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

151 </ul>
154 <p> Many people have difficulty
155 understanding the concept of user management with regards to phpMyAdmin. When
156 a user logs in to phpMyAdmin, that username and password are passed directly
157 to MySQL. phpMyAdmin does no account management on its own (other than
158 allowing one to manipulate the MySQL user account information); all users
159 must be valid MySQL users.</p>
168 <!-- INSTALLATION -->
176 </ol>
179 phpMyAdmin does not apply any special security methods to the MySQL database
180 server. It is still the system administrator's job to grant permissions on
182 be used for this.
183 </p>
191 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
192 before uploading them to your server, as PHP seems not to like
197 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
198 Downloads page. Some kits contain only the English messages,
199 others contain all languages in UTF-8 format (this should be fine
200 in most situations), others contain all
201 languages and all character sets. We'll assume you chose a kit whose
203 </li>
204 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
206 document root. If you don't have direct access to your document root,
207 put the files in a directory on your local machine, and, after step 4,
208 transfer the directory on your web server using, for example, ftp.</li>
209 <li>Ensure that all the scripts have the appropriate owner (if PHP is
210 running in safe mode, having some scripts with an owner different
211 from the owner of other scripts will be a
216 <li>Now you must configure your installation. There are two methods that
217 can be used. Traditionally, users have hand-edited a copy of
219 provided for those who prefer a graphical installation. Creating a
220 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
221 <ul><li>To manually create the file, simply use your text editor to
224 file) in the main (top-level) phpMyAdmin directory (the one
228 default value is okay for a particular setting, there is no
230 few directives to get going, a simple configuration may look
231 like this:
232 <pre>
233 <?php
234 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
236 $i=0;
237 $i++;
238 $cfg['Servers'][$i]['auth_type'] = 'cookie';
239 ?>
240 </pre>
241 Or, if you prefer to not be prompted every time you log in:
242 <pre>
243 <?php
245 $i=0;
246 $i++;
247 $cfg['Servers'][$i]['user'] = 'root';
248 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
249 $cfg['Servers'][$i]['auth_type'] = 'config';
250 ?>
251 </pre>
252 For a full explanation of possible configuration values, see the
258 directory. This is a security measure. On a Linux/Unix system you
259 can use the following commands:
260 <pre>
261 cd phpMyAdmin
262 mkdir config # create directory for saving
263 chmod o+rw config # give it world writable permissions
264 </pre>
265 And to edit an existing configuration, copy it over first:
266 <pre>
267 cp config.inc.php config/ # copy current configuration for editing
268 chmod o+w config/config.inc.php # give it world writable permissions
269 </pre>
270 On other platforms, simply create the folder and ensure that your
279 the webserver does not have the proper permissions you may see the
281 config/</tt> directory exists and has the proper permissions -
283 and upload (via FTP or some similar means) to the proper location.<br /><br />
285 Once the file has been saved, it must be moved out of the <tt>
286 config/</tt> directory and the permissions must be reset, again
287 as a security measure:
288 <pre>
289 mv config/config.inc.php . # move file to current directory
290 chmod o-rw config.inc.php # remove world read and write permissions
291 rm -rf config # remove not needed directory
292 </pre>
293 Now the file is ready to be used. You can choose to review or edit
294 the file with your favorite editor, if you prefer to set some
295 advanced options which the setup script does not provide.</li></ul></li>
296 <li>If you are using the
298 protect the phpMyAdmin installation directory because using
299 config does not require a user to
300 enter a password to access the phpMyAdmin installation. Use of an alternate
301 authentication method is recommended, for example with
309 in your browser. phpMyAdmin should now display a welcome screen
310 and your databases, or a login dialog if using
312 authentication mode.</li>
315 Apache you can use supplied .htaccess file in that folder, for other
316 webservers, you should configure this yourself. Such configuration
317 prevents from possible path exposure and cross side scripting
318 vulnerabilities that might happen to be found in that code.</li>
319 <li>
320 It is generally good idea to protect public phpMyAdmin installation
321 against access by robots as they usually can not do anything good
323 your webserver or limit access by web server configuration. You can

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

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

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

548 The Swekey is a low cost authentication USB key that can be used in
549 web applications.<br /><br />
550 When Swekey authentication is activated, phpMyAdmin requires the

552 supported for cookie authentication mode only). Swekey Authentication is
553 disabled by default.<br /><br />

948 cursor over the corresponding key.<br />
949 This configuration variable will hold the name of this special
950 table. To allow the usage of this functionality:
952 <li>put the table name in
954 'pma_table_info')</li>

995 Starting with release 2.5.0, comments are consequently used on the table
996 property pages and table browse view, showing up as tool-tips above the
997 column name (properties page) or embedded within the header of table in
998 browse view. They can also be shown in a table dump. Please see the
999 relevant configuration directives later on.<br /><br />
1001 Also new in release 2.5.0 is a MIME-transformation system which is also
1003 Transformations</a> for further information. To use the
1004 MIME-transformation system, your column_info table has to have the three
1005 new columns 'mimetype', 'transformation', 'transformation_options'.

