PHP Version and Configuration

Changing PHP version or PHP Settings

Before changing PHP versions, check which PHP versions are available. If the one you want isn’t available, contact your hoster.

The process of changing your PHP version is server-specific:

  • Some hosts running cPanel provide MultiPHP Manager tool
  • Some hosts running cPanel provide PHP Selector
  • Some hosts use a php.ini file

The process of changing PHP settings is also server-specific:

  • Some hosts running cPanel provide MultiPHP INI Editor
  • Some hosts running cPanel provide PHP Selector which has a page for configuring PHP settings
  • Some hosts use a php.ini file

Your hoster likely provides a knowledge base with instructions. Contact your hoster if you are unsure how to proceed.

If you want to run multiple versions of PHP on your server (for example, to keep a live site going with an older version and test an upgrade with a newer version), see Multiple PHP Versions.

Once you are done changing PHP version or a PHP setting, use the Version link on the top right navigation menu to confirm that the change you made is recognized by Zen Cart.
