81 <!-- INTRODUCTION -->
84 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
85 a single database. To accomplish the latter you'll need a properly set up
86 MySQL user who can read/write only the desired database. It's up to you to
87 look up the appropriate part in the MySQL manual.

133 <p> Many people have difficulty
134 understanding the concept of user management with regards to phpMyAdmin. When
135 a user logs in to phpMyAdmin, that username and password are passed directly
136 to MySQL. phpMyAdmin does no account management on its own (other than
137 allowing one to manipulate the MySQL user account information); all users
138 must be valid MySQL users.</p>
147 <!-- INSTALLATION -->
155 </ol>
158 phpMyAdmin does not apply any special security methods to the MySQL database
159 server. It is still the system administrator's job to grant permissions on
161 be used for this.
162 </p>
170 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
171 before uploading them to your server, as PHP seems not to like
176 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
177 Downloads page. Some kits contain only the English messages,
178 others contain all languages in UTF-8 format (this should be fine
179 in most situations), others contain all
180 languages and all character sets. We'll assume you chose a kit whose
182 </li>
183 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
185 document root. If you don't have direct access to your document root,
186 put the files in a directory on your local machine, and, after step 4,
187 transfer the directory on your web server using, for example, ftp.</li>
188 <li>Ensure that all the scripts have the appropriate owner (if PHP is
189 running in safe mode, having some scripts with an owner different
190 from the owner of other scripts will be a
195 <li>Now you must configure your installation. There are two methods that
196 can be used. Traditionally, users have hand-edited a copy of
198 provided for those who prefer a graphical installation. Creating a
200 still a quick way to get started and needed for some advanced features.
201 <ul><li>To manually create the file, simply use your text editor to
204 file) in the main (top-level) phpMyAdmin directory (the one
208 default value is okay for a particular setting, there is no
210 few directives to get going, a simple configuration may look
211 like this:
212 <pre>
213 <?php
214 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
216 $i=0;
217 $i++;
218 $cfg['Servers'][$i]['auth_type'] = 'cookie';
219 ?>
220 </pre>
221 Or, if you prefer to not be prompted every time you log in:
222 <pre>
223 <?php
225 $i=0;
226 $i++;
227 $cfg['Servers'][$i]['user'] = 'root';
228 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
229 ?>
230 </pre>
231 For a full explanation of possible configuration values, see the
237 directory. This is a security measure. On a Linux/Unix system you
238 can use the following commands:
239 <pre>
240 cd phpMyAdmin
241 mkdir config # create directory for saving
242 chmod o+rw config # give it world writable permissions
243 </pre>
244 And to edit an existing configuration, copy it over first:
245 <pre>
246 cp config.inc.php config/ # copy current configuration for editing
247 chmod o+w config/config.inc.php # give it world writable permissions
248 </pre>
249 On other platforms, simply create the folder and ensure that your
258 the webserver does not have the proper permissions you may see the
260 config/</tt> directory exists and has the proper permissions -
262 and upload (via FTP or some similar means) to the proper location.<br /><br />
264 Once the file has been saved, it must be moved out of the <tt>
265 config/</tt> directory and the permissions must be reset, again
266 as a security measure:
267 <pre>
268 mv config/config.inc.php . # move file to current directory
269 chmod o-rw config.inc.php # remove world read and write permissions
270 </pre>
271 Now the file is ready to be used. You can choose to review or edit
272 the file with your favorite editor, if you prefer to set some
273 advanced options which the setup script does not provide.</li></ul></li>
274 <li>If you are using the
276 protect the phpMyAdmin installation directory because using
277 config does not require a user to
278 enter a password to access the phpMyAdmin installation. Use of an alternate
279 authentication method is recommended, for example with
287 in your browser. phpMyAdmin should now display a welcome screen
288 and your databases, or a login dialog if using
290 authentication mode.</li>
292 webserver configuration. For Apache you can use supplied .htaccess file
293 in that folder, for other webservers, you should configure this yourself.
294 Such configuration prevents from possible path exposure and cross side
295 scripting vulnerabilities that might happen to be found in that code.</li>
296 </ol>
300 <p> For a whole set of new features (bookmarks, comments,
303 transformation, etc.) you need to create a set of special tables. Those
304 tables can be located in your own database, or in a central database for a
305 multi-user installation (this database would then be accessed by the
306 controluser, so no other user should have rights to it).</p>
315 installation.</p>
320 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
321 that you may need special (administrator) privileges to create the database
322 and tables, and that the script may need some tuning, depending on the
323 database name.</p>
328 section</a>. You will also need to have a controluser with the proper rights
335 unpacked one. Configuration files from very old versions (2.3.0 or before) may
336 require some tweaking as some options have been changed or removed.
338 statement that you might find near the end of your configuration file.</p>
342 is version-specific.</p>
345 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
346 you should run the SQL script found in
353 where you want to give users access to their own database and don't want
354 them to play around with others.<br />
355 Nevertheless be aware that MS Internet Explorer seems to be really buggy
357 in this area!<br />
360 that your user/password pair are not in clear in the configuration file.
361 </li>
364 authentication modes are more secure: the MySQL login information does
365 not need to be set in the phpMyAdmin configuration file (except possibly
367 However, keep in mind that the password travels in plain text, unless
368 you are using the HTTPS protocol.<br />
369 In cookie mode, the password is stored, encrypted with the blowfish
370 algorithm, in a temporary cookie.</li>