1034 all queries you entered manually into the phpMyAdmin interface. If you
1035 don't want to use a table-based history, you can use the JavaScript-based
1036 history. Using that, all your history items are deleted when closing the
1037 window.<br /><br />
1039 Using
1041 you can specify an amount of history items you want to have on hold. On
1042 every login, this list gets cut to the maximum amount.<br /><br />

1060 Since release 3.3.x a tracking mechanism is available.
1062 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1063 and data definition statements. After enabling it you can create versions of tables.
1064 <br/><br/>
1065 The creation of a version has two effects:
1067 <ul>
1069 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1070 </ul>
1072 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1073 For the report you can use filters, for example you can get a list of statements within a date range.
1074 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1075 In addition you can export the (filtered) report to a file or to a temporary database.

1882 Explorer.If set to 'fake' PHP does the transformation for you, but of

2045 or icon is always displayed on the left panel. If JavaScript is enabled in
2046 your browser, a click on this opens a distinct query window, which is
2047 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2048 changes to display a query box.<br /><br />

2061 <br /><br />
2062 The usage of the JavaScript query window is recommended if you have a
2063 JavaScript enabled browser. Basic functions are used to exchange quite
2064 a few variables, so most 4th generation browsers should be capable to
2065 use that feature. It currently is only tested with Internet Explorer 6

2074 When using the JavaScript based query window, it will always get
2075 updated when you click on a new table/db to browse and will focus if
2076 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2077 the query window by checking the box "Do not overwrite this query from
2078 outside the window" below the query textarea. Then you can browse
2079 tables/databases in the background without losing the contents of the
2080 textarea, so this is especially useful when composing a query with
2081 tables you first have to look in. The checkbox will get automatically
2082 checked whenever you change the contents of the textarea. Please

2117 where you edit x/y coordinates of those elements you can activate a
2118 scratchboard where all your elements are placed. By clicking on an
2119 element, you can move them around in the pre-defined area and the x/y
2120 coordinates will get updated dynamically. Likewise, when entering a
2121 new position directly into the input field, the new position in the
2122 scratchboard changes after your cursor leaves the input field.<br />
2123 You have to click on the 'OK'-button below the tables to save the new
2124 positions. If you want to place a new element, first add it to the
2125 table of elements and then you can drag the new element around.<br />
2126 By changing the paper size and the orientation you can change the size
2127 of the scratchboard as well. You can do so by just changing the
2128 dropdown field below, and the scratchboard will resize automatically,

