Please have a look at our Link section on the official phpMyAdmin homepage for in-depth coverage of phpMyAdmin’s features and or interface.
Try to set the $cfg['OBGzip'] directive to false in your config.inc.php file and the zlib.output_compression directive to Off in your php configuration file.
You should first try the latest versions of Apache (and possibly MySQL). If your server keeps crashing, please ask for help in the various Apache support groups.
You just forgot to read the install.txt file from the PHP distribution. Have a look at the last message in this PHP bug report #12061 from the official PHP bug database.
This is a known problem with the PHP ISAPI filter: it’s not so stable. Please use instead the cookie authentication mode.
This seems to be a PWS bug. Filippo Simoncini found a workaround (at this time there is no better fix): remove or comment the DOCTYPE declarations (2 lines) from the scripts libraries/Header.class.php and index.php.
This feature is based on the gzencode() PHP function to be more independent of the platform (Unix/Windows, Safe Mode or not, and so on). So, you must have Zlib support (--with-zlib).
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:
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 Internet Explorer and SSL.
Since version 2.2.4, phpMyAdmin supports servers with open_basedir restrictions. However you need to create temporary directory and configure it as $cfg['TempDir']. The uploaded files will be moved there, and after execution of your SQL commands, removed.
The MySQL manual explains how to reset the permissions.
In previous MySQL versions, the User and Password``columns were named ``user and password. Please modify your column names to align with current standards.
Starting with version 2.7.0, the import engine has been re–written and these problems should not occur. If possible, upgrade your phpMyAdmin to the latest version to take advantage of the new import features.
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. There exist several workarounds if your upload is too big or your hosting provider is unwilling to change the settings:
Look at the $cfg['UploadDir'] feature. This allows one to upload a file to the server via scp, ftp, or your favorite file transfer method. PhpMyAdmin is then able to import the files from the temporary directory. More information is available in the Configuration of this document.
Using a utility (such as BigDump) to split the files before uploading. We cannot support this or any third party applications, but are aware of users having success with it.
If you have shell (command line) access, use MySQL to import the files directly. You can do this by issuing the “source” command from within MySQL:
source filename.sql;
Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can connect to your MySQL server using PHP’s classic MySQL extension as well as the improved MySQL extension (MySQLi) that is available in PHP 5.0. The latter one should be used unless you have a good reason not to do so. When compiling PHP, we strongly recommend that you manually link the MySQL extension of your choice to a MySQL client library of at least the same minor version since the one that is bundled with some PHP distributions is rather old and might cause problems see 1.17a I cannot connect to the MySQL server. It always returns the error message, “Client does not support authentication protocol requested by server; consider upgrading MySQL client”. MariaDB is also supported (versions 5.1 and 5.2 were tested).
Changed in version 3.5: Since phpMyAdmin 3.5 Drizzle is supported.
You tried to access MySQL with an old MySQL client library. The version of your MySQL client library can be checked in your phpinfo() output. In general, it should have at least the same minor version as your server - as mentioned in 1.17 Which MySQL versions does phpMyAdmin support?. This problem is generally caused by using MySQL version 4.1 or newer. MySQL changed the authentication hash and your PHP is trying to use the old method. The proper solution is to use the mysqli extension with the proper client library to match your MySQL installation. More information (and several workarounds) are located in the MySQL Documentation.
The TCPDF library we’re using for this feature requires some special files to use font faces. Please refers to the TCPDF manual to build these files.
To connect to a MySQL server, PHP needs a set of MySQL functions called “MySQL extension”. This extension may be part of the PHP distribution (compiled-in), otherwise it needs to be loaded dynamically. Its name is probably mysqli.so or php_mysqli.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.
There are currently two interfaces PHP provides as MySQL extensions - mysql and mysqli. The mysqli is tried first, because it’s the best one.
In php.ini, set mysql.max_links higher than 1.
This is most likely because in php.ini, your file_uploads parameter is not set to “on”.
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 your my.ini file that should be located in your Windows directory and add the following line to the group [mysqld]:
set-variable = 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';
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.
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 “IUSR_machine” from the list. Now set his permissions and it should work.