411 the first GRANT SELECT query by this one:

428 Of course, the above queries only work if your MySQL version supports
432 on a set of particular databases. Normally you shouldn't give global
433 privileges to an ordinary user, unless you understand the impact of those
434 privileges (for example, you are creating a superuser).<br />

2074 <!-- TRANSFORMATIONS -->
2080 </ol>
2084 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2086 section</a> on how to do so.</p>
2088 <p> You can apply different transformations to the contents of each field. The
2089 transformation will take the content of each field and transform it with
2090 certain rules defined in the selected transformation.</p>
2092 <p> Say you have a field 'filename' which contains a filename. Normally you would
2093 see in phpMyAdmin only this filename. Using transformations you can transform
2094 that filename into a HTML link, so you can click inside of the phpMyAdmin
2095 structure on the field's link and will see the file displayed in a new browser
2096 window. Using transformation options you can also specify strings to
2097 append/prepend to a string or the format you want the output stored in.</p>
2099 <p> For a general overview of all available transformations and their options,
2100 you can consult your
2101 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2102 installation.</p>
2104 <p> For a tutorial on how to effectively use transformations, see our
2106 the official phpMyAdmin homepage.</p>
2110 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2111 clicking on the 'Structure' link for a table). There click on
2112 "Change" (or change icon) and there you will see three new fields at
2113 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2114 'Transformation options'.</p>
2116 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2117 that corresponds to the column's contents. Please note that
2118 transformations are inactive as long as no MIME-type is selected.</li>
2120 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2121 hopefully growing amount of pre-defined transformations. See below for information on
2122 how to build your own transformation.<br />
2124 There are global transformations and mimetype-bound transformations. Global transformations
2125 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2126 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2127 transformations which operate on the main mimetype (like 'image'), which will most likely
2128 take the subtype into regard, and those who only operate on a
2129 specific subtype (like 'image/jpeg').<br />
2131 You can use transformations on mimetypes for which the function was not defined for. There
2132 is no security check for you selected the right transformation, so take care of what the
2133 output will be like.</li>
2135 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2136 transform-function specific options here. Usually the transforms can operate with default
2137 options, but it is generally a good idea to look up the overview to see which options are
2138 necessary.<br />
2140 Much like the ENUM/SET-Fields, you have to split up several options using the format
2141 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2142 parsed as an array, leaving the first value the first element in the array, and so
2143 forth.<br />
2145 If you want to specify a MIME character set you can define it in the transformation_options.
2146 You have to put that outside of the pre-defined options of the specific mime-transform,
2148 for which you can specify 2 options and you want to append a character set, enter "'first
2149 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2151 </ul>
2155 <p> All mimetypes and their transformations are defined through single files in
2156 the directory 'libraries/transformations/'.</p>
2158 <p> They are stored in files to ease up customization and easy adding of new
2159 transformations.</p>
2161 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2162 always work. It makes no sense to apply a transformation to a mimetype, the
2163 transform-function doesn't know to handle.</p>
2165 <p> One can, however, use empty mime-types and global transformations which should work
2166 for many mimetypes. You can also use transforms on a different mimetype they where built
2167 for, but pay attention to option usage as well as what the transformation does to your
2168 field.</p>
2170 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2171 any other transform function and provides some basic functions.</p>
2173 <p> There are 5 possible file names:</p>
2175 <ol><li>A mimetype+subtype transform:<br /><br />
2177 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2179 Please not that mimetype and subtype are separated via '_', which shall
2180 not be contained in their names. The transform function/filename may
2181 contain only characters which cause no problems in the file system as
2182 well as the PHP function naming convention.<br /><br />
2184 The transform function will the be called
2185 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2187 <b>Example:</b><br /><br />
2189 <tt>text_html__formatted.inc.php</tt><br />
2190 <tt>PMA_transform_text_html__formatted()</tt></li>
2192 <li>A mimetype (w/o subtype) transform:<br /><br />
2194 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2196 Please note that there are no single '_' characters.
2197 The transform function/filename may contain only characters which cause
2198 no problems in the file system as well as the PHP function naming
2199 convention.<br /><br />
2201 The transform function will the be called
2202 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2204 <b>Example:</b><br /><br />
2206 <tt>text__formatted.inc.php</tt><br />
2207 <tt>PMA_transform_text__formatted()</tt></li>
2209 <li>A mimetype+subtype without specific transform function<br /><br />
2211 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2213 Please note that there are no '__' characters in the filename. Do not
2214 use special characters in the filename causing problems with the file
2215 system.<br /><br />
2217 No transformation function is defined in the file itself.<br /><br />
2219 <b>Example:</b><br /><br />
2221 <tt>text_plain.inc.php</tt><br />
2222 (No function)</li>
2224 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2226 <tt>[mimetype].inc.php</tt><br /><br />
2228 Please note that there are no '_' characters in the filename. Do not use
2229 special characters in the filename causing problems with the file system.
2230 <br /><br />
2232 No transformation function is defined in the file itself.<br /><br />
2234 <b>Example:</b><br /><br />
2236 <tt>text.inc.php</tt><br />
2237 (No function)</li>
2239 <li>A global transform function with no specific mimetype<br /><br />
2241 <tt>global__[transform].inc.php</tt><br /><br />
2243 The transform function will the be called
2244 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2246 <b>Example:</b><br /><br />
2248 <tt>global__formatted</tt><br />
2249 <tt>PMA_transform_global__formatted()</tt></li>
2250 </ol>
2252 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2253 transform function.</p>
2255 <p> All filenames containing no '__' in themselves are not shown as valid transform
2256 functions in the dropdown.</p>
2258 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2259 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2260 without a transform function. Also note the introduction of a function description in
2261 the language files. For each function a $strTransformation_[filename without .inc.php]
2262 has to exist.</p>
2264 <p> You can use the template generator to generate new functions and entries in the
2265 language file.</p>
2267 <p> To create a new transform function please see
2268 <tt>libraries/transformations/template_generator.sh</tt>.
2269 To create a new, empty mimetype please see
2270 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2272 <p> A transform function always gets passed three variables:</p>
2274 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2275 you want to transform.</li>
2276 <li><b>$options</b> - Contains any user-passed options to a transform function
2277 as an array.</li>
2278 <li><b>$meta</b> - Contains an object with field information to your column.
2279 The data is drawn from the output of the
2281 function. This means, all object properties described on the
2283 available in this variable and can be used to transform a field accordingly
2284 to unsigned/zerofill/not_null/... properties.<br />
2285 The $meta->mimetype variable contains the original MIME-type of the
2286 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>

2397 We recommend the following setup for Apache servers running in safe mode,
2398 to enable uploads of files while being reasonably secure:</p>
2400 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2401 <li>give ownership to the Apache server's user.group:

2443 <p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir

2447 owner as the owner of your phpMyAdmin directory. The uploaded files will

2485 </h4>
2487 <p> Starting with version 2.7.0, the import engine has been re–written and these
2488 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2489 to take advantage of the new import features.</p>
2491 <p> The first things to check (or ask your host provider to check) are the
2492 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2493 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2494 All of these three settings limit the maximum size of data that can be
2495 submitted and handled by PHP. One user also said that post_max_size
2496 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2498 There exist several workarounds if your upload is too big or your
2499 hosting provider is unwilling to change the settings:</p>

2509 or any third party applications, but are aware of users having success
2510 with it.</li>
2511 <li>If you have shell (command line) access, use MySQL to import the files
2512 directly. You can do this by issuing the "source" command from
2513 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2514 </ul>

2520 <p> All MySQL versions from 3.23.32 till 5.0 (except for 4.1.0 and 4.1.1) are
2521 fully supported. Please note that the older your MySQL version is, the more
2522 limitations you will have to face.<br />

