PHP Info
From WHMCS Documentation
WHMCS is able to display a variety of information about your server and the current PHP configuration.
You can view this information at Utilities > System > PHP Info.
PHP Info
The information that the system displays includes information such as PHP options and extensions, the PHP version, server information, and php.ini configuration settings currently in use for the WHMCS Admin Area.
These details come directly from the phpinfo() PHP function and WHMCS does not edit or change them.
