The system default PHP version can be changed in the MultiPHP Manager in WHM. This setting determines the version of PHP assigned to any new account that you create. Changing this setting does not alter any account’s PHP version, unless it is set to inherit its PHP version from the system.
1. Log into WHM.
2. Navigate to MultiPHP Manager.
3. Under System PHP Version, click Edit next to the current system default PHP version.
4. Select the desired version of PHP.
5. Click Apply to change the system default PHP version to the selected PHP version.