2527 Either way, the developers of both extensions recommend to use the classic
2528 extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and newer.<br />
2529 When compiling php, we strongly recommend that you manually link the MySQL
2530 extension of your choice to a MySQL client library of at least the same
2531 minor version since the one that is bundled with some php distributions is

2586 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2587 "MySQL extension". This extension may be part of the PHP
2588 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2589 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2590 to load the extension but failed.<br /><br />
2592 Usually, the problem is solved by installing a software package called
2593 "PHP-MySQL" or something similar.</p>

2613 <p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
2614 defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
2615 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2616 Just edit your <tt>my.ini</tt> file that should be located in your Windows
2617 directory and add the following line to the group [mysqld]:</p>
2619 <pre>set-variable = lower_case_table_names=0</pre>
2621 <p> Next, save the file and restart the MySQL service. You can always check the

2672 message 'Errorcode: 13'. What does this mean?</a></h4>
2674 <p> This can happen due to a MySQL bug when having database / table names with
2675 upper case characters although <tt>lower_case_table_names</tt> is set to 1.
2676 To fix this, turn off this directive, convert all database and table names
2677 to lower case and turn it on again. Alternatively, there's a bug-fix
2678 available starting with MySQL 3.23.56 / 4.0.11-gamma.</p>
2682 and the fields are duplicated.</a></h4>
2684 <p> It is possible to configure Apache in such a way that PHP has problems
2685 interpreting .php files.</p>
2687 <p> The problems occur when two different (and conflicting) set of directives
2688 are used:</p>
2690 <pre>
2691 SetOutputFilter PHP
2692 SetInputFilter PHP

2695 <p> and</p>
2697 <pre>AddType application/x-httpd-php .php</pre>
2699 <p> In the case we saw, one set of directives was in
2700 <tt>/etc/httpd/conf/httpd.conf</tt>, while
2701 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2702 The recommended way is with <tt>AddType</tt>, so just comment out
2703 the first set of lines and restart Apache:</p>
2705 <pre>
2706 #SetOutputFilter PHP
2707 #SetInputFilter PHP
2708 </pre>
2713 <p> This problem is known to happen when the server is running Turck MMCache
2714 but upgrading MMCache to version 2.3.21 solves the problem.</p>
2719 <p> Yes.<br />
2720 However, phpMyAdmin needs to be backwards compatible to php4. This is why
2721 phpMyAdmin disables the <tt>E_STRICT</tt> error_level in
2722 <tt>error_reporting</tt> settings.

2796 <p> If your cluster consist of different architectures, PHP code used for

2834 into PHP.</p>
2838 connect to local MySQL server through socket '/tmp/mysql.sock'
2839 (111) ..." is displayed. What can I do?</a></h4>
2841 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
2843 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
2844 In your <i>php.ini</i> you will find a line</p>
2846 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
2848 <p> change it to</p>
2850 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
2852 <p> Then restart apache and it will work.</p>
2854 <p> Here is a fix suggested by Brad Ummer:</p>
2856 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
2857 To do this, telnet to your server and go to the MySQL bin directory. In
2858 this directory there should be a file named <i>mysqladmin</i>. Type
2859 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
2860 info about your MySQL server, including the socket
2861 (<i>/tmp/mysql.sock</i>, for example).</li>
2862 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
2863 phpMyAdmin, you need to complete the socket information in the
2864 <i>config.inc.php</i>.<br />
2865 For example:
2867 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
2868 <br /><br />
2870 Please also make sure that the permissions of this file allow to be readable
2871 by your webserver (i.e. '0755').</li>
2872 </ul>
2874 <p> Have also a look at the
2876 corresponding section of the MySQL documentation</a>.</p>
2880 what can I do?</a></h4>
2883 directive to <tt>FALSE</tt> in the phpMyAdmin configuration file. It helps
2884 sometime.<br />
2885 Also have a look at your PHP version number: if it contains "4.0b..."
2886 it means you're running a beta version of PHP. That's not a so good idea,
2887 please upgrade to a plain revision.</p>
2891 or a table, an error 404 (page not found) is displayed or, with <abbr title="HyperText Transfer Protocol">HTTP</abbr> or

