You can use different PHP versions for different domains in your cPanel account. For example, you can assign one version to Example1 and another to Example2.
Log in to cPanel.
In the Software section, open MultiPHP Manager.
Scroll to the domain list. Select the checkbox beside the domain you want to change.
Choose the desired version from the PHP Version list, then click Apply.
Repeat these steps for each domain you want to configure. For example, select Example2 and choose PHP 5.6 if that version is available in the list.
Each domain will use the PHP version you applied to it.