This was caused by a PHP bug that occur when GZIP output buffering is enabled. If you turn off it (by $cfg['OBGzip'] in config.inc.php), it should work. This bug will has been fixed in PHP 5.0.0.
This can happen due to a MySQL bug when having database / table names with upper case characters although lower_case_table_names is set to 1. To fix this, turn off this directive, convert all database and table names to lower case and turn it on again. Alternatively, there’s a bug-fix available starting with MySQL 3.23.56 / 4.0.11-gamma.
It is possible to configure Apache in such a way that PHP has problems interpreting .php files.
The problems occur when two different (and conflicting) set of directives are used:
SetOutputFilter PHP
SetInputFilter PHP
and
AddType application/x-httpd-php .php
In the case we saw, one set of directives was in /etc/httpd/conf/httpd.conf, while the other set was in /etc/httpd/conf/addon-modules/php.conf. The recommended way is with AddType, so just comment out the first set of lines and restart Apache:
#SetOutputFilter PHP
#SetInputFilter PHP
Yes.
Since release 4.1 phpMyAdmin supports only PHP 5.3 and newer. For PHP 5.2 you can use 4.0.x releases.
Yes. This procedure was tested with phpMyAdmin 2.6.1, PHP 4.3.9 in ISAPI mode under IIS 5.1.

Yes. Out of the box, you can use URL like http://server/phpMyAdmin/index.php?server=X&db=database&table=table&target=script. For server you use the server number which refers to the order of the server paragraph in config.inc.php. Table and script parts are optional. If you want http://server/phpMyAdmin/database[/table][/script] URL, you need to do some configuration. Following lines apply only for Apache web server. First make sure, that you have enabled some features within global configuration. You need Options FollowSymLinks and AllowOverride FileInfo enabled for directory where phpMyAdmin is installed and you need mod_rewrite to be enabled. Then you just need to create following .htaccess file in root folder of phpMyAdmin installation (don’t forget to change directory name inside of it):
RewriteEngine On
RewriteBase /path_to_phpMyAdmin
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&table=$2&target=$3 [R]
RewriteRule ^([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&target=$2 [R]
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)$ index.php?db=$1&table=$2 [R]
RewriteRule ^([a-zA-Z0-9_]+)$ index.php?db=$1 [R]
Yes. However you need to pass authentication variable to CGI using following rewrite rule:
RewriteEngine On
RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization},L]
There can be many explanations to this and a look at your server’s error log file might give a clue.
If your cluster consist of different architectures, PHP code used for encryption/decryption won’t work correct. This is caused by use of pack/unpack functions in code. Only solution is to use mcrypt extension which works fine in this case.
Yes but the default configuration values of Suhosin are known to cause problems with some operations, for example editing a table with many columns and no primary key or with textual primary key.
Suhosin configuration might lead to malfunction in some cases and it can not be fully avoided as phpMyAdmin is kind of application which needs to transfer big amounts of columns in single HTTP request, what is something what Suhosin tries to prevent. Generally all suhosin.request.*, suhosin.post.* and suhosin.get.* directives can have negative effect on phpMyAdmin usability. You can always find in your error logs which limit did cause dropping of variable, so you can diagnose the problem and adjust matching configuration variable.
The default values for most Suhosin configuration options will work in most scenarios, however you might want to adjust at least following parameters:
You can also disable the warning using the $cfg['SuhosinDisableWarning'].
Be sure that you have enabled SSLOptions and StdEnvVars in your Apache configuration.
To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers. Example from the Apache 2.2 documentation:
ProxyPass /mirror/foo/ http://backend.example.com/
ProxyPassReverse /mirror/foo/ http://backend.example.com/
ProxyPassReverseCookieDomain backend.example.com public.example.com
ProxyPassReverseCookiePath / /mirror/foo/
Note: if the backend url looks like http://host/~user/phpmyadmin, the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines. This is not specific to phpmyadmin, it’s just the behavior of Apache.
ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin
ProxyPassReverse /mirror/foo/ http://backend.example.com/%7Euser/phpmyadmin
ProxyPassReverseCookiePath /%7Euser/phpmyadmin /mirror/foo
The MySQL server’s privilege tables are not up to date, you need to run the mysql_upgrade command on the server.
