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

146 </ul>
149 <p> Many people have difficulty
150 understanding the concept of user management with regards to phpMyAdmin. When
151 a user logs in to phpMyAdmin, that username and password are passed directly
152 to MySQL. phpMyAdmin does no account management on its own (other than
153 allowing one to manipulate the MySQL user account information); all users
154 must be valid MySQL users.</p>
163 <!-- INSTALLATION -->
171 </ol>
174 phpMyAdmin does not apply any special security methods to the MySQL database
175 server. It is still the system administrator's job to grant permissions on
177 be used for this.
178 </p>
186 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
187 before uploading them to your server, as PHP seems not to like
192 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
193 Downloads page. Some kits contain only the English messages,
194 others contain all languages in UTF-8 format (this should be fine
195 in most situations), others contain all
196 languages and all character sets. We'll assume you chose a kit whose
198 </li>
199 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
201 document root. If you don't have direct access to your document root,
202 put the files in a directory on your local machine, and, after step 4,
203 transfer the directory on your web server using, for example, ftp.</li>
204 <li>Ensure that all the scripts have the appropriate owner (if PHP is
205 running in safe mode, having some scripts with an owner different
206 from the owner of other scripts will be a
211 <li>Now you must configure your installation. There are two methods that
212 can be used. Traditionally, users have hand-edited a copy of
214 provided for those who prefer a graphical installation. Creating a
215 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
216 <ul><li>To manually create the file, simply use your text editor to
219 file) in the main (top-level) phpMyAdmin directory (the one
223 default value is okay for a particular setting, there is no
225 few directives to get going, a simple configuration may look
226 like this:
227 <pre>
228 <?php
229 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
231 $i=0;
232 $i++;
233 $cfg['Servers'][$i]['auth_type'] = 'cookie';
234 ?>
235 </pre>
236 Or, if you prefer to not be prompted every time you log in:
237 <pre>
238 <?php
240 $i=0;
241 $i++;
242 $cfg['Servers'][$i]['user'] = 'root';
243 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
244 $cfg['Servers'][$i]['auth_type'] = 'config';
245 ?>
246 </pre>
247 For a full explanation of possible configuration values, see the
253 directory. This is a security measure. On a Linux/Unix system you
254 can use the following commands:
255 <pre>
256 cd phpMyAdmin
257 mkdir config # create directory for saving
258 chmod o+rw config # give it world writable permissions
259 </pre>
260 And to edit an existing configuration, copy it over first:
261 <pre>
262 cp config.inc.php config/ # copy current configuration for editing
263 chmod o+w config/config.inc.php # give it world writable permissions
264 </pre>
265 On other platforms, simply create the folder and ensure that your
274 the webserver does not have the proper permissions you may see the
276 config/</tt> directory exists and has the proper permissions -
278 and upload (via FTP or some similar means) to the proper location.<br /><br />
280 Once the file has been saved, it must be moved out of the <tt>
281 config/</tt> directory and the permissions must be reset, again
282 as a security measure:
283 <pre>
284 mv config/config.inc.php . # move file to current directory
285 chmod o-rw config.inc.php # remove world read and write permissions
286 rm -rf config # remove not needed directory
287 </pre>
288 Now the file is ready to be used. You can choose to review or edit
289 the file with your favorite editor, if you prefer to set some
290 advanced options which the setup script does not provide.</li></ul></li>
291 <li>If you are using the
293 protect the phpMyAdmin installation directory because using
294 config does not require a user to
295 enter a password to access the phpMyAdmin installation. Use of an alternate
296 authentication method is recommended, for example with
304 in your browser. phpMyAdmin should now display a welcome screen
305 and your databases, or a login dialog if using
307 authentication mode.</li>
310 Apache you can use supplied .htaccess file in that folder, for other
311 webservers, you should configure this yourself. Such configuration
312 prevents from possible path exposure and cross side scripting
313 vulnerabilities that might happen to be found in that code.</li>
314 <li>
315 It is generally good idea to protect public phpMyAdmin installation
316 against access by robots as they usually can not do anything good

326 <p> For a whole set of new features (bookmarks, comments,
328 tracking mechanism,
330 transformation, etc.) you need to create a set of special tables. Those
331 tables can be located in your own database, or in a central database for a
332 multi-user installation (this database would then be accessed by the
333 controluser, so no other user should have rights to it).</p>
344 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
345 that you may need special (administrator) privileges to create the database
346 and tables, and that the script may need some tuning, depending on the
347 database name.</p>

