.
$cfgServers[$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.
$cfgServers[$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.
$cfgServers[$i]['bookmarkdb'] string
$cfgServers[$i]['bookmarktable'] string
Since release 2.2.0 phpMyAdmin allows to bookmark queries. This
can be useful for queries you often run.
To use this functionality you have to:
+ create a table following this scheme:
CREATE TABLE 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)
);
+ then complete the two variables $cfgServers[$i]['bookmarkdb']
and $cfgServers[$i]['bookmarktable'] with the database and
table names you've choosen so phpMyAdmin will be able to find
the bookmarks.
Note that controluser must have SELECT, INSERT and DELETE
privileges on the bookmark table. Here is a query to set up
those privileges (using "pma" as the controluser:
GRANT SELECT,INSERT,DELETE ON <bookmarkdb>.<bookmarktable> to
'pma'@localhost;
$cfgServers[$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 src table, the data
values that point to the dest table;
+ display links on the table properties page, to check
referential integrity (display missing foreign keys) for each
described key.
The keys can be numeric or character.
To use this functionality you have to:
+ create in the same database a table (for example 'relation')
following this scheme:
CREATE TABLE `relation` (
`src_table` varchar(32) NOT NULL default '',
`src_column` varchar(32) NOT NULL default '',
`dest_table` varchar(32) NOT NULL default '',
`dest_column` varchar(32) NOT NULL default '',
PRIMARY KEY (`src_table`,`src_column`)
) TYPE=MyISAM COMMENT='Table Relation';
+ put the relation table name in $cfgServers[$i]['relation']
+ then manually fill the relation table with information about
the keys.
$cfgServerDefault integer
If you have more than one server configured, you can set
$cfgServerDefault 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, $cfgServerDefault MUST
be set to that server.
$cfgOBGzip boolean
Defines whether to use gzip output buffering for increased
speed in HTTP transfers.
$cfgPersistentConnections boolean
Whether persistent connections should be used or not
(mysql_connect or mysql_pconnect).
$cfgExecTimeLimit 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.
$cfgSkipLockedTables boolean
Mark used tables and make it possible to show databases with
locked tables (since 3.23.30).
$cfgShowSQL boolean
Defines whether sql-queries generated by phpMyAdmin should be
displayed or not.
$cfgAllowUserDropDatabase 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.
$cfgConfirm boolean
Whether a warning ("Are your really sure..") should be
displayed when you're about to loose data.
$cfgShowTooltip boolean
Defines whether to display table comment as tooltip in left
frame or not.
$cfgLeftFrameLight boolean
Defines whether to use select-based menu and display only the
current tables in the left frame (smaller page).
$cfgShowMysqlInfo boolean
$cfgShowMysqlVars boolean
$cfgShowPhpInfo boolean
$cfgShowChgPassword 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.
$cfgLoginCookieRecall boolean
Define whether the previous login should be recalled or not in
cookie authentication mode.
$cfgShowStats 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.
$cfgShowBlob boolean
Defines whether BLOB fields are shown when browsing a table's
content or not.
$cfgNavigationBarIconic boolean
Defines whether navigation bar buttons contain text or symbols
only.
$cfgShowAll boolean
Defines whether an user should be displayed a "show all
(records)" button in browse mode or not.
$cfgMaxRows integer
Number of rows displayed when browsing a resultset. If the
resultset contains more rows, Previous/Next links will be
shown.
$cfgOrder 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.
$cfgProtectBinary 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.
$cfgShowFunctionFields boolean
Defines whether MySQL functions fields should be displayed or
not in edit/insert mode.
$cfgZipDump boolean
$cfgGZipDump boolean
$cfgBZipDump boolean
Defines whether to allow the use of zip/gzip/bzip compression
when creating a dump file or not.
$cfgManualBaseShort string
If set to an URL which points to the MySQL documentation (on
short pages), appropriate help links are generated.
$cfgDefaultLang 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.
$cfgLang string
Force: always use this language (must be defined in the
select_lang.inc.php3 script).
$cfgLeftWidth integer
Left frame width in pixel.
$cfgLeftBgColor string [HTML color]
$cfgRightBgColor string [HTML color]
The background colors (HTML) used for both the frames.
$cfgLeftPointerColor string [HTML color]
The color (HTML) used for the pointer in the left frame (does
not work with NS4).
$cfgBorder integer
The size of a table's border.
$cfgThBgcolor string [HTML color]
The color (HTML) used for table headers.
$cfgBgcolorOne string [HTML color]
The color (HTML) #1 for table rows.
$cfgBgcolorTwo string [HTML color]
The color (HTML) #2 for table rows.
$cfgBrowsePointerColor string [HTML color]
$cfgBrowseMarkerColor string [HTML color]
The colors (HTML) used for the pointer and the marker in browse
mode (does not work with NS4).