You can add various rules to .htaccess to filter access based on user agent field. This is quite easy to circumvent, but could prevent at least some robots accessing your installation.
RewriteEngine on
# Allow only GET and POST verbs
RewriteCond %{REQUEST_METHOD} !^(GET|POST)$ [NC,OR]

Because your PHP’s memory_limit is too low; adjust it in php.ini.
Edit your config.inc.php file and ensure there is nothing (I.E. no blank lines, no spaces, no characters...) neither before the <?php tag at the beginning, neither after the ?> tag at the end. We also got a report from a user under IIS, that used a zipped distribution kit: the file libraries/Config.class.php contained an end-of-line character (hex 0A) at the end; removing this character cleared his errors.
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.
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:
Have also a look at the corresponding section of the MySQL documentation.
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 “b” or “alpha” it means you’re running a testing version of PHP. That’s not a so good idea, please upgrade to a plain revision.
Check the value you set for the $cfg['PmaAbsoluteUri'] directive in the phpMyAdmin configuration file.
When you are using a port on your localhost, which you redirect via port-forwarding to another host, MySQL is not resolving the localhost as expected. Erik Wasser explains: The solution is: if your host is “localhost” MySQL (the command line tool mysql as well) always tries to use the socket connection for speeding up things. And that doesn’t work in this configuration with port forwarding. If you enter “127.0.0.1” as hostname, everything is right and MySQL uses the TCP connection.
Themes are configured with $cfg['ThemePath'], $cfg['ThemeManager'] and $cfg['ThemeDefault']. Under $cfg['ThemePath'], you should not delete the directory pmahomme or its underlying structure, because this is the system theme used by phpMyAdmin. pmahomme contains all images and styles, for backwards compatibility and for all themes that would not include images or css-files. If $cfg['ThemeManager'] is enabled, you can select your favorite theme on the main page. Your selected theme will be stored in a cookie.
To create a theme:
In theme directory there is file info.inc.php which contains theme verbose name, theme generation and theme version. These versions and generations are enumerated from 1 and do not have any direct dependence on phpMyAdmin version. Themes within same generation should be backwards compatible - theme with version 2 should work in phpMyAdmin requiring version 1. Themes with different generation are incompatible.
If you do not want to use your own symbols and buttons, remove the directory “img” in “your_theme_name”. phpMyAdmin will use the default icons and buttons (from the system-theme pmahomme).
Here are a few points to check:
To be able to see a progress bar during your uploads, your server must have the APC extension, the uploadprogress one, or you must be running PHP 5.4.0 or higher. Moreover, the JSON extension has to be enabled in your PHP.
If using APC, you must set apc.rfc1867 to on in your php.ini.
If using PHP 5.4.0 or higher, you must set session.upload_progress.enabled to 1 in your php.ini. However, starting from phpMyAdmin version 4.0.4, session-based upload progress has been temporarily deactivated due to its problematic behavior.

This is related to the authentication mechanism (protocol) used by phpMyAdmin. To bypass this problem: just close all the opened browser windows and then go back to phpMyAdmin. You should be able to log in again.
Compressed dumps are built in memory and because of this are limited to php’s memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4 using $cfg['CompressOnFly'] (enabled by default). Zip exports can not be handled this way, so if you need Zip files for larger dump, you have to use another way.
This is an InnoDB bug, see <http://bugs.mysql.com/bug.php?id=21704>.
The problem is that older versions of mysqldump created 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 two dashes of the line or add a # before it: -- ------------------------------------------------------- or #---------------------------------------------------------
Please note that you should not use the separating string multiple times without any characters between them, or at the beginning/end of your table name. If you have to, think about using another TableSeparator or disabling that feature.

Your table neither have a primary key nor an unique one, so we must use a long expression to identify this row. This causes problems to parse_url function. The workaround is to create a primary or unique key.
Due to a surrounding form-container (for multi-row delete checkboxes), no nested forms can be put inside the table where phpMyAdmin displays the results. You can, however, use any form inside of a table if keep the parent form-container with the target to tbl_row_delete.php and just put your own input-elements inside. If you use a custom submit input field, the form will submit itself to the displaying page again, where you can validate the $HTTP_POST_VARS in a transformation. For a tutorial on how to effectively use transformations, see our Link section on the official phpMyAdmin-homepage.
