Plesk offers us the possibility of having several active versions of PHP on the server, in this way, it is possible to select the version we want in each subscription with total independence.

To do this, first it is necessary to access the subscription in which we want to select our version of PHP.

Once inside the subscription, we will have to look for "PHP configuration" in websites.

Here we can see the dropdown and we can select the PHP version that interests us the most.