359 unpacked one. Configuration files from old versions may
360 require some tweaking as some options have been changed or removed; in

368 is version-specific.</p>
371 version 5.x or newer and if you use the phpMyAdmin configuration storage,
372 you should run the SQL script found in
379 where you want to give users access to their own database and don't want
380 them to play around with others.<br />
381 Nevertheless be aware that MS Internet Explorer seems to be really buggy
385 that your user/password pair are not in clear in the configuration file.
386 </li>
389 authentication modes are more secure: the MySQL login information does
390 not need to be set in the phpMyAdmin configuration file (except possibly
392 However, keep in mind that the password travels in plain text, unless
393 you are using the HTTPS protocol.<br />

544 web applications.<br /><br />
545 When Swekey authentication is activated, phpMyAdmin requires the
546 users's Swekey to be plugged before entering the login page (currently
547 supported for cookie authentication mode only). Swekey Authentication is

947 Since release 2.3.0 you can describe, in a special 'table_info'
948 table, which column is to be displayed as a tool-tip when moving the
949 cursor over the corresponding key.<br />
950 This configuration variable will hold the name of this special
951 table. To allow the usage of this functionality:
953 <li>put the table name in
955 'pma_table_info')</li>

998 column name (properties page) or embedded within the header of table in
999 browse view. They can also be shown in a table dump. Please see the
1000 relevant configuration directives later on.<br /><br />
1002 Also new in release 2.5.0 is a MIME-transformation system which is also
1004 Transformations</a> for further information. To use the
1005 MIME-transformation system, your column_info table has to have the three
1006 new columns 'mimetype', 'transformation', 'transformation_options'.

1036 don't want to use a table-based history, you can use the JavaScript-based
1037 history. Using that, all your history items are deleted when closing the
1038 window.<br /><br />
1040 Using
1042 you can specify an amount of history items you want to have on hold. On
1043 every login, this list gets cut to the maximum amount.<br /><br />

1061 Since release 3.3.x a tracking mechanism is available.
1063 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1064 and data definition statements. After enabling it you can create versions of tables.
1065 <br/><br/>
1066 The creation of a version has two effects:
1068 <ul>
1070 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1071 </ul>
1073 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1074 For the report you can use filters, for example you can get a list of statements within a date range.
1075 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1076 In addition you can export the (filtered) report to a file or to a temporary database.

1902 row on a horizontal line, the second rotates the headers by 90

1910 The HeaderFlipType can be set to 'auto', 'css' or 'fake'. When using
1911 'css' the rotation of the header for horizontalflipped is done via
1912 CSS. The CSS transformation currently works only in Internet
1913 Explorer.If set to 'fake' PHP does the transformation for you, but of
1914 course this does not look as good as CSS. The 'auto' option enables
1915 CSS transformation when browser supports it and use PHP based one

2085 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2086 or icon is always displayed on the left panel. If JavaScript is enabled in
2087 your browser, a click on this opens a distinct query window, which is
2088 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2089 changes to display a query box.<br /><br />

2103 The usage of the JavaScript query window is recommended if you have a

2115 When using the JavaScript based query window, it will always get
2116 updated when you click on a new table/db to browse and will focus if
2117 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2118 the query window by checking the box "Do not overwrite this query from
2119 outside the window" below the query textarea. Then you can browse
2120 tables/databases in the background without losing the contents of the

