Where is php.ini in WordPress?

The php.ini file isn’t specifically related to WordPress, but to the PHP language itself. WordPress, like many other applications, is built using PHP. The php.ini file is the default configuration file for running applications that require PHP. It controls many aspects such as resource limits, extensions to load, and more.

Now, the location of php.ini can vary depending on your hosting environment, and the specific configuration of the server where your WordPress site is hosted. Generally, you’ll find it in one of these places:

  1. On a shared hosting server: You might not have direct access to the php.ini file because of security reasons. In such cases, you may be able to override some PHP settings using a .user.ini file or php5.ini file in your website’s root directory (public_html). You might also be able to change some settings via cPanel or similar hosting control panel software. If you’re not sure, it’s best to contact your hosting provider for more information.
  2. On a VPS/Dedicated Server with standard PHP installation: The php.ini file can usually be found in a directory like /etc/php/[version]/cli/ or /etc/php/[version]/apache2/, where [version] is your PHP version number.
  3. If you’re using a server with a control panel like cPanel/WHM or Plesk: The php.ini file can usually be found in a location like /usr/local/lib/php.ini or /etc/php.ini.
  4. On a local server (like WAMP, XAMPP, MAMP): You’ll usually find the php.ini file in the PHP folder of your server software.
    • For WAMP: it’s usually located in C:\wamp\bin\php\php[version], where [version] is your PHP version number.
    • For XAMPP: it’s usually located in C:\xampp\php\php.ini.
    • For MAMP: it’s typically in /Applications/MAMP/bin/php/php[version]/conf, where [version] is your PHP version number.

To edit the php.ini file, you would typically use a text editor if you have file system access, or the editing tools provided by your hosting control panel.

Remember to backup the php.ini file before making any changes, because incorrect settings can disrupt your server. After making changes, you’ll usually need to restart your web server or PHP service for changes to take effect. If you’re not sure how to do this, or if you’re uncomfortable making these changes, you should ask your hosting provider for assistance or hire a professional.

If you’re having trouble locating your php.ini file, you can create a PHP file with the phpinfo() function to locate it:


Name it something like info.php, upload it to your web root (public_html), and then access it in your web browser by navigating to www.yourdomain.com/info.php. Look for the ‘Loaded Configuration File’ line in the output, which will show you the exact path of the php.ini file being used. Don’t forget to delete this file after you’re done, as it contains sensitive information about your server.