The former feature enlights the row you're mouse is passing
over and the latter lets you visually mark/unmark rows by
clicking on them.
You can disable both of these features by emptying the
convenient directive.
$cfgTextareaCols integer
$cfgTextareaRows integer
Number of columns and rows for the textareas.
$cfgLimitChars 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.
$cfgModifyDeleteAtLeft boolean
$cfgModifyDeleteAtRight 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.
$cfgDefaultDisplay string
There are 2 display modes: horizontal and vertical. Define
which one is displayed by default.
$cfgRepeatCells integer
Repeat the headers every X cells, or 0 to deactivate.
$cfgColumnTypes array
All possible types of a MySQL column. In most cases you don't
need to edit this.
$cfgAttributeTypes array
Possible attributes for fields. In most cases you don't need to
edit this.
$cfgFunctions array
A list of functions MySQL supports. In most cases you don't
need to edit this.

FAQ - Frequently Asked Questions
[Server]
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 $cfgOBGzip directive to FALSE in your config.inc.php or
.php3 file and the zlib.output_compression directive to Off in your
php configuration file.
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.
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 [48]bug report
from the official php bug database.
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 [49]this thread from the
phpWizard forum.
Please use instead the cookie authentication mode.
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 (3 lines) from the scripts header.inc.php3, index.php3,
left.php3 and libraries/common.lib.php3.
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).
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
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 [50]php's bug tracking
system for more details). The problem is that the bugged package is
still available though it was corrected (see [51]redhat's bugzilla for
more details).
So please download [52]the fixed package (4.0.4pl1-9) and the problem
should go away.
And that fixes the \r\n problem with file uploads!
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.
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.
I have lost my MySQL root password, what can I do?
The MySql manual explains how to [53]reset the permissions.
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.
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.
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.
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.
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 an alpha release and should be
used for test purposes only!
I'm running MySQL 4.0.1 on a Windows NT machine. Each time I create a
table the table name is changed to lowercase.
This seems to be a bug of MySQL 4.0.1 because it also appears when
using the MySQL commandline. Currently we only know about its
appearance on Windows NT systems, but it is possible that it appears
on other systems, too.
If you encounter this bug together with another OS and/or MySQL
version or you know how to work around it, please post a message into
[54]our bug tracker at SourceForge.
[Configuration]
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.
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.
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 [55]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: $cfgServers[$i]['socket'] = '/tmp/mysql.sock';
Have also a look at the [56]corresponding section of the MySQL
documentation.
Nothing is displayed by my browser when I try to run phpMyAdmin, what
can I do?
Try to set the $cfgOBGZip 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.
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 $cfgPmaAbsoluteUri directive in the
phpMyAdmin configuration file.
[Known limitations]
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.
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.
[ISPs, multi-user installations ]
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 authentication. See the install section
on "Using http authentication".
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.
I get errors about not being able to include a file in /lang
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.
phpMyAdmin always gives "Access denied" when using http
authentication.
This could happen for several reasons:
* $cfgServers[$i]['controluser'] and/or
$cfgServers[$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.
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).
[Browsers or client OS]
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.
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.
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.
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 works!
In Internet Explorer 5.0, I get Javascript errors when browsing my
rows.
Upgrade to at least Internet Explorer 5.5SP2.
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.
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.
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.
[Using phpMyAdmin]
I can't insert new rows into a table - MySQL brings up a SQL-error.
Examine the SQL error with care. I've found that many programmers
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.
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.
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.
[phpMyAdmin project]
I have found a bug. How do I inform developers?
Our Bug Tracker is located at
[57]http://sourceforge.net/projects/phpmyadmin/ under the Bugs
section.
But please first discuss your bug with other users:
[58]http://sourceforge.net/projects/phpmyadmin/ (and choose Forums)
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.inc.php3. If you don't know how to get
the cvs version, please ask one of the developers.
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.
I would like to help out with the development of phpMyAdmin. How
should I proceed?
The following method is preferred for new developers:
* 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]
* add your stuff
* put the modified files (tar'ed and gzip'ed) inside the patch
tracker of the [59]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 [60]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 [69]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 and so on.
* Please don't use verbose strings in your code, instead add the
string (at least) to english.inc.php3 and print() it out.
* If you want to be really helpful, write an entry for the
ChangeLog.
IMPORTANT: With 1.4.1, development has switched to CVS. The following
method is preferred for new developers:
* 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]
* add your stuff
* put the modified files (tar'ed and gzip'ed) inside the patch
tracker of the phpMyAdmin SourceForge account
([70]http://sourceforge.net/projects/phpmyadmin/)
Write access to the CVS tree is granted only to developers who have
already contributed something useful to phpMyAdmin. If you're
interested in that, please contact us using the phpmyadmin-devel
mailing list.

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,
G. Wieggers.
And thanks to everyone else who sent me email with suggestions, bug-reports
and or just some feedback.