2338 <!-- TRANSFORMATIONS -->
2344 </ol>
2348 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2350 section</a> on how to do so.</p>
2352 <p> You can apply different transformations to the contents of each column. The
2353 transformation will take the content of each column and transform it with
2354 certain rules defined in the selected transformation.</p>
2356 <p> Say you have a column 'filename' which contains a filename. Normally you would
2357 see in phpMyAdmin only this filename. Using transformations you can transform
2358 that filename into a HTML link, so you can click inside of the phpMyAdmin
2359 structure on the column's link and will see the file displayed in a new browser
2360 window. Using transformation options you can also specify strings to
2361 append/prepend to a string or the format you want the output stored in.</p>
2363 <p> For a general overview of all available transformations and their options,
2364 you can consult your
2365 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2366 installation.</p>
2368 <p> For a tutorial on how to effectively use transformations, see our
2370 the official phpMyAdmin homepage.</p>
2374 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2375 clicking on the 'Structure' link for a table). There click on
2376 "Change" (or change icon) and there you will see three new
2377 fields at
2378 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2379 'Transformation options'.</p>
2381 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2382 that corresponds to the column's contents. Please note that
2383 transformations are inactive as long as no MIME-type is selected.</li>
2385 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2386 hopefully growing amount of pre-defined transformations. See below for information on
2387 how to build your own transformation.<br />
2389 There are global transformations and mimetype-bound transformations. Global transformations
2390 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2391 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2392 transformations which operate on the main mimetype (like 'image'), which will most likely
2393 take the subtype into regard, and those who only operate on a
2394 specific subtype (like 'image/jpeg').<br />
2396 You can use transformations on mimetypes for which the function was not defined for. There
2397 is no security check for you selected the right transformation, so take care of what the
2398 output will be like.</li>
2400 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2401 transform-function specific options here. Usually the transforms can operate with default
2402 options, but it is generally a good idea to look up the overview to see which options are
2403 necessary.<br />
2405 Much like the ENUM/SET-Fields, you have to split up several options using the format
2406 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2407 parsed as an array, leaving the first value the first element in the array, and so
2408 forth.<br />
2410 If you want to specify a MIME character set you can define it in the transformation_options.
2411 You have to put that outside of the pre-defined options of the specific mime-transform,
2413 for which you can specify 2 options and you want to append a character set, enter "'first
2414 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2416 </ul>
2420 <p> All mimetypes and their transformations are defined through single files in
2421 the directory 'libraries/transformations/'.</p>
2423 <p> They are stored in files to ease up customization and easy adding of new
2424 transformations.</p>
2426 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2427 always work. It makes no sense to apply a transformation to a mimetype the
2428 transform-function doesn't know to handle.</p>
2430 <p> One can, however, use empty mime-types and global transformations which should work
2431 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2432 for, but pay attention to option usage as well as what the transformation does to your
2433 column.</p>
2435 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2436 any other transform function and provides some basic functions.</p>
2438 <p> There are 5 possible file names:</p>
2440 <ol><li>A mimetype+subtype transform:<br /><br />
2442 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2444 Please not that mimetype and subtype are separated via '_', which shall
2445 not be contained in their names. The transform function/filename may
2446 contain only characters which cause no problems in the file system as
2447 well as the PHP function naming convention.<br /><br />
2449 The transform function will the be called
2450 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2452 <b>Example:</b><br /><br />
2454 <tt>text_html__formatted.inc.php</tt><br />
2455 <tt>PMA_transform_text_html__formatted()</tt></li>
2457 <li>A mimetype (w/o subtype) transform:<br /><br />
2459 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2461 Please note that there are no single '_' characters.
2462 The transform function/filename may contain only characters which cause
2463 no problems in the file system as well as the PHP function naming
2464 convention.<br /><br />
2466 The transform function will the be called
2467 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2469 <b>Example:</b><br /><br />
2471 <tt>text__formatted.inc.php</tt><br />
2472 <tt>PMA_transform_text__formatted()</tt></li>
2474 <li>A mimetype+subtype without specific transform function<br /><br />
2476 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2478 Please note that there are no '__' characters in the filename. Do not
2479 use special characters in the filename causing problems with the file
2480 system.<br /><br />
2482 No transformation function is defined in the file itself.<br /><br />
2484 <b>Example:</b><br /><br />
2486 <tt>text_plain.inc.php</tt><br />
2487 (No function)</li>
2489 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2491 <tt>[mimetype].inc.php</tt><br /><br />
2493 Please note that there are no '_' characters in the filename. Do not use
2494 special characters in the filename causing problems with the file system.
2495 <br /><br />
2497 No transformation function is defined in the file itself.<br /><br />
2499 <b>Example:</b><br /><br />
2501 <tt>text.inc.php</tt><br />
2502 (No function)</li>
2504 <li>A global transform function with no specific mimetype<br /><br />
2506 <tt>global__[transform].inc.php</tt><br /><br />
2508 The transform function will the be called
2509 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2511 <b>Example:</b><br /><br />
2513 <tt>global__formatted</tt><br />
2514 <tt>PMA_transform_global__formatted()</tt></li>
2515 </ol>
2517 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2518 transform function.</p>
2520 <p> All filenames containing no '__' in themselves are not shown as valid transform
2521 functions in the dropdown.</p>
2523 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2524 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2525 without a transform function.</p>
2527 <p> To create a new transform function please see
2528 <tt>libraries/transformations/template_generator.sh</tt>.
2529 To create a new, empty mimetype please see
2530 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2532 <p> A transform function always gets passed three variables:</p>
2534 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2535 you want to transform.</li>
2536 <li><b>$options</b> - Contains any user-passed options to a transform function
2537 as an array.</li>
2538 <li><b>$meta</b> - Contains an object with information about your column.
2539 The data is drawn from the output of the
2541 function. This means, all object properties described on the
2543 available in this variable and can be used to transform a column accordingly
2544 to unsigned/zerofill/not_null/... properties.<br />
2545 The $meta->mimetype variable contains the original MIME-type of the
2546 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2547 </ol>
2549 <p> Additionally you should also provide additional function to provide
2550 information about the transformation to the user. This function should
2551 have same name as transformation function just with appended
2552 <code>_info</code> suffix. This function accepts no parameters and returns
2553 array with information about the transformation. Currently following keys
2554 can be used:
2555 </p>
2556 <dl>
2557 <dt><code>info</code></dt>
2558 <dd>Long description of the transformation.</dd>

2633 <p> This seems to be a PWS bug. Filippo Simoncini found a workaround (at this
2634 time there is no better fix): remove or comment the <tt>DOCTYPE</tt>

2645 PHP functions to be more independent of the platform (Unix/Windows, Safe Mode

2653 <p> Your uploaded file is saved by PHP in the "upload dir", as
2654 defined in <i>php.ini</i> by the variable <tt>upload_tmp_dir</tt> (usually
2655 the system default is <i>/tmp</i>).<br />
2656 We recommend the following setup for Apache servers running in safe mode,
2657 to enable uploads of files while being reasonably secure:</p>
2659 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2660 <li>give ownership to the Apache server's user.group:
2661 <tt>chown apache.apache /tmp/php</tt></li>
2662 <li>give proper permission: <tt>chmod 600 /tmp/php</tt></li>
2663 <li>put <tt>upload_tmp_dir = /tmp/php</tt> in <i>php.ini</i></li>
2664 <li>restart Apache</li>

2672 <p> It's not really phpMyAdmin related but RedHat 7.0. You have a RedHat 7.0
2673 and you updated your PHP RPM to php-4.0.4pl1-3.i386.rpm, didn't you?<br />
2674 So the problem is that this package has a serious bug that was corrected
2675 ages ago in PHP (2001-01-28: see
2677 for more details). The problem is that the bugged package is still
2678 available though it was corrected (see
2680 for more details).<br />

2736 were named <tt>user</tt> and <tt>password</tt>. Please modify your column
2737 names to align with current standards.</p>
2742 </h4>
2744 <p> Starting with version 2.7.0, the import engine has been re–written and these
2745 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2746 to take advantage of the new import features.</p>
2748 <p> The first things to check (or ask your host provider to check) are the
2749 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2750 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2751 All of these three settings limit the maximum size of data that can be
2752 submitted and handled by PHP. One user also said that post_max_size
2753 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2755 There exist several workarounds if your upload is too big or your
2756 hosting provider is unwilling to change the settings:</p>

