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

- Change the default value for a PHP parameter.
- Forbid specifying custom values for PHP parameters.
Determining what predefined values a PHP parameter can take
For most PHP parameters, one can select a single value from a list of

[php]
settings.<parameter_group>.<parameter_name>.values[]=<value>
where
-
<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. -
<parameter_name>is the name of the chosen PHP parameter. Use the
same syntax as in php.ini. -
<value>is the predefined value of the parameter you want to add
to the list. Use the same syntax as in php.ini.
You need to add one line for every predefined value you want to appear
