How to reset a system-level PHP configuration (default php.ini)

Introduction

The system-level PHP configurations cannot be reset to the default values from WHM. However, it can be done through the command line.

Procedure

Please note that, in the following commands, "##" must be replaced with the PHP version (i.e., 74 for 7.4, 80 for 8.0, 81 for 8.1, etc.).

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Move the php.ini file out of the way for the PHP version to reset.

   mv -vi /opt/cpanel/ea-php##/root/etc/php.ini{,.$(date +%s)}

3. Reinstall the ea-php##-php-common package.