When MySQL is running in ANSI-compatibility mode, there are some major differences in how SQL is structured (see <http://dev.mysql.com/doc/mysql/en/ansi-mode.html>). Most important of all, the quote-character (”) is interpreted as an identifier quote character and not as a string quote character, which makes many internal phpMyAdmin operations into invalid SQL statements. There is no workaround to this behaviour. News to this item will be posted in Bug report #1013.
Please make sure that your table has a primary key, so that phpMyAdmin can use it for the Edit and Delete links.
phpMyAdmin uses a quick method to get the row count, and this method only returns an approximate count in the case of InnoDB tables. See $cfg['MaxExactCount'] for a way to modify those results, but this could have a serious impact on performance. However, one can easily replace the approximate row count with exact count by simply clicking on the approximate count. This can also be done for all tables at once by clicking on the rows sum displayed at the bottom.
The tests I have made with MySQL 5.1.49 shows that the API does not accept this syntax for the USE command.
This has been a known limitation of phpMyAdmin since the beginning and it’s not likely to be solved in the future.
There is no reliable way to differentiate tables in CSV format. For the time being, you will have to break apart CSV files containing multiple tables.
Currently, the import type-detection system can only assign these MySQL types to columns. In future, more will likely be added but for the time being you will have to edit the structure to your liking post-import. Also, you should note the fact that phpMyAdmin will use the size of the largest item in any given column as the column size for the appropriate type. If you know you will be adding larger items to that column then you should manually adjust the column sizes accordingly. This is done for the sake of efficiency.
At some point, the character set used to store bookmark content has changed. It’s better to recreate your bookmark from the newer phpMyAdmin version.
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.

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 or cookie authentication features.
Suggestions:
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.
This could happen for several reasons:
Starting with 2.2.5, in the user management page, you can enter a wildcard database name for a user (for example “joe%”), 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).
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',
);
This happens if you are using a URL to start phpMyAdmin which is different than the one set in your $cfg['PmaAbsoluteUri']. For example, a missing “www”, or entering with an IP address while a domain name is defined in the config file.
When starting phpMyAdmin, you can use the db, pma_username, pma_password and server parameters. This last one can contain either the numeric host index (from $i of the configuration file) or one of the host names present in the configuration file. Using pma_username and pma_password has been tested along with the usage of ‘cookie’ auth_type.
We could reproduce this problem only under Win98/98SE. Testing under WinNT4 or Win2K, we could easily create more than 60 columns. A workaround is to create a smaller number of columns, then come back to your table properties and add the other columns.
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.
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.
MS Internet Explorer seems to be really buggy about cookies, at least till version 6.
Upgrade to at least Internet Explorer 5.5 SP2.
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 length 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.
Some browsers support right-clicking into the frame you want to refresh, just do this in the right frame.
Looks like a Mozilla bug: 0.9.6 was OK. We will keep an eye on future Mozilla versions.
This is a Mozilla bug (see bug #26882 at BugZilla).
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.
Please ensure that you have set your browser’s character set 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.
This issue has been reported by a Mac OS X user, who adds that Chimera, Netscape and Mozilla do not have this problem.
This is a bug in Internet Explorer, other browsers do not behave this way.
Please upgrade to Opera7 at least.
Please upgrade to at least version 1.2.3.
Please check the following points:
Many users have confirmed that the Tabbrowser Extensions plugin they installed in their Firefox is causing the problem.
This happens only when both of these conditions are met: using the http authentication mode and register_globals being set to On on the server. It seems to be a browser-specific problem; meanwhile use the cookie authentication mode.
Issues have been reported with some combinations of browser extensions. To troubleshoot, disable all extensions then clear your browser cache to see if the problem goes away.
Examine the SQL error with care. Often the problem is caused by specifying a wrong column-type. Common errors include:
Also, look at the syntax chapter in the MySQL manual to confirm that your syntax is correct.
This is the way to create a multi-columns 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.
Since version 2.2.3, you have a checkbox for each column that can be null. Before 2.2.3, you had to enter “null”, without the quotes, as the column’s value. Since version 2.5.5, you have to use the checkbox to get a real NULL value, so if you enter “NULL” this means you want a literal NULL in the column, and not a NULL value (this works in PHP4).