2766 or any third party applications, but are aware of users having success
2767 with it.</li>
2768 <li>If you have shell (command line) access, use MySQL to import the files
2769 directly. You can do this by issuing the "source" command from
2770 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2771 </ul>
2775 support?</a></h4>
2777 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2778 older MySQL versions, you need to use 2.8.x branch. phpMyAdmin can
2779 connect to your MySQL server using PHP's classic
2782 is available in php 5.0. The latter one should be used unless you have
2783 good reason not to do so.<br />
2784 When compiling php, we strongly recommend that you manually link the MySQL
2785 extension of your choice to a MySQL client library of at least the same
2786 minor version since the one that is bundled with some PHP distributions is
2789 If your webserver is running on a windows system, you might want to try
2790 MySQL's

2800 <p> You tried to access MySQL with an old MySQL client library. The version of
2801 your MySQL client library can be checked in your phpinfo() output.
2802 In general, it should have at least the same minor version as your server

2831 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2832 "MySQL extension". This extension may be part of the PHP
2833 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2834 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2835 to load the extension but failed.<br /><br />
2837 Usually, the problem is solved by installing a software package called
2838 "PHP-MySQL" or something similar.</p>

2858 <p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
2859 defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
2860 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2861 Just edit your <tt>my.ini</tt> file that should be located in your Windows
2862 directory and add the following line to the group [mysqld]:</p>
2864 <pre>set-variable = lower_case_table_names=0</pre>
2866 <p> Next, save the file and restart the MySQL service. You can always check the
2867 value of this directive using the query</p>

2885 </pre>
2887 <p> as this version of mod_gzip on Apache (Windows) has problems handling
2888 PHP scripts. Of course you have to restart Apache.</p>
2893 I get the error "No input file specified" when trying to
2894 run phpMyAdmin.</a></h4>
2896 <p> This is a permission problem. Right-click on the phpmyadmin folder

2909 PHP 5.0.0.</p>
2913 message 'Errorcode: 13'. What does this mean?</a></h4>
2915 <p> This can happen due to a MySQL bug when having database / table names with
2916 upper case characters although <tt>lower_case_table_names</tt> is set to 1.
2917 To fix this, turn off this directive, convert all database and table names
2918 to lower case and turn it on again. Alternatively, there's a bug-fix
2919 available starting with MySQL 3.23.56 / 4.0.11-gamma.</p>
2923 and the columns are duplicated.</a></h4>
2925 <p> It is possible to configure Apache in such a way that PHP has problems
2926 interpreting .php files.</p>
2928 <p> The problems occur when two different (and conflicting) set of directives
2929 are used:</p>
2931 <pre>
2932 SetOutputFilter PHP
2933 SetInputFilter PHP
2934 </pre>
2936 <p> and</p>

2940 <p> In the case we saw, one set of directives was in
2941 <tt>/etc/httpd/conf/httpd.conf</tt>, while
2942 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2943 The recommended way is with <tt>AddType</tt>, so just comment out
2944 the first set of lines and restart Apache:</p>
2946 <pre>
2947 #SetOutputFilter PHP
2948 #SetInputFilter PHP

2995 Table and script parts are optional. If you want

3000 <code>Options FollowSymLinks</code> and <code>AllowOverride

3036 password encryption in cookie auth doesn't work.</a></h4>
3038 <p> If your cluster consist of different architectures, PHP code used for
3039 encryption/decryption won't work correct. This is caused by use of
3040 pack/unpack functions in code. Only solution is to use mcrypt extension
3041 which works fine in this case.</p>
3046 <p> Yes but the default configuration values of Suhosin are known to cause
3047 problems with some operations, for example editing a table with many
3048 columns and no primary key or with textual primary key.
3049 </p>
3050 <p>
3051 Suhosin configuration might lead to malfunction in some cases and it can
3052 not be fully avoided as phpMyAdmin is kind of application which needs to
3053 transfer big amounts of columns in single HTTP request, what is something
3054 what Suhosin tries to prevent. Generally all
3055 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3056 <code>suhosin.get.*</code> directives can have negative effect on
3057 phpMyAdmin usability. You can always find in your error logs which limit
3058 did cause dropping of variable, so you can diagnose the problem and adjust
3059 matching configuration variable.
3060 </p>
3061 <p>
3062 The default values for most Suhosin configuration options will work in most
3063 scenarios, however you might want to adjust at least following parameters:

3091 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3093 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />
3094 Example from the Apache 2.2 documentation:</p>
3095 <pre>
3096 ProxyPass /mirror/foo/ http://backend.example.com/
3097 ProxyPassReverse /mirror/foo/ http://backend.example.com/
3098 ProxyPassReverseCookieDomain backend.example.com public.example.com

3100 </pre>
3102 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3103 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
3104 This is not specific to phpmyadmin, it's just the behavior of Apache.