2894 <p> Check the value you set for the
2896 directive in the phpMyAdmin configuration file.</p>
2900 password: YES)"-error when trying to access a MySQL-Server on a
2901 host which is port-forwarded for my localhost.</a></h4>
2903 <p> When you are using a port on your localhost, which you redirect via
2904 port-forwarding to another host, MySQL is not resolving the localhost
2905 as expected.<br />
2906 Erik Wasser explains: The solution is: if your host is "localhost"
2907 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
2908 connection for speeding up things. And that doesn't work in this configuration
2909 with port forwarding.<br />
2915 <p> Themes are configured with
2919 <br />
2921 should not delete the directory "original" or its underlying
2922 structure, because this is the system theme used by phpMyAdmin.
2923 "original" contains all images and styles, for backwards
2924 compatibility and for all themes that would not include images or css-files.
2925 <br /><br />
2928 is enabled, you can select your favorite theme on the main page. Your
2929 selected theme will be stored in a cookie.<br /><br /></p>
2931 <p> To create a theme:</p>
2933 <ul><li>make a new subdirectory (for example "your_theme_name") under
2935 (by default <tt>themes</tt>)</li>
2936 <li>copy the files and directories from "original" to
2937 "your_theme_name"</li>
2938 <li>edit the css-files in "your_theme_name/css"</li>
2939 <li>put your new images in "your_theme_name/img"</li>
2940 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
2941 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
2942 contain your chosen theme name, that will be visible in user interface</li>
2943 <li>make a new screenshot of your theme and save it under
2944 "your_theme_name/screen.png"</li>
2945 </ul>
2947 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
2948 theme verbose name, theme generation and theme version. These versions and
2949 generations are enumerated from 1 and do not have any direct dependence on
2950 phpMyAdmin version. Themes within same generation should be backwards
2951 compatible - theme with version 2 should work in phpMyAdmin requiring
2952 version 1. Themes with different generation are incompatible.</p>
2954 <p> If you do not want to use your own symbols and buttons, remove the
2955 directory "img" in "your_theme_name". phpMyAdmin will
2956 use the default icons and buttons (from the system-theme "original").
2957 </p>
2961 what can I do?</a></h4>
2963 <p> Here are a few points to check:</p>
2965 <ul><li>In <tt>config.inc.php</tt>, try to leave the
2967 directive empty. See also
2969 </li>
2970 <li>Maybe you have a broken PHP installation or you need to upgrade
2971 your Zend Optimizer. See
2973 http://bugs.php.net/bug.php?id=31134</a>.
2974 </li>
2975 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
2976 set to the default (200) or another low value, you could get this
2977 error if your table has a high number of columns. Adjust this setting
2978 accordingly. (Thanks to Klaus Dorninger for the hint).
2979 </li>
2980 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
2981 of ";" will cause this error. Replace it with "&;".
2982 </li>
2984 you might want to increase
2986 </li>
2987 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
2988 </li>
2989 </ul>
2996 who logged out can not log in again in with the same nick.</a></h4>
2998 <p> This is related to the authentication mechanism (protocol) used by
2999 phpMyAdmin. To bypass this problem: just close all the opened
3000 browser windows and then go back to phpMyAdmin. You should be able to
3001 log in again.</p>
3005 limit error or a time limit error.</a></h4>
3007 <p> Compressed dumps are built in memory and because of this are limited to
3008 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3009 using
3011 (enabled by default). Zip exports can not be handled this way, so if you need
3012 Zip files for larger dump, you have to use another way.</p>
3016 or alter a table.</a></h4>
3018 <p> This seems to be a InnoDB bug (fixed in MySQL 3.23.50?).</p>
3022 bundled with the MySQL server distribution.</a></h4>
3024 <p> The problem is that older versions of mysqldump created invalid comments like this:</p>
3026 <pre>
3027 -- MySQL dump 8.22
3028 --
3029 -- Host: localhost Database: database
3030 ---------------------------------------------------------
3031 -- Server version 3.23.54
3032 </pre>
3034 <p> The invalid part of the code is the horizontal line made of dashes that
3035 appears once in every dump created with mysqldump. If you want to run your
3036 dump you have to turn it into valid MySQL. This means, you have to add a
3037 whitespace after the first two dashes of the line or add a # before it:
3038 <br />
3039 <code>
3040 -- -------------------------------------------------------<br />
3041 </code>
3042 or<br />
3043 <code>
3044 #---------------------------------------------------------
3045 </code>
3046 </p>
3053 <p> Please note that you should not use the separating string multiple times
3054 without any characters between them, or at the beginning/end of your table
3055 name. If you have to, think about using another TableSeparator or disabling
3056 that feature</p>