Click on a database or table name in the navigation panel, 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.
Click on a database name in the navigation panel, the properties will be displayed. Select “Import” from the list of tabs in the right–hand frame (or “SQL” if your phpMyAdmin version is previous to 2.7.0). In the “Location of the text file” section, type in the path to your dump filename, or use the Browse button. Then click Go. With version 2.7.0, the import engine has been re–written, if possible it is suggested that you upgrade to take advantage of the new features. For additional help on this subject, look for the word “upload” in this document.
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', 'Montréal');
To setup appropriate links and display information:
Then test like this:
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. See also 6.21 In edit/insert mode, how can I see a list of possible values for a column, based on some foreign table? for an additional feature that “display column” enables: drop-down list of possible values.
First the configuration variables “relation”, “table_coords” and “pdf_pages” have to be filled in. Then you need to think about your schema layout. Which tables will go on which pages?
No, it’s MySQL that is doing silent column type changing.
If you do not put a backslash before the underscore, this is a wildcard grant, and the underscore means “any character”. So, if the database name is “john_db”, the user would get rights to john1db, john2db ... If you put a backslash before the underscore, it means that the database name will have a real underscore.
It means “average”.
Structure:
Data:
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.
The right way to do this, is to create the column 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 column, and set a size to the index, which is the condition to create an index on a BLOB column.
You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages with many editing fields (table structure changes, row editing, etc.).
Slow down :). Defining mimetypes is of no use, if you can’t put transformations on them. Otherwise you could just put a comment on the column. Because entering your own mimetype will cause serious syntax checking issues and validation, this introduces a high-risk false- user-input situation. Instead you have to initialize mimetypes using functions or empty mimetype definitions.
Plus, you have a whole overview of available mimetypes. Who knows all those mimetypes by heart so he/she can enter it at will?
Any query you have executed can be stored as a bookmark on the page where the results are displayed. You will find a button labeled ‘Bookmark this query’ just at the end of the page. As soon as you have stored a bookmark, it is related to the database you run the query on. You can now access a bookmark dropdown on each page, the query box appears on for that database.
You can also have, inside the query, a placeholder for a variable. This is done by inserting into the query a SQL comment between /* and */. Inside the comment, the special string [VARIABLE] is used. Be aware that the whole query minus the SQL comment must be valid by itself, otherwise you won’t be able to store it as a bookmark.
When you execute the bookmark, everything typed into the value input box on the query box page will replace the string /*[VARIABLE]*/ in your stored query.
Also remember, that everything else inside the /*[VARIABLE]*/ string for your query will remain the way it is, but will be stripped of the /**/ chars. So you can use:
/*, [VARIABLE] AS myname */
which will be expanded to
, VARIABLE as myname
in your query, where VARIABLE is the string you entered in the input box. If an empty string is provided, no replacements are made.
A more complex example. Say you have stored this query:
SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */
Say, you now enter “phpMyAdmin” as the variable for the stored query, the full query will be:
SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'
You can use multiple occurrences of /*[VARIABLE]*/ in a single query (that is, multiple occurrences of the same variable).
NOTE THE ABSENCE OF SPACES inside the /**/ construct. Any spaces inserted there will be later also inserted as spaces in your query and may lead to unexpected results especially when using the variable expansion inside of a “LIKE ‘’” expression.
Your initial query which is going to be stored as a bookmark has to yield at least one result row so you can store the bookmark. You may have that to work around using well positioned /**/ comments.
You can simply include table in your LATEX documents, minimal sample document should look like following one (assuming you have table exported in file table.tex):
\documentclass{article} % or any class you want
\usepackage{longtable} % for displaying table
\begin{document} % start of document
\include{table} % including exported table
\end{document} % end of document
You have one of these global privileges: CREATE TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also enable users to see all the database names. So if your users do not need those privileges, you can remove them and their databases list will shorten.