2334 <!-- TRANSFORMATIONS -->
2340 </ol>
2344 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2346 section</a> on how to do so.</p>
2348 <p> You can apply different transformations to the contents of each column. The
2349 transformation will take the content of each column and transform it with
2350 certain rules defined in the selected transformation.</p>
2352 <p> Say you have a column 'filename' which contains a filename. Normally you would
2353 see in phpMyAdmin only this filename. Using transformations you can transform
2354 that filename into a HTML link, so you can click inside of the phpMyAdmin
2355 structure on the column's link and will see the file displayed in a new browser
2356 window. Using transformation options you can also specify strings to
2357 append/prepend to a string or the format you want the output stored in.</p>
2359 <p> For a general overview of all available transformations and their options,
2360 you can consult your
2361 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2362 installation.</p>
2364 <p> For a tutorial on how to effectively use transformations, see our
2366 the official phpMyAdmin homepage.</p>
2370 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2371 clicking on the 'Structure' link for a table). There click on
2372 "Change" (or change icon) and there you will see three new
2373 fields at
2374 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2375 'Transformation options'.</p>
2377 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2378 that corresponds to the column's contents. Please note that
2379 transformations are inactive as long as no MIME-type is selected.</li>
2381 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2382 hopefully growing amount of pre-defined transformations. See below for information on
2383 how to build your own transformation.<br />
2385 There are global transformations and mimetype-bound transformations. Global transformations
2386 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2387 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2388 transformations which operate on the main mimetype (like 'image'), which will most likely
2389 take the subtype into regard, and those who only operate on a
2390 specific subtype (like 'image/jpeg').<br />
2392 You can use transformations on mimetypes for which the function was not defined for. There
2393 is no security check for you selected the right transformation, so take care of what the
2394 output will be like.</li>
2396 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2397 transform-function specific options here. Usually the transforms can operate with default
2398 options, but it is generally a good idea to look up the overview to see which options are
2399 necessary.<br />
2401 Much like the ENUM/SET-Fields, you have to split up several options using the format
2402 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2403 parsed as an array, leaving the first value the first element in the array, and so
2404 forth.<br />
2406 If you want to specify a MIME character set you can define it in the transformation_options.
2407 You have to put that outside of the pre-defined options of the specific mime-transform,
2409 for which you can specify 2 options and you want to append a character set, enter "'first
2410 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2412 </ul>
2416 <p> All mimetypes and their transformations are defined through single files in
2417 the directory 'libraries/transformations/'.</p>
2419 <p> They are stored in files to ease up customization and easy adding of new
2420 transformations.</p>
2422 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2423 always work. It makes no sense to apply a transformation to a mimetype the
2424 transform-function doesn't know to handle.</p>
2426 <p> One can, however, use empty mime-types and global transformations which should work
2427 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2428 for, but pay attention to option usage as well as what the transformation does to your
2429 column.</p>
2431 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2432 any other transform function and provides some basic functions.</p>
2434 <p> There are 5 possible file names:</p>
2436 <ol><li>A mimetype+subtype transform:<br /><br />
2438 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2440 Please not that mimetype and subtype are separated via '_', which shall
2441 not be contained in their names. The transform function/filename may
2442 contain only characters which cause no problems in the file system as
2443 well as the PHP function naming convention.<br /><br />
2445 The transform function will the be called
2446 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2448 <b>Example:</b><br /><br />
2450 <tt>text_html__formatted.inc.php</tt><br />
2451 <tt>PMA_transform_text_html__formatted()</tt></li>
2453 <li>A mimetype (w/o subtype) transform:<br /><br />
2455 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2457 Please note that there are no single '_' characters.
2458 The transform function/filename may contain only characters which cause
2459 no problems in the file system as well as the PHP function naming
2460 convention.<br /><br />
2462 The transform function will the be called
2463 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2465 <b>Example:</b><br /><br />
2467 <tt>text__formatted.inc.php</tt><br />
2468 <tt>PMA_transform_text__formatted()</tt></li>
2470 <li>A mimetype+subtype without specific transform function<br /><br />
2472 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2474 Please note that there are no '__' characters in the filename. Do not
2475 use special characters in the filename causing problems with the file
2476 system.<br /><br />
2478 No transformation function is defined in the file itself.<br /><br />
2480 <b>Example:</b><br /><br />
2482 <tt>text_plain.inc.php</tt><br />
2483 (No function)</li>
2485 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2487 <tt>[mimetype].inc.php</tt><br /><br />
2489 Please note that there are no '_' characters in the filename. Do not use
2490 special characters in the filename causing problems with the file system.
2491 <br /><br />
2493 No transformation function is defined in the file itself.<br /><br />
2495 <b>Example:</b><br /><br />
2497 <tt>text.inc.php</tt><br />
2498 (No function)</li>
2500 <li>A global transform function with no specific mimetype<br /><br />
2502 <tt>global__[transform].inc.php</tt><br /><br />
2504 The transform function will the be called
2505 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2507 <b>Example:</b><br /><br />
2509 <tt>global__formatted</tt><br />
2510 <tt>PMA_transform_global__formatted()</tt></li>
2511 </ol>
2513 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2514 transform function.</p>
2516 <p> All filenames containing no '__' in themselves are not shown as valid transform
2517 functions in the dropdown.</p>
2519 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2520 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2521 without a transform function.</p>
2523 <p> To create a new transform function please see
2524 <tt>libraries/transformations/template_generator.sh</tt>.
2525 To create a new, empty mimetype please see
2526 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2528 <p> A transform function always gets passed three variables:</p>
2530 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2531 you want to transform.</li>
2532 <li><b>$options</b> - Contains any user-passed options to a transform function
2533 as an array.</li>
2534 <li><b>$meta</b> - Contains an object with information about your column.
2535 The data is drawn from the output of the
2537 function. This means, all object properties described on the
2539 available in this variable and can be used to transform a column accordingly
2540 to unsigned/zerofill/not_null/... properties.<br />
2541 The $meta->mimetype variable contains the original MIME-type of the
2542 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2543 </ol>
2545 <p> Additionally you should also provide additional function to provide
2546 information about the transformation to the user. This function should
2547 have same name as transformation function just with appended
2548 <code>_info</code> suffix. This function accepts no parameters and returns
2549 array with information about the transformation. Currently following keys
2550 can be used:
2551 </p>
2552 <dl>
2553 <dt><code>info</code></dt>
2554 <dd>Long description of the transformation.</dd>

