What are the best practices for activating PHP on a Plesk server to ensure proper functionality of PHP scripts?

To ensure proper functionality of PHP scripts on a Plesk server, it is important to activate PHP and configure it correctly. This can be done by enabling PHP support in Plesk, selecting the desired PHP version, adjusting PHP settings such as memory_limit and max_execution_time, and ensuring that the necessary PHP modules are installed.

<?php
// Example PHP configuration settings
ini_set('memory_limit', '256M');
ini_set('max_execution_time', 60);
?>
