Question
How to change PHP settings in Plesk?
Answer
-
Go to Domains > example.com > PHP Settings.
Note: To allow Plesk resellers/customers customize PHP settings for their domains, visit this KB article.
-
Adjust PHP settings according to your needs and apply the changes. Click on a value field to set a custom value.
-
Go to Service Plans > plan_name > PHP Settings.
-
Adjust PHP settings according to your needs and click Update & Sync.
Note: New settings will not be applied to existing subscriptions, if:
- A subscription is locked from syncing with its service plan.
- Permissions settings allow PHP management in this service plan. To revoke them, visit this KB article.
-
Go to Tools & Settings > PHP Settings > click on a required PHP version (any application) > switch to the php.ini tab.
-
Adjust values for existing PHP parameters or specify your own. Once done, apply the changes.
Note: Customized PHP settings configured on a domain level override directives in php.ini file. To make a domain use values from global PHP configuration, in domain's PHP settings click Reset To Default next to PHP parameters.