2713 <p> Starting with version 2.7.0, the import engine has been re–written and these
2714 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2715 to take advantage of the new import features.</p>
2717 <p> The first things to check (or ask your host provider to check) are the
2718 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2719 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2720 All of these three settings limit the maximum size of data that can be
2721 submitted and handled by PHP. One user also said that post_max_size
2722 and memory_limit need to be larger than upload_max_filesize.<br /> <br />

2744 support?</a></h4>
2746 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2747 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can

2797 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2798 "MySQL extension". This extension may be part of the PHP
2799 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2800 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2801 to load the extension but failed.<br /><br />

2883 To fix this, turn off this directive, convert all database and table names

2891 <p> It is possible to configure Apache in such a way that PHP has problems

2908 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2909 The recommended way is with <tt>AddType</tt>, so just comment out

3004 <p> If your cluster consist of different architectures, PHP code used for

3012 <p> Yes but the default configuration values of Suhosin are known to cause
3013 problems with some operations, for example editing a table with many
3014 columns and no primary key or with textual primary key.
3015 </p>
3016 <p>
3017 Suhosin configuration might lead to malfunction in some cases and it can
3018 not be fully avoided as phpMyAdmin is kind of application which needs to
3019 transfer big amounts of columns in single HTTP request, what is something
3020 what Suhosin tries to prevent. Generally all
3021 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3022 <code>suhosin.get.*</code> directives can have negative effect on
3023 phpMyAdmin usability. You can always find in your error logs which limit
3024 did cause dropping of variable, so you can diagnose the problem and adjust
3025 matching configuration variable.
3026 </p>
3027 <p>
3028 The default values for most Suhosin configuration options will work in most

3057 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3059 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />

3066 </pre>
3068 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3069 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.

3115 connect to local MySQL server through socket '/tmp/mysql.sock'
3116 (111) ..." is displayed. What can I do?</a></h4>
3118 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3120 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3121 In your <i>php.ini</i> you will find a line</p>
3123 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3125 <p> change it to</p>
3127 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3129 <p> Then restart apache and it will work.</p>
3131 <p> Here is a fix suggested by Brad Ummer:</p>
3133 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3134 To do this, telnet to your server and go to the MySQL bin directory. In
3135 this directory there should be a file named <i>mysqladmin</i>. Type
3136 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3137 info about your MySQL server, including the socket
3138 (<i>/tmp/mysql.sock</i>, for example).</li>
3139 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3140 phpMyAdmin, you need to complete the socket information in the
3141 <i>config.inc.php</i>.<br />
3142 For example:
3144 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3145 <br /><br />
3147 Please also make sure that the permissions of this file allow to be readable
3148 by your webserver (i.e. '0755').</li>

3180 <p> When you are using a port on your localhost, which you redirect via
3181 port-forwarding to another host, MySQL is not resolving the localhost
3182 as expected.<br />
3183 Erik Wasser explains: The solution is: if your host is "localhost"
3184 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3185 connection for speeding up things. And that doesn't work in this configuration