3064 LEFT JOIN from the foreign table.<br /><br/>
3065 </p>
3069 I get series of errors like "Warning: unable to parse url". How
3070 can this be fixed?</a></h4>
3071 <p>
3072 Your table neither have a primary key nor an unique one, so we must use a
3073 long expression to identify this row. This causes problems to parse_url
3074 function. The workaround is to create a primary or unique key.
3075 <br />
3076 </p>
3080 a MIME-Transformation onto!</a></h4>
3082 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3083 nested forms can be put inside the table where phpMyAdmin displays the results.
3084 You can, however, use any form inside of a table if keep the parent
3085 form-container with the target to tbl_row_delete.php and just put your own
3086 input-elements inside. If you use a custom submit input field, the form will
3087 submit itself to the displaying page again, where you can validate the
3088 $HTTP_POST_VARS in a transformation.
3090 For a tutorial on how to effectively use transformations, see our
3092 on the official phpMyAdmin-homepage.</p>
3096 MySQL server</a></h4>
3098 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3101 http://dev.mysql.com/doc/mysql/en/ANSI_mode.html</a>). Most important of all,
3102 the quote-character (") is interpreted as an identifier quote character and
3103 not as a string quote character, which makes many internal phpMyAdmin
3105 statements. There is no workaround to this behaviour. News to this item will
3106 be posted in Bug report

3116 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3117 can use it for the Edit and Delete links.</p>
3122 <p> phpMyAdmin uses a quick method to get the row count, and this method
3123 only returns an approximate count in the case of InnoDB tables. See
3125 a way to modify those results, but
3126 this could have a serious impact on performance.</p>
3131 <p> The number of records in queries containing COUNT and GROUP BY is
3132 not correctly calculated. Also, sorting results of a query like
3137 containing an hyphen.
3138 </a></h4>
3139 <p>
3140 The tests I have made with current MySQL 4.1.11 API shows that the
3141 API does not accept this syntax for the USE command. Enclosing the
3142 db name with backquotes works. For further confusion, no backquotes
3143 are needed with command-line mysql.

3273 <p>When starting phpMyAdmin, you can use the <tt>db</tt>, <tt>pma_username</tt>, <tt>pma_password</tt> and <tt>server</tt> parameters. This last one can contain either the numeric host index (from <tt>$i</tt> of the configuration file) or one of the host names present in the configuration file. Using <tt>pma_username</tt> and <tt>pma_password</tt> has been tested along with the usage of 'cookie' <tt>auth_type</tt>.</p>
3279 when trying to create a table with more than 14 fields.

3281 <p>
3282 We could reproduce this problem only under Win98/98SE. Testing under
3283 WinNT4 or Win2K, we could easily create more than 60 fields.
3284 <br />
3285 A workaround is to create a smaller number of fields, then come back to
3286 your table properties and add the other fields.

3520 <p> Here is an example with the tables persons, towns and countries, all
3522 table, create it as explained in the configuration section. Then create the
3523 example tables:</p>
3525 <pre>
3526 CREATE TABLE REL_countries (
3527 country_code char(1) NOT NULL default '',
3528 description varchar(10) NOT NULL default '',
3529 PRIMARY KEY (country_code)
3530 ) TYPE=MyISAM;
3532 INSERT INTO REL_countries VALUES ('C', 'Canada');
3534 CREATE TABLE REL_persons (

3540 ) TYPE=MyISAM;
3542 INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
3543 INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
3545 CREATE TABLE REL_towns (
3547 description varchar(30) NOT NULL default '',
3548 PRIMARY KEY (town_code)
3549 ) TYPE=MyISAM;
3551 INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
3552 INSERT INTO REL_towns VALUES ('M', 'Montréal');
3553 </pre>
3559 <li>in Links, for "country_code" choose "REL_countries->country_code"</li>

