How to set another default PHP version for new subscriptions?
Currently new domains are being created with unwanted PHP version.
For created subscription PHP version can be changed in Hosting Settings :
Subscriptions > example.com > Websites & Domains > Hosting Settings > PHP version
To change PHP version for all new subscriptions, PHP version should be set under Service plan section. By default,
Default Domainplan is used.
Service Plans > < service_plan_name > > Hosting Parameters > PHP version
If Plesk edition does not allow to manage service plans via web interface (Web Admin Edition, Web App Edition) it can be managed by command line utilities. For example for Plesk 12.5 for Linux it can be done as follows:
Find hosting plan assigned to subscription:
# plesk bin subscription -i example.com | grep plan
The domain is subscribed to the service plan "Unlimited" of admin.
Find installed PHP handlers:
# /usr/local/psa/admin/bin/php_handlers_control --list
Set required PHP handler for hosting plan:
# plesk bin service_plan -u "Unlimited" -php_handler_id plesk-php70-fpm
The hosting plan 'Unlimited' was successfully updated.
