How to set the PHP version per domain!
The MultiPHP Manager allows you to define separately per domain the version of PHP you will use.
1- Go to your hosting's cPanel in the "Software" section and look for the item "Multi PHP Manager" as in the image:

**2-**This screen will list all your domains. Select the domain you want to change in the checkbox, so that you don't change the PHP version of a domain you don't want.
Note: Only "ea-" versions of PHP are supported

After setting the version, a success message should be displayed.

Note: Now that the PHP version has been defined, if you need to make adjustments to the PHP directives, simply use the "MultiPHP INI Editor" item in your cPanel