3149 connect to local MySQL server through socket '/tmp/mysql.sock'
3150 (111) ..." is displayed. What can I do?</a></h4>
3152 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3154 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3155 In your <i>php.ini</i> you will find a line</p>
3157 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3159 <p> change it to</p>
3161 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3163 <p> Then restart apache and it will work.</p>
3165 <p> Here is a fix suggested by Brad Ummer:</p>
3167 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3168 To do this, telnet to your server and go to the MySQL bin directory. In
3169 this directory there should be a file named <i>mysqladmin</i>. Type
3170 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3171 info about your MySQL server, including the socket
3172 (<i>/tmp/mysql.sock</i>, for example).</li>
3173 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3174 phpMyAdmin, you need to complete the socket information in the
3175 <i>config.inc.php</i>.<br />
3176 For example:
3178 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3179 <br /><br />
3181 Please also make sure that the permissions of this file allow to be readable
3182 by your webserver (i.e. '0755').</li>

3187 corresponding section of the MySQL documentation</a>.</p>

3197 it means you're running a beta version of PHP. That's not a so good idea,
3198 please upgrade to a plain revision.</p>
3202 or a table, an error 404 (page not found) is displayed or, with <abbr title="HyperText Transfer Protocol">HTTP</abbr> or
3203 cookie authentication, I'm asked to log in again. What's wrong?</a></h4>
3205 <p> Check the value you set for the
3207 directive in the phpMyAdmin configuration file.</p>
3211 password: YES)"-error when trying to access a MySQL-Server on a
3212 host which is port-forwarded for my localhost.</a></h4>
3214 <p> When you are using a port on your localhost, which you redirect via
3215 port-forwarding to another host, MySQL is not resolving the localhost
3216 as expected.<br />
3217 Erik Wasser explains: The solution is: if your host is "localhost"
3218 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3219 connection for speeding up things. And that doesn't work in this configuration
3220 with port forwarding.<br />
3226 <p> Themes are configured with
3230 <br />
3232 should not delete the directory "original" or its underlying
3233 structure, because this is the system theme used by phpMyAdmin.
3234 "original" contains all images and styles, for backwards
3235 compatibility and for all themes that would not include images or css-files.
3236 <br /><br />
3239 is enabled, you can select your favorite theme on the main page. Your
3240 selected theme will be stored in a cookie.<br /><br /></p>
3242 <p> To create a theme:</p>
3244 <ul><li>make a new subdirectory (for example "your_theme_name") under
3246 (by default <tt>themes</tt>)</li>
3247 <li>copy the files and directories from "original" to
3248 "your_theme_name"</li>
3249 <li>edit the css-files in "your_theme_name/css"</li>
3250 <li>put your new images in "your_theme_name/img"</li>
3251 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3252 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3253 contain your chosen theme name, that will be visible in user interface</li>
3254 <li>make a new screenshot of your theme and save it under
3255 "your_theme_name/screen.png"</li>
3256 </ul>
3258 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3259 theme verbose name, theme generation and theme version. These versions and
3260 generations are enumerated from 1 and do not have any direct dependence on
3261 phpMyAdmin version. Themes within same generation should be backwards
3262 compatible - theme with version 2 should work in phpMyAdmin requiring
3263 version 1. Themes with different generation are incompatible.</p>
3265 <p> If you do not want to use your own symbols and buttons, remove the
3266 directory "img" in "your_theme_name". phpMyAdmin will
3267 use the default icons and buttons (from the system-theme "original").
3268 </p>
3272 what can I do?</a></h4>
3274 <p> Here are a few points to check:</p>
3276 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3278 directive empty. See also
3280 </li>
3281 <li>Maybe you have a broken PHP installation or you need to upgrade
3282 your Zend Optimizer. See
3284 http://bugs.php.net/bug.php?id=31134</a>.
3285 </li>
3286 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3287 set to the default (200) or another low value, you could get this
3288 error if your table has a high number of columns. Adjust this setting
3289 accordingly. (Thanks to Klaus Dorninger for the hint).
3290 </li>
3291 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3292 of ";" will cause this error. Replace it with "&;".
3293 </li>
3295 you might want to increase
3297 </li>
3298 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3299 </li>
3300 </ul>
3305 <p> To be able to see a progress bar during your uploads, your server must
3308 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3309 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3316 who logged out can not log in again in with the same nick.</a></h4>
3318 <p> This is related to the authentication mechanism (protocol) used by
3319 phpMyAdmin. To bypass this problem: just close all the opened
3320 browser windows and then go back to phpMyAdmin. You should be able to
3321 log in again.</p>
3325 limit error or a time limit error.</a></h4>
3327 <p> Compressed dumps are built in memory and because of this are limited to
3328 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3329 using
3331 (enabled by default). Zip exports can not be handled this way, so if you need
3332 Zip files for larger dump, you have to use another way.</p>
3336 when I rename a table or a column.</a></h4>
3338 <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>
3342 bundled with the MySQL server distribution.</a></h4>
3344 <p> The problem is that older versions of <code>mysqldump</code> created invalid comments like this:</p>
3346 <pre>
3347 -- MySQL dump 8.22
3348 --
3349 -- Host: localhost Database: database
3350 ---------------------------------------------------------
3351 -- Server version 3.23.54
3352 </pre>
3354 <p> The invalid part of the code is the horizontal line made of dashes that
3355 appears once in every dump created with mysqldump. If you want to run your
3356 dump you have to turn it into valid MySQL. This means, you have to add a
3357 whitespace after the first two dashes of the line or add a # before it:
3358 <br />
3359 <code>
3360 -- -------------------------------------------------------<br />
3361 </code>
3362 or<br />
3363 <code>
3364 #---------------------------------------------------------
3365 </code>
3366 </p>
3373 <p> Please note that you should not use the separating string multiple times
3374 without any characters between them, or at the beginning/end of your table
3375 name. If you have to, think about using another TableSeparator or disabling
3376 that feature</p>
3381 <p> In Relation view, being able to choose a table in another database,
3382 or having more than one index column in the foreign key.<br /><br/>