3227 phpMyAdmin version. Themes within same generation should be backwards
3228 compatible - theme with version 2 should work in phpMyAdmin requiring
3229 version 1. Themes with different generation are incompatible.</p>
3231 <p> If you do not want to use your own symbols and buttons, remove the
3232 directory "img" in "your_theme_name". phpMyAdmin will
3233 use the default icons and buttons (from the system-theme "original").
3234 </p>
3238 what can I do?</a></h4>
3240 <p> Here are a few points to check:</p>
3242 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3244 directive empty. See also
3246 </li>
3247 <li>Maybe you have a broken PHP installation or you need to upgrade
3248 your Zend Optimizer. See
3250 http://bugs.php.net/bug.php?id=31134</a>.
3251 </li>
3252 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3253 set to the default (200) or another low value, you could get this
3254 error if your table has a high number of columns. Adjust this setting
3255 accordingly. (Thanks to Klaus Dorninger for the hint).
3256 </li>
3257 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3258 of ";" will cause this error. Replace it with "&;".
3259 </li>
3261 you might want to increase
3263 </li>
3264 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3265 </li>
3266 </ul>
3271 <p> To be able to see a progress bar during your uploads, your server must
3274 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3275 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3282 who logged out can not log in again in with the same nick.</a></h4>
3284 <p> This is related to the authentication mechanism (protocol) used by
3285 phpMyAdmin. To bypass this problem: just close all the opened
3286 browser windows and then go back to phpMyAdmin. You should be able to
3287 log in again.</p>
3291 limit error or a time limit error.</a></h4>
3293 <p> Compressed dumps are built in memory and because of this are limited to
3294 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3295 using
3297 (enabled by default). Zip exports can not be handled this way, so if you need
3298 Zip files for larger dump, you have to use another way.</p>
3302 when I rename a table or a column.</a></h4>
3304 <p> This is an InnoDB bug, see <a href="http://bugs.mysql.com/bug.php?id=21704">http://bugs.mysql.com/bug.php?id=21704</a>.</p>
3308 bundled with the MySQL server distribution.</a></h4>
3310 <p> The problem is that older versions of <code>mysqldump</code> created invalid comments like this:</p>
3312 <pre>
3313 -- MySQL dump 8.22
3314 --
3315 -- Host: localhost Database: database
3316 ---------------------------------------------------------
3317 -- Server version 3.23.54
3318 </pre>
3320 <p> The invalid part of the code is the horizontal line made of dashes that
3321 appears once in every dump created with mysqldump. If you want to run your
3322 dump you have to turn it into valid MySQL. This means, you have to add a
3323 whitespace after the first two dashes of the line or add a # before it:
3324 <br />
3325 <code>
3326 -- -------------------------------------------------------<br />
3327 </code>
3328 or<br />
3329 <code>
3330 #---------------------------------------------------------
3331 </code>
3332 </p>
3339 <p> Please note that you should not use the separating string multiple times
3340 without any characters between them, or at the beginning/end of your table
3341 name. If you have to, think about using another TableSeparator or disabling
3342 that feature</p>
3347 <p> In Relation view, being able to choose a table in another database,
3348 or having more than one index column in the foreign key.<br /><br/>
3349 In Query-by-example (Query), automatic generation of the query
3350 LEFT JOIN from the foreign table.<br /><br/>
3351 </p>
3355 I get series of errors like "Warning: unable to parse url". How
3356 can this be fixed?</a></h4>
3357 <p>
3358 Your table neither have a primary key nor an unique one, so we must use a
3359 long expression to identify this row. This causes problems to parse_url
3360 function. The workaround is to create a primary or unique key.
3361 <br />
3362 </p>
3366 a MIME-Transformation onto!</a></h4>
3368 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3369 nested forms can be put inside the table where phpMyAdmin displays the results.
3370 You can, however, use any form inside of a table if keep the parent
3371 form-container with the target to tbl_row_delete.php and just put your own
3372 input-elements inside. If you use a custom submit input field, the form will
3373 submit itself to the displaying page again, where you can validate the
3374 $HTTP_POST_VARS in a transformation.
3376 For a tutorial on how to effectively use transformations, see our
3378 on the official phpMyAdmin-homepage.</p>
3382 MySQL server</a></h4>
3384 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3387 http://dev.mysql.com/doc/mysql/en/ansi-mode.html</a>). Most important of all,
3388 the quote-character (") is interpreted as an identifier quote character and
3389 not as a string quote character, which makes many internal phpMyAdmin
3391 statements. There is no workaround to this behaviour. News to this item will
3392 be posted in Bug report
3393 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3399 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3400 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3402 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3403 can use it for the Edit and Delete links.</p>
3408 <p> phpMyAdmin uses a quick method to get the row count, and this method
3409 only returns an approximate count in the case of InnoDB tables. See
3411 a way to modify those results, but
3412 this could have a serious impact on performance.</p>

