This article describes how to use Plesk to change the active PHP version and settings on an account.
PHP Selector allows users to see the currently selected PHP version. They can change PHP version, enable/disable PHP Extensions, and select modules they want to be available for their website, making the modules immediately available for the web application.
End-users can adjust the most important values, and control PHP Extensions such as (upload_max_filesize) and (post_max_size) without the need to modify any files like “php.ini” or “htaccess” manually – everything is done from the web interface.
