Maximum execution time of 300 seconds exceeded in code example

Example 1: maximum execution time of 120 seconds exceeded xampp

And Change xampp\php\php.ini to max_execution_time = 1000; or higher value

Example 2: Fatal error: Maximum execution time of 30 seconds exceeded

// you need to add this line at the bottom of your .htaccess file
Before # END WordPress Like this...

php_value max_execution_time 1000
# END WordPress

Example 3: Maximum execution time of 360 seconds exceeded

A better solution here is to change the config that controls phpMyAdmin and not the php.ini file.

If you change the php.ini file you effect everything in PHP and should you write that infinite loop that we all do from time to time it will take longer to terminate your infinite loop than is sensible.

Note: If you are using the 64bit WAMPServer the base folder name will be wamp64 instead of wamp so please amend the below folder names accordingly.

So change \wamp\alias\phpmyadmin.conf. By default it will look something like this although your version of phpMyAdmin will probably be different:

Alias /phpmyadmin "c:/wamp/apps/phpmyadmin4.1.14/"

<Directory "c:/wamp/apps/phpmyadmin4.1.14/">
   Options Indexes FollowSymLinks MultiViews
   AllowOverride all
  <IfDefine APACHE24>
    Require local
  </IfDefine>
  <IfDefine !APACHE24>
    Order Deny,Allow
      Deny from all
      Allow from localhost ::1 127.0.0.1
    </IfDefine>
  php_admin_value upload_max_filesize 128M
  php_admin_value post_max_size 128M
  php_admin_value max_execution_time 360
  php_admin_value max_input_time 360
</Directory>
To extend the maximum time limit for importing a database, change the php_admin_value max_execution_time parameter. You may also need to change the other parameters as larger databases tend to come in larger files and take longer to read as well. Example:

  php_admin_value upload_max_filesize 1024M
  php_admin_value post_max_size 1024M
  php_admin_value max_execution_time 1800
  php_admin_value max_input_time 1800