3428 <p>
3429 This has been a known limitation of phpMyAdmin since the beginning and
3430 it's not likely to be solved in the future.
3431 </p>
3433 <!-- Begin: Excel import limitations -->
3436 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3437 <p>
3438 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3439 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3440 <br /><br />
3441 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3445 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3446 <p>
3447 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3448 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3449 </p>
3452 <a href="#faq3_17">3.17 When I import an Excel spreadsheet, my custom cell types are not represented as they are in Excel.</a></h4>
3453 <p>
3454 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3455 consider using a built-in type. These are almost always guarenteed to import correctly.
3456 </p>
3458 <!-- End: Excel import limitations -->
3459 <!-- Begin: CSV import limitations -->
3462 <a href="#faq3_18">3.18 When I import a CSV file that contains multiple tables, they are lumped together into a single table.</a></h4>
3463 <p>
3464 There is no reliable way to differetiate tables in CSV format. For the time being, you will have to break apart CSV files containing multiple tables.
3465 </p>
3467 <!-- End: CSV import limitations -->
3468 <!-- Begin: Import type-detection limitations -->
3471 <a href="#faq3_19">3.19 When I import a file and have phpMyAdmin determine the appropriate data structure it only uses int, decimal, and varchar types.</a></h4>
3472 <p>
3473 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
3474 you will have to edit the structure to your liking post-import.
3475 <br /><br />
3476 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
3477 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.

3980 If you put a backslash before the underscore, it means that the database
3981 name will have a real underscore.</p>
3985 statistics pages?</a></h4>
3996 if it already exists during the import. It does NOT drop the table after
3997 your export, it only affects the import file.</li>
3999 Otherwise, you may get an error if the table name exists but has a
4000 different structure.</li>
4002 (if any) will be included in backup.</li>
4004 column and table names formed with special characters are protected.</li>
4006 types set in the pmadb in the dump as