3571 <li>In the fields row, choose persons.person_name and click the
3573 <li>Do the same for towns.description and countries.descriptions in the
3576 the correct joins have been generated</li>
3578 </ul>
3582 <p>
3583 Starting from the previous example, create the pma_table_info as explained
3584 in the configuration section, then browse your persons table,
3585 and move the mouse over a town code or country code.
3586 <br /><br />
3587 See also <a href="#faq6_21"><abbr title="Frequently Asked Questions">FAQ</abbr> 6.21</a> for an additional feature that "display field"
3588 enables: drop-down list of possible values.
3589 </p>
3592 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3593 <p>
3596 <br /><br />
3597 Then you need to think about your schema layout. Which tables will go on
3598 which pages?
3599 </p>
3600 <ul>
3606 page and click Go. If you like, you
3608 linked tables onto the new page.</li>
3609 <li>Select the name of the new page (making sure the Edit radio button
3610 is selected) and click Go.</li>
3612 Coordinates are relative; your diagram will
3613 be automatically scaled to fit the page. When initially placing tables
3614 on the page, just pick any coordinates -- say, 50x50. After clicking
3616 position the element correctly.</li>
3618 first be sure to click the Save
3619 button beneath the list of tables and coordinates, to save any changes
3620 you made there. Then scroll all the way down, select the
3622 you want, and click Go.</li>
3623 <li>Internet Explorer for Windows may suggest an incorrect filename when
3628 browsers on Windows, do not have this problem.</li>
3629 </ul>
3633 columns!</a></h4>
3635 <p> No, it's MySQL that is doing
3641 underscores in the database name?</a></h4>
3643 <p> If you do not put a backslash before the underscore, this is a wildcard
3646 john2db ...<br /><br />
3648 If you put a backslash before the underscore, it means that the database
3649 name will have a real underscore.</p>
3653 statistics pages?</a></h4>
3664 if it already exists during the import. It does NOT drop the table after
3665 your export, it only affects the import file.</li>
3667 Otherwise, you may get an error if the table name exists but has a
3668 different structure.</li>
3670 (if any) will be included in backup.</li>
3672 field and table names formed with special characters are protected.</li>
3674 types set in the pmadb in the dump as
3676 </li>
3677 </ul>
3682 command, for better documentation (but resulting file is bigger).</li>
3684 once the INSERT verb and the table name.</li>
3687 </li>
3689 more info is provided in the
3691 but basically with this selected, invalid values are adjusted and
3692 inserted rather than causing the entire statement to fail.</li>
3693 </ul>
3697 in its name.</a></h4>
3700 is the normal way to reference a database and table name. Worse, MySQL
3701 will usually let you create a database with a dot, but then you cannot
3702 work with it, nor delete it.</p>
3715 for usage.<br />
3716 On a more recent pear version, I had problems with the state of Net_DIME
3717 being beta, so this single command
3719 needed modules.<br />
3720 If you use the Validator, you should be aware that any
3722 submit will be stored anonymously (database/table/column names,
3723 strings, numbers replaced with generic values). The Mimer
3726 We utilize it as free SOAP service.</p>
3730 it, but MySQL says "BLOB column '...' used in key specification without
3733 <p> The right way to do this, is to create the field without any indexes,
3735 dialog. On this page, you will be able to choose your BLOB field, and
3736 set a size to the index, which is the condition to create an index on
3737 a BLOB field.</p>
3741 editing fields?</a></h4>
3743 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
3744 with many editing fields (table structure changes, row editing, etc.)
3745 (must be enabled in configuration - see.
3747 You can also have a look at the directive
3749 ('vertical') and see if this eases up editing for you.</p>
3753 WTF is this feature then useful for?</a></h4>
3755 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3756 on them. Otherwise you could just put a comment on the field. Because entering
3757 your own mimetype will cause serious syntax checking issues and validation,
3758 this introduces a high-risk false-user-input situation. Instead you have to
3759 initialize mimetypes using functions or empty mimetype definitions.<br />
3760 Plus, you have a whole overview of available mimetypes. Who knows all those