3384 LEFT JOIN from the foreign table.<br /><br/>
3385 </p>
3389 I get series of errors like "Warning: unable to parse url". How
3390 can this be fixed?</a></h4>
3391 <p>
3392 Your table neither have a primary key nor an unique one, so we must use a
3393 long expression to identify this row. This causes problems to parse_url
3394 function. The workaround is to create a primary or unique key.
3395 <br />
3396 </p>
3400 a MIME-Transformation onto!</a></h4>
3402 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3403 nested forms can be put inside the table where phpMyAdmin displays the results.
3404 You can, however, use any form inside of a table if keep the parent
3405 form-container with the target to tbl_row_delete.php and just put your own
3406 input-elements inside. If you use a custom submit input field, the form will
3407 submit itself to the displaying page again, where you can validate the
3408 $HTTP_POST_VARS in a transformation.
3410 For a tutorial on how to effectively use transformations, see our
3412 on the official phpMyAdmin-homepage.</p>
3416 MySQL server</a></h4>
3418 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3421 http://dev.mysql.com/doc/mysql/en/ANSI_mode.html</a>). Most important of all,
3422 the quote-character (") is interpreted as an identifier quote character and
3423 not as a string quote character, which makes many internal phpMyAdmin
3425 statements. There is no workaround to this behaviour. News to this item will
3426 be posted in Bug report
3427 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>
3428 </p>
3432 more that one column with the same value
3433 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3434 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3436 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3437 can use it for the Edit and Delete links.</p>
3442 <p> phpMyAdmin uses a quick method to get the row count, and this method
3443 only returns an approximate count in the case of InnoDB tables. See
3445 a way to modify those results, but
3446 this could have a serious impact on performance.</p>
3451 <p> The number of records in queries containing COUNT and GROUP BY is
3452 not correctly calculated. Also, sorting results of a query like
3457 containing an hyphen.
3458 </a></h4>
3459 <p>
3460 The tests I have made with current MySQL 4.1.11 API shows that the
3461 API does not accept this syntax for the USE command. Enclosing the
3462 db name with backquotes works. For further confusion, no backquotes
3463 are needed with command-line mysql.

3467 <a href="#faq3_14">3.14 I am not able to browse a table when I don't have the right to SELECT one of the columns.</a></h4>
3468 <p>
3469 This has been a known limitation of phpMyAdmin since the beginning and
3470 it's not likely to be solved in the future.
3471 </p>
3473 <!-- Begin: Excel import limitations -->
3476 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3477 <p>
3478 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/" target="_blank">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3479 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3480 <br /><br />
3481 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3485 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3486 <p>
3487 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3488 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3489 </p>
3492 <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>
3493 <p>
3494 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3495 consider using a built-in type. These are almost always guarenteed to import correctly.
3496 </p>
3498 <!-- End: Excel import limitations -->
3499 <!-- Begin: CSV import limitations -->
3502 <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>
3503 <p>
3504 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.

3511 <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>
3512 <p>
3513 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
3514 you will have to edit the structure to your liking post-import.
3515 <br /><br />
3516 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
3517 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.