4014 command, for better documentation (but resulting file is bigger).</li>
4016 once the INSERT verb and the table name.</li>
4019 </li>
4021 more info is provided in the
4023 but basically with this selected, invalid values are adjusted and
4024 inserted rather than causing the entire statement to fail.</li>
4025 </ul>
4029 in its name.</a></h4>
4032 is the normal way to reference a database and table name. Worse, MySQL
4033 will usually let you create a database with a dot, but then you cannot
4034 work with it, nor delete it.</p>
4040 <p>
4041 To use SQL Validator, you need PHP with
4047 module.
4048 </p>
4050 <p>
4056 usage.
4057 </p>
4059 <p>
4060 If you use the Validator, you should be aware that any
4062 submit will be stored anonymously (database/table/column names,
4063 strings, numbers replaced with generic values). The Mimer
4066 We utilize it as free SOAP service.
4067 </p>
4071 it, but MySQL says "BLOB column '...' used in key specification without
4074 <p> The right way to do this, is to create the column without any indexes,
4076 dialog. On this page, you will be able to choose your BLOB column, and
4077 set a size to the index, which is the condition to create an index on
4078 a BLOB column.</p>
4082 editing fields?</a></h4>
4084 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4085 with many editing fields (table structure changes, row editing, etc.).
4086 You can also have a look at the directive
4088 ('vertical') and see if this eases up editing for you.</p>
4092 WTF is this feature then useful for?</a></h4>
4094 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4095 on them. Otherwise you could just put a comment on the column. Because entering
4096 your own mimetype will cause serious syntax checking issues and validation,
4097 this introduces a high-risk false-user-input situation. Instead you have to
4098 initialize mimetypes using functions or empty mimetype definitions.<br />
4099 Plus, you have a whole overview of available mimetypes. Who knows all those
4100 mimetypes by heart so he/she can enter it at will?</p>
4104 can't I see any bookmarks below the query box? What is this variable for?
4105 </a></h4>
4107 <p> Any query you have executed can be stored as a bookmark on the page where the
4108 results are displayed. You will find a button labeled 'Bookmark this query'
4109 just at the end of the page.<br />
4110 As soon as you have stored a bookmark, it is related to the database you run
4111 the query on. You can now access a bookmark dropdown on each page, the query
4112 box appears on for that database.<br /><br />
4114 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4118 aware of that you HAVE to create a valid query, otherwise your query won't be
4119 even able to be stored in the database.<br />
4121 for your query will remain the way it is, but will be stripped of the /**/
4122 chars. So you can use:<br /><br />
4126 which will be expanded to<br /><br />
4130 in your query, where VARIABLE is the string you entered in the input box. If
4131 an empty string is provided, no replacements are made.<br /><br />
4133 A more complex example. Say you have stored this query:<br /><br />
4135 <br /><br />
4138 the full query will be:<br /><br />
4141 <br /><br />
4143 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4145 spaces inserted there
4146 will be later also inserted as spaces in your query and may lead to unexpected
4147 results especially when
4149 Your initial query which is going to be stored as a bookmark has to yield at
4150 least one result row so
4151 you can store the bookmark. You may have that to work around using well
4155 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4156 include exported table?</a></h4>
4158 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4159 document should look like following one (assuming you have table
4162 <pre>
4163 \documentclass{article} % or any class you want
4164 \usepackage{longtable} % for displaying table
4165 \begin{document} % start of document
4166 \include{table} % including exported table
4167 \end{document} % end of document
4168 </pre>
4172 access them.
4173 </a></h4>
4175 <p> You have one of these global privileges: CREATE
4176 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4177 enable users to see all the database names.
4180 So if your users do not need those privileges, you can remove them and their
4181 databases list will shorten.</p>
4185 possible values for a column, based on some foreign table?</a></h4>
4187 <p> You have to setup appropriate links between the tables, and also
4191 foreign table, a drop-down list of values will be available.
4192 You will see two lists of values, the first list containing the key
4193 and the display column, the second list containing the display column
4194 and the key. The reason for this is to be able to type the first
4195 letter of either the key or the display column.<br /><br />
4197 For 100 values or more, a distinct window will appear, to browse foreign
4198 key values and choose one. To change the default limit of 100, see
4199 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4203 automatically when entering Browse mode for a table?</a></h4>
4205 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4206 </p>
4210 Excel files, how can I enable that?</a></h4>
4212 <p> You can use
4214 which works out of the box, but phpMyAdmin supports direct export
4215 to Microsoft Excel version 97 and newer. For this to work, you need to set
4220 <pre>
4221 cd phpMyAdmin
4222 mkdir tmp
4223 chmod o+rwx tmp
4224 </pre>
4228 what happens to my column comments stored in pmadb?</a></h4>
4230 <p> Automatic migration of a table's pmadb-style column comments to the native
4231 ones is done whenever you enter Structure page for this table.</p>
4236 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4237 <ul>
4240 later)</li>
4243 </ul>
4247 <ol>
4248 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of "localhost".</li>
4249 <li>Ensure that your target table is under the <tt>PBXT</tt> storage engine and has a <tt>LONGBLOB</tt> column (which must be nullable if you want to remove the BLOB reference from it).</li>
4250 <li>When you insert or update a row in this table, put a checkmark on the "Upload to BLOB repository" optional choice; otherwise, the upload will be done directly in your LONGBLOB column instead of the repository.</li>
4251 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example "View image". A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time.</li>
4252 </ol>
4257 <p> 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.</p>
4263 <p>
4264 In all places where phpMyAdmin accepts format strings, you can use
4267 expanded variables depend on a context (for example, if you haven't chosen a
4268 table, you can not get the table name), but the following variables can be used:
4269 </p>
4270 <dl>
4276 <dd>Verbose MySQL server name as defined in <a href="#cfg_Servers_verbose">server configuration</a></dd>
4287 </dl>
4292 <p>
4293 By clicking on the button 'toggle scratchboard' on the page
4294 where you edit x/y coordinates of those elements you can activate a
4295 scratchboard where all your elements are placed. By clicking on an
4296 element, you can move them around in the pre-defined area and the x/y
4297 coordinates will get updated dynamically. Likewise, when entering a
4298 new position directly into the input field, the new position in the
4299 scratchboard changes after your cursor leaves the input field.
4300 </p>
4301 <p>
4302 You have to click on the 'OK'-button below the tables to save the new
4303 positions. If you want to place a new element, first add it to the
4304 table of elements and then you can drag the new element around.
4305 </p>
4306 <p>
4307 By changing the paper size and the orientation you can change the size
4308 of the scratchboard as well. You can do so by just changing the
4309 dropdown field below, and the scratchboard will resize automatically,
4310 without interfering with the current placement of the elements.
4311 </p>
4312 <p>
4313 If ever an element gets out of range you can either enlarge the paper
4314 size or click on the 'reset' button to place all elements below each
4315 other.
4316 </p>
4321 <p> 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 <a href="http://wiki.phpmyadmin.net/pma/Charts#Data_formats_for_query_results_chart">wiki</a>.</p>