3761 mimetypes by heart so he/she can enter it at will?</p>
3765 can't I see any bookmarks below the query box? What is this variable for?
3766 </a></h4>
3768 <p> Any query you have executed can be stored as a bookmark on the page where the
3769 results are displayed. You will find a button labeled 'Bookmark this query'
3770 just at the end of the page.<br />
3771 As soon as you have stored a bookmark, it is related to the database you run
3772 the query on. You can now access a bookmark dropdown on each page, the query
3773 box appears on for that database.<br /><br />
3775 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
3779 aware of that you HAVE to create a valid query, otherwise your query won't be
3780 even able to be stored in the database.<br />
3782 for your query will remain the way it is, but will be stripped of the /**/
3783 chars. So you can use:<br /><br />
3787 which will be expanded to<br /><br />
3791 in your query, where VARIABLE is the string you entered in the input box. If
3792 an empty string is provided, no replacements are made.<br /><br />
3794 A more complex example. Say you have stored this query:<br /><br />
3796 <br /><br />
3799 the full query will be:<br /><br />
3802 <br /><br />
3806 spaces inserted there
3807 will be later also inserted as spaces in your query and may lead to unexpected
3808 results especially when
3810 Your initial query which is going to be stored as a bookmark has to yield at
3811 least one result row so
3812 you can store the bookmark. You may have that to work around using well
3816 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
3817 include exported table?</a></h4>
3819 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
3820 document should look like following one (assuming you have table
3823 <pre>
3824 \documentclass{article} % or any class you want
3825 \usepackage{longtable} % for displaying table
3826 \begin{document} % start of document
3827 \include{table} % including exported table
3828 \end{document} % end of document
3829 </pre>
3833 access them.
3834 </a></h4>
3837 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
3838 enable users to see all the database names.
3841 So if your users do not need those privileges, you can remove them and their
3842 databases list will shorten.</p>
3846 possible values for a field, based on some foreign table?</a></h4>
3848 <p> You have to setup appropriate links between the tables, and also
3852 foreign table, a drop-down list of values will be available.
3853 You will see two lists of values, the first list containing the key
3854 and the display field, the second list containing the display field
3855 and the key. The reason for this is to be able to type the first
3856 letter of either the key or the display field.<br /><br />
3858 For 200 values or more, a distinct window will appear, to browse foreign
3859 key values and choose one.</p>
3863 automatically when entering Browse mode for a table?</a></h4>
3865 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
3866 </p>
3870 Excel files, how can I enable that?</a></h4>
3872 <p> Current version does support direct export to Microsoft Excel and Word
3873 versions 2000 and newer. If you need export older versions, you can use
3875 which works out of the box or you can
3877 several problems, most important are limitation of cell content to 255
3878 chars and no support for charsets, so think carefully whether you want to
3879 enable this.</b>. For enabling this you need to set
3883 module Spreadsheet_Excel_Writer into php include path. The
3884 installation can be done by following command:</p>
3886 <pre>
3887 pear -d preferred_state=beta install -a Spreadsheet_Excel_Writer
3888 </pre>
3890 <p> First part of switches set we want to install beta version of that module
3891 (no stable version available yet) and then we tell pear we want to satisfy
3892 dependencies.</p>
3894 <p> If you are running in PHP safe mode, you will have to set
3897 modules are located, for example:</p>
3899 <pre>
3900 safe_mode_include_dir = /usr/local/lib/php
3901 </pre>
3905 <pre>
3906 cd phpMyAdmin
3907 mkdir tmp
3908 chmod o+rwx tmp
3909 </pre>
3913 what happens to my column comments stored in pmadb?</a></h4>
3915 <p> Automatic migration of a table's pmadb-style column comments to the native
3916 ones is done whenever you enter Structure page for this table.</p>
3923 <p> Our Bug Tracker is located at
3925 under the Bugs section.<br /><br />
3927 But please first discuss your bug with other users:<br />