3964 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3965 <p>
3968 <br /><br />
3969 Then you need to think about your schema layout. Which tables will go on
3970 which pages?
3971 </p>
3972 <ul>
3978 page and click Go. If you like, you
3980 linked tables onto the new page.</li>
3981 <li>Select the name of the new page (making sure the Edit radio button
3982 is selected) and click Go.</li>
3984 Coordinates are relative; your diagram will
3985 be automatically scaled to fit the page. When initially placing tables
3986 on the page, just pick any coordinates -- say, 50x50. After clicking
3988 position the element correctly.</li>
3990 first be sure to click the Save
3991 button beneath the list of tables and coordinates, to save any changes
3992 you made there. Then scroll all the way down, select the
3994 you want, and click Go.</li>
3995 <li>Internet Explorer for Windows may suggest an incorrect filename when
4000 browsers on Windows, do not have this problem.</li>
4001 </ul>
4005 columns!</a></h4>
4007 <p> No, it's MySQL that is doing
4013 underscores in the database name?</a></h4>
4015 <p> If you do not put a backslash before the underscore, this is a wildcard
4018 john2db ...<br /><br />
4020 If you put a backslash before the underscore, it means that the database
4021 name will have a real underscore.</p>
4025 statistics pages?</a></h4>
4036 if it already exists during the import. It does NOT drop the table after
4037 your export, it only affects the import file.</li>
4039 Otherwise, you may get an error if the table name exists but has a
4040 different structure.</li>
4042 (if any) will be included in backup.</li>
4044 column and table names formed with special characters are protected.</li>
4046 types set in the pmadb in the dump as
4048 </li>
4049 </ul>
4054 command, for better documentation (but resulting file is bigger).</li>
4056 once the INSERT verb and the table name.</li>
4059 </li>
4061 more info is provided in the
4063 but basically with this selected, invalid values are adjusted and
4064 inserted rather than causing the entire statement to fail.</li>
4065 </ul>
4069 in its name.</a></h4>
4072 is the normal way to reference a database and table name. Worse, MySQL
4073 will usually let you create a database with a dot, but then you cannot
4074 work with it, nor delete it.</p>
4080 <p>
4081 To use SQL Validator, you need PHP with
4087 module.
4088 </p>
4090 <p>
4096 usage.
4097 </p>
4099 <p>
4100 If you use the Validator, you should be aware that any
4102 submit will be stored anonymously (database/table/column names,
4103 strings, numbers replaced with generic values). The Mimer
4106 We utilize it as free SOAP service.
4107 </p>
4111 it, but MySQL says "BLOB column '...' used in key specification without
4114 <p> The right way to do this, is to create the column without any indexes,
4116 dialog. On this page, you will be able to choose your BLOB column, and
4117 set a size to the index, which is the condition to create an index on
4118 a BLOB column.</p>
4122 editing fields?</a></h4>
4124 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4125 with many editing fields (table structure changes, row editing, etc.)
4126 (must be enabled in configuration - see.
4128 You can also have a look at the directive
4130 ('vertical') and see if this eases up editing for you.</p>
4134 WTF is this feature then useful for?</a></h4>
4136 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4137 on them. Otherwise you could just put a comment on the column. Because entering
4138 your own mimetype will cause serious syntax checking issues and validation,
4139 this introduces a high-risk false-user-input situation. Instead you have to
4140 initialize mimetypes using functions or empty mimetype definitions.<br />
4141 Plus, you have a whole overview of available mimetypes. Who knows all those
4142 mimetypes by heart so he/she can enter it at will?</p>
4146 can't I see any bookmarks below the query box? What is this variable for?
4147 </a></h4>
4149 <p> Any query you have executed can be stored as a bookmark on the page where the
4150 results are displayed. You will find a button labeled 'Bookmark this query'
4151 just at the end of the page.<br />
4152 As soon as you have stored a bookmark, it is related to the database you run
4153 the query on. You can now access a bookmark dropdown on each page, the query
4154 box appears on for that database.<br /><br />
4156 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4160 aware of that you HAVE to create a valid query, otherwise your query won't be
4161 even able to be stored in the database.<br />
4163 for your query will remain the way it is, but will be stripped of the /**/
4164 chars. So you can use:<br /><br />
4168 which will be expanded to<br /><br />
4172 in your query, where VARIABLE is the string you entered in the input box. If
4173 an empty string is provided, no replacements are made.<br /><br />
4175 A more complex example. Say you have stored this query:<br /><br />
4177 <br /><br />
4180 the full query will be:<br /><br />
4183 <br /><br />
4187 spaces inserted there
4188 will be later also inserted as spaces in your query and may lead to unexpected
4189 results especially when
4191 Your initial query which is going to be stored as a bookmark has to yield at
4192 least one result row so
4193 you can store the bookmark. You may have that to work around using well
4197 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4198 include exported table?</a></h4>
4200 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4201 document should look like following one (assuming you have table
4204 <pre>
4205 \documentclass{article} % or any class you want
4206 \usepackage{longtable} % for displaying table
4207 \begin{document} % start of document
4208 \include{table} % including exported table
4209 \end{document} % end of document
4210 </pre>
4214 access them.
4215 </a></h4>
4217 <p> You have one of these global privileges: CREATE
4218 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4219 enable users to see all the database names.
4222 So if your users do not need those privileges, you can remove them and their
4223 databases list will shorten.</p>
4227 possible values for a column, based on some foreign table?</a></h4>
4229 <p> You have to setup appropriate links between the tables, and also
4233 foreign table, a drop-down list of values will be available.
4234 You will see two lists of values, the first list containing the key
4235 and the display column, the second list containing the display column
4236 and the key. The reason for this is to be able to type the first
4237 letter of either the key or the display column.<br /><br />
4239 For 100 values or more, a distinct window will appear, to browse foreign
4240 key values and choose one. To change the default limit of 100, see
4241 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4245 automatically when entering Browse mode for a table?</a></h4>
4247 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4248 </p>
4252 Excel files, how can I enable that?</a></h4>
4254 <p> You can use
4256 which works out of the box, but phpMyAdmin supports direct export
4257 to Microsoft Excel version 97 and newer. For this to work, you need to set
4262 <pre>
4263 cd phpMyAdmin
4264 mkdir tmp
4265 chmod o+rwx tmp
4266 </pre>
4270 what happens to my column comments stored in pmadb?</a></h4>
4272 <p> Automatic migration of a table's pmadb-style column comments to the native
4273 ones is done whenever you enter Structure page for this table.</p>
4278 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4279 <ul>
4282 later)</li>
4285 </ul>
4289 <ol>
4290 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of "localhost".</li>
4291 <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>
4292 <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>
4293 <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>
4294 </ol>
4299 <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>
4305 <p>
4306 In all places where phpMyAdmin accepts format strings, you can use
4309 expanded variables depend on a context (for example, if you haven't chosen a
4310 table, you can not get the table name), but the following variables can be used:
4311 </p>
4312 <dl>
4318 <dd>Verbose MySQL server name as defined in <a href="#cfg_Servers_verbose">server configuration</a></dd>
4329 </dl>