4339 existing language, where do I start?</a></h4>
4341 <p> Always use latest Git version of the po file to translate. You can optionally
4343 server</a> where you can also get the latest po files and merge them
4344 with your translations. For creating a new translation simply use
4348 to do this) or ask on the mailing list to add the translation to the web
4349 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Gettext_for_translators">our wiki</a>.
4350 </p>
4351 <p>
4352 Please note that we try not to use HTML entities like &eacute; in
4353 the translations, since we define the right character set in the file.
4354 With HTML entities, the text on JavaScript messages would not
4355 display correctly.
4356 However there are some entities that need to be there: quotes,
4357 non-breakable spaces, ampersands, less than, greater than.
4358 </p>
4359 <p>
4360 You can then put your translations, as a zip file to avoid losing special
4361 characters, on the sourceforge.net <a href="https://sourceforge.net/tracker/?group_id=23067&atid=387645">translation tracker.</a>
4362 </p>
4363 <p>
4364 It would be a good idea to subscribe to the <a href="https://lists.sourceforge.net/lists/listinfo/phpmyadmin-translators">phpmyadmin-translators</a> mailing
4365 list, because this is where we ask for translations of new messages.
4366 </p>
4368 <p>
4369 Documentation is being translated using po4a and gettext (see
4371 for existing translations). To start, checkout

4400 <p>More details on git are available on <a href="http://wiki.phpmyadmin.net/pma/Git">our wiki</a>.</p>
4402 <p> Write access to the repository is granted only to experienced developers who
4403 have already contributed something useful to phpMyAdmin.<br />
4409 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4411 <p> Please refer to

4413 </p>
4418 <p> If you use Apache web server, phpMyAdmin exports information about
4419 authentication to the Apache environment and it can be used in Apache logs.
4420 Currently there are two variables available:
4421 </p>
4422 <dl>
4424 <dd>User name of currently active user (he does not have to be logged
4425 in).</dd>
4432 </dl>
4433 <p>
4435 </p>
4436 <pre>
4439 </pre>
4440 <p>
4441 You can then use any log analyzing tools to detect possible break-in
4442 attempts.
4443 </p>
4449 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4450 It allows you to connect to local as well as remote servers. This requires you to enter
4451 server host name, username, password, port and the name of the database. Therefore you can
4452 now synchronize your databases placed on the same server or some remote server.
4453 </p>
4455 <p>
4456 This feature is helpful for developers who need to replicate their
4457 database’s structure as well as data. Moreover, this feature not only
4458 helps replication but also facilitates the user to keep his/her database
4459 in sync with another database. Other than the full database, certain
4460 tables of the databases can also be synchronized.
4461 </p>
4463 <p>
4464 You need to fill in the host name of the server, the username and
4465 password of an user account already there in MySQL. Port is by default
4466 populated with 3306 (MySQL default port). Then the name of the database
4467 should be mentioned at the end. All the information other than the port
4468 needs to be filled explicitly for the source as well as target servers.
4469 </p>
4471 <p>
4472 After successfully passing through the authentication phase, the source and
4473 target database table names will be displayed. It will be a tabular
4474 representation.
4475 </p>
4477 <p>
4478 On the left, are listed the source database table names. Some of the
4480 are only present in source database and they need to be added to the
4481 target database in order to synchronize the target database. The tables
4483 target database.
4484 </p>
4486 <p>
4487 On the right, are listed the target database table names. There are few
4489 means that these tables are to be created in target database in order to
4490 synchronize target database with source database. Some table names
4492 only present in target database and they will remain unchanged in the
4493 target database. The column in the middle shows the difference between
4494 the source and target corresponding tables.
4495 </p>
4497 <p>
4499 letters, indicating that either Structure or Data are not up to date. By
4500 clicking on them, they will turn grey, what means that they will be synchronized.

4882 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4883 to create a web-based interface to MySQL using PHP3. Although I have not
4884 used any of his source-code, there are some concepts I've borrowed from
4885 him. phpMyAdmin was created because Peter told me he wasn't going to
4886 further develop his (great) tool.
4887 </p>
4888 <p>
4889 Thanks go to
4890 </p>
4891 <ul>
4893 code for the check when dropping a table or database. He also suggested
4894 that you should be able to specify the primary key on tbl_create.php3. To
4895 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4896 well as a bug-report. Plus many smaller improvements.
4897 </li>
4899 were introduced in 1.3.0 (including quite significant ones like the
4900 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4901 bug-fixes and help.
4902 </li>
4904 language-independent by outsourcing the strings to a separate file. He