3939 Please note that we try not to use HTML entities like &eacute; in
3940 the translations, since we define the right character set in the file.
3941 With HTML entities, the text on JavaScript messages would not
3942 display correctly.
3943 However there are some entities that need to be there, for quotes
3944 ,non-breakable spaces, ampersands, less than, greater than.<br />
3945 You can then put your translations, as a zip file to avoid losing special
3946 characters, on the sourceforge.net translation tracker.<br />

4189 ---------------------------------
4191 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4192 to create a web-based interface to MySQL using PHP3. Although I have not
4193 used any of his source-code, there are some concepts I've borrowed from
4194 him. phpMyAdmin was created because Peter told me he wasn't going to
4195 further develop his (great) tool.
4196 Thanks go to
4198 code for the check when dropping a table or database. He also suggested
4199 that you should be able to specify the primary key on tbl_create.php3. To
4200 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4201 well as a bug-report. Plus many smaller improvements.
4203 were introduced in 1.3.0 (including quite significant ones like the
4204 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4205 bug-fixes and help.
4207 language-independent by outsourcing the strings to a separate file. He
4208 also contributed the French translation.
4210 tbl_select.php3, a feature to display only some fields from a table.
4212 functions in tbl_change.php3. He also added the
4215 servers and is a regular contributor for bug-fixes.
4217 features for 2.0.6.
4218 The following people have contributed minor changes, enhancements, bugfixes
4219 or support for a new language:
4220 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4221 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4222 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4223 G. Wieggers.