You have to setup appropriate links between the tables, and also setup the “display column” in the foreign table. See 6.6 How can I use the relation table in Query-by-example? for an example. Then, if there are 100 values or less in the foreign table, a drop-down list of values will be available. You will see two lists of values, the first list containing the key and the display column, the second list containing the display column and the key. The reason for this is to be able to type the first letter of either the key or the display column. For 100 values or more, a distinct window will appear, to browse foreign key values and choose one. To change the default limit of 100, see $cfg['ForeignKeyMaxLimit'].
Yes. If a bookmark has the same label as a table name and it’s not a public bookmark, it will be executed.
You can use CSV for Microsoft Excel, which works out of the box.
Changed in version 3.4.5: Since phpMyAdmin 3.4.5 support for direct export to Microsoft Excel version 97 and newer was dropped.
Automatic migration of a table’s pmadb-style column comments to the native ones is done whenever you enter Structure page for this table.
Click the first row of the range, hold the shift key and click the last row of the range. This works everywhere you see rows, for example in Browse mode or on the Structure page.
In all places where phpMyAdmin accepts format strings, you can use @VARIABLE@ expansion and strftime format strings. The expanded variables depend on a context (for example, if you haven’t chosen a table, you can not get the table name), but the following variables can be used:
By clicking on the button ‘toggle scratchboard’ on the page where you edit x/y coordinates of those elements you can activate a scratchboard where all your elements are placed. By clicking on an element, you can move them around in the pre-defined area and the x/y coordinates will get updated dynamically. Likewise, when entering a new position directly into the input field, the new position in the scratchboard changes after your cursor leaves the input field.
You have to click on the ‘OK’-button below the tables to save the new positions. If you want to place a new element, first add it to the table of elements and then you can drag the new element around.
By changing the paper size and the orientation you can change the size of the scratchboard as well. You can do so by just changing the dropdown field below, and the scratchboard will resize automatically, without interfering with the current placement of the elements.
If ever an element gets out of range you can either enlarge the paper size or click on the ‘reset’ button to place all elements below each other.
Not every table can be put to the chart. Only tables with one, two or three columns can be visualised as a chart. Moreover the table must be in a special format for chart script to understand it. Currently supported formats can be found in the wiki.
An ESRI Shapefile is actually a set of several files, where .shp file contains geometry data and .dbf file contains data related to those geometry data. To read data from .dbf file you need to have PHP compiled with the dBase extension (–enable-dbase). Otherwise only geometry data will be imported.
To upload these set of files you can use either of the following methods:
Configure upload directory with $cfg['UploadDir'], upload both .shp and .dbf files with the same filename and chose the .shp file from the import page.
Create a Zip archive with .shp and .dbf files and import it. For this to work, you need to set $cfg['TempDir'] to a place where the web server user can write (for example './tmp').
To create the temporary directory on a UNIX-based system, you can do:
cd phpMyAdmin
mkdir tmp
chmod o+rwx tmp
To select relation, click: The display column is shown in pink. To set/unset a column as the display column, click the “Choose column to display” icon, then click on the appropriate column name.
The Zoom search feature is an alternative to table search feature. It allows you to explore a table by representing its data in a scatter plot. You can locate this feature by selecting a table and clicking the Search tab. One of the sub-tabs in the Table Search page is Zoom Search.
Consider the table REL_persons in 6.6 How can I use the relation table in Query-by-example? for an example. To use zoom search, two columns need to be selected, for example, id and town_code. The id values will be represented on one axis and town_code values on the other axis. Each row will be represented as a point in a scatter plot based on its id and town_code. You can include two additional search criteria apart from the two fields to display.
You can choose which field should be displayed as label for each point. If a display column has been set for the table (see 6.7 How can I use the “display column” feature?), it is taken as the label unless you specify otherwise. You can also select the maximum number of rows you want to be displayed in the plot by specifing it in the ‘Max rows to plot’ field. Once you have decided over your criteria, click ‘Go’ to display the plot.
After the plot is generated, you can use the mousewheel to zoom in and out of the plot. In addition, panning feature is enabled to navigate through the plot. You can zoom-in to a certail level of detail and use panning to locate your area of interest. Clicking on a point opens a dialogue box, displaying field values of the data row represented by the point. You can edit the values if required and click on submit to issue an update query. Basic instructions on how to use can be viewed by clicking the ‘How to use?’ link located just above the plot.
