How to Upgrade PHP for WHMCS Using cPanel MultiPHP

In order to comply with each version's requirements, you must sometimes upgrade the PHP version on your WHMCS installation's server.

If you use cPanel and EasyApache 4 to host your WHMCS installation, you can use MultiPHP Manager and MultiPHP INI Editor to change your PHP version.

  • For the required pre-upgrade steps, see PHP Upgrade Guide.
  • For other control panels, consult the vendor's documentation.
  • For a full index of PHP compatibility by WHMCS version, see PHP Compatibility Guide.