4343 </p>
4347 existing language, where do I start?</a></h4>
4349 <p> Always use latest Git version of the po file to translate. You can optionally
4351 server</a> where you can also get the latest po files and merge them
4352 with your translations. For creating a new translation simply use
4356 to do this) or ask on the mailing list to add the translation to the web
4357 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Devel:Gettext_for_translators">our wiki</a>.
4358 </p>
4359 <p>
4360 Please note that we try not to use HTML entities like &eacute; in
4361 the translations, since we define the right character set in the file.
4362 With HTML entities, the text on JavaScript messages would not
4363 display correctly.
4364 However there are some entities that need to be there: quotes,
4365 non-breakable spaces, ampersands, less than, greater than.
4366 </p>
4367 <p>
4368 You can then put your translations, as a zip file to avoid losing special
4369 characters, on the sourceforge.net <a href="https://sourceforge.net/tracker/?group_id=23067&atid=387645">translation tracker.</a>
4370 </p>
4371 <p>
4372 It would be a good idea to subscribe to the <a href="https://lists.sourceforge.net/lists/listinfo/phpmyadmin-translators">phpmyadmin-translators</a> mailing
4373 list, because this is where we ask for translations of new messages.
4374 </p>
4376 <p>
4377 Documentation is being translated using po4a and gettext (see
4379 for existing translations). To start, checkout
4380 <a href="http://phpmyadmin.git.sourceforge.net/git/gitweb.cgi?p=phpmyadmin/localized_docs;a=tree;f=po"><code>localized_docs/po</code></a>
4381 from Git, or just go to the <a href="https://l10n.cihar.com/projects/pmadoc/">translation server</a>
4382 and translate it online. If your language is missing, just contact
4384 you prefer to directly translate the po files, please put updated ones into our

4390 phpMyAdmin. How should I proceed?</a></h4>
4395 <tt>git clone

4397 </li>
4399 <li>generate patch with your changes:

4405 </li>
4406 </ol>
4408 <p>More details on git are available on <a href="http://wiki.phpmyadmin.net/pma/Devel:Git">our wiki</a>.</p>
4410 <p> Write access to the repository is granted only to experienced developers who
4411 have already contributed something useful to phpMyAdmin.<br />
4417 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4419 <p> Please refer to
4420 <a href="http://www.phpmyadmin.net/home_page/security.php">http://www.phpmyadmin.net/home_page/security.php</a>
4421 </p>
4426 <p> If you use Apache web server, phpMyAdmin exports information about
4427 authentication to the Apache environment and it can be used in Apache logs.
4428 Currently there are two variables available:
4429 </p>
4430 <dl>
4432 <dd>User name of currently active user (he does not have to be logged
4433 in).</dd>
4440 </dl>
4441 <p>
4443 </p>
4444 <pre>
4447 </pre>
4448 <p>
4449 You can then use any log analyzing tools to detect possible break-in
4450 attempts.
4451 </p>
4457 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4458 It allows you to connect to local as well as remote servers. This requires you to enter
4459 server host name, username, password, port and the name of the database. Therefore you can
4460 now synchronize your databases placed on the same server or some remote server.
4461 </p>
4463 <p>
4464 This feature is helpful for developers who need to replicate their
4465 database’s structure as well as data. Moreover, this feature not only
4466 helps replication but also facilitates the user to keep his/her database
4467 in sync with another database. Other than the full database, certain
4468 tables of the databases can also be synchronized.
4469 </p>
4471 <p>
4472 You need to fill in the host name of the server, the username and
4473 password of an user account already there in MySQL. Port is by default
4474 populated with 3306 (MySQL default port). Then the name of the database
4475 should be mentioned at the end. All the information other than the port
4476 needs to be filled explicitly for the source as well as target servers.
4477 </p>
4479 <p>
4480 After successfully passing through the authentication phase, the source and
4481 target database table names will be displayed. It will be a tabular
4482 representation.
4483 </p>
4485 <p>
4486 On the left, are listed the source database table names. Some of the
4488 are only present in source database and they need to be added to the
4489 target database in order to synchronize the target database. The tables
4491 target database.
4492 </p>
4494 <p>
4495 On the right, are listed the target database table names. There are few
4497 means that these tables are to be created in target database in order to
4498 synchronize target database with source database. Some table names
4500 only present in target database and they will remain unchanged in the
4501 target database. The column in the middle shows the difference between
4502 the source and target corresponding tables.
4503 </p>
4505 <p>
4507 letters, indicating that either Structure or Data are not up to date. By
4508 clicking on them, they will turn grey, what means that they will be synchronized.

4855 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4856 to create a web-based interface to MySQL using PHP3. Although I have not
4857 used any of his source-code, there are some concepts I've borrowed from
4858 him. phpMyAdmin was created because Peter told me he wasn't going to
4859 further develop his (great) tool.
