In the Plesk interface, you and your customers can fine-tune the PHP
settings for individual service plans, add-on plans, subscriptions,
websites, and subdomains. One can change the values of some of the most

<parameter_group>is the group the chosen PHP parameter belongs
to. For more information about the groups of PHP parameters, read
“PHP parameters and parameter groups” below. -