Selecting the name of the column within the browse table header cell for copying is difficult, as the columns support reordering by dragging the header cells as well as sorting by clicking on the linked column name. To copy a column name, double-click on the empty area next to the column name, when the tooltip tells you to do so. This will show you an input box with the column name. You may right-click the column name within this input box to copy it to your clipboard.
Favorite Tables feature is very much similar to Recent Tables feature. It allows you to add a shortcut for the frequently used tables of any database in the navigation panel . You can easily navigate to any table in the list by simply choosing it from the list. These tables are stored in your browser’s local storage if you have not configured your phpMyAdmin Configuration Storage. Otherwise these entries are stored in phpMyAdmin Configuration Storage.
IMPORTANT: In absence of phpMyAdmin Configuration Storage, your Favorite tables may be different in different browsers based on your different selections in them.
To add a table to Favorite list simply click on the Gray star in front of a table name in the list of tables of a Database and wait until it turns to Yellow. To remove a table from list, simply click on the Yellow star and wait until it turns Gray again.
Using $cfg['NumFavoriteTables'] in your config.inc.php file, you can define the maximum number of favorite tables shown in the navigation panel. Its default value is 10.
With the help of range search feature, one can specify a range of values for particular column(s) while performing search operation on a table from the Search tab.
To use this feature simply click on the BETWEEN or NOT BETWEEN operators from the operator select list in front of the column name. On choosing one of the above options, a dialog box will show up asking for the Minimum and Maximum value for that column. Only the specified range of values will be included in case of BETWEEN and excluded in case of NOT BETWEEN from the final results.
Note: The Range search feature will work only Numeric and Date data type columns.
As the name suggests, the Central columns feature enables to maintain a central list of columns per database to avoid similar name for the same data element and bring consistency of data type for the same data element. You can use the central list of columns to add an element to any table structure in that database which will save from writing similar column name and column definition.
To add a column to central list, go to table structure page, check the columns you want to include and then simply click on “Add to central columns”. If you want to add all unique columns from more than one table from a database then go to database structure page, check the tables you want to include and then select “Add columns to central list”.
To remove a column from central list, go to Table structure page, check the columns you want to remove and then simply click on “Remove from central columns”. If you want to remove all columns from more than one tables from a database then go to database structure page, check the tables you want to include and then select “Remove columns from central list”.
To view and manage the central list, select the database you want to manage central columns for then from the top menu click on “Central columns”. You will be taken to a page where you will have options to edit, delete or add new columns to central list.
Improve table structure feature helps to bring the table structure upto Third Normal Form. A wizard is presented to user which asks questions about the elements during the various steps for normalization and a new structure is proposed accordingly to bring the table into the First/Second/Third Normal form. On startup of the wizard, user gets to select upto what normal form they want to normalize the table structure.
Here is an example table which you can use to test all of the three First, Second and Third Normal From.
CREATE TABLE `VetOffice` (
`petName` varchar(64) NOT NULL,
`petBreed` varchar(64) NOT NULL,
`petType` varchar(64) NOT NULL,
`petDOB` date NOT NULL,
`ownerLastName` varchar(64) NOT NULL,
`ownerFirstName` varchar(64) NOT NULL,
`ownerPhone1` int(12) NOT NULL,
`ownerPhone2` int(12) NOT NULL,
`ownerEmail` varchar(64) NOT NULL,
);
The above table is not in First normal Form as no primary key exists. Primary key is supposed to be (petName,`ownerLastName`,`ownerFirstName`) . If the primary key is chosen as suggested the resultant table won’t be in Second as well as Third Normal form as the following dependencies exists.
(OwnerLastName, OwnerFirstName) -> OwnerEmail
(OwnerLastName, OwnerFirstName) -> OwnerPhone
PetBreed -> PetType
Which says, OwnerEmail depends on OwnerLastName and OwnerFirstName. OwnerPhone depends on OwnerLastName and OwnerFirstName. PetType depends on PetBreed.

If you use Apache web server, phpMyAdmin exports information about authentication to the Apache environment and it can be used in Apache logs. Currently there are two variables available:
LogFormat directive for Apache can look like following:
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %{userID}n %{userStatus}n" pma_combined
You can then use any log analyzing tools to detect possible break-in attempts.
