In what scenarios would it be beneficial to use a separate menu for admin pages in PHP, and what are some best practices for implementing this feature?

It is beneficial to use a separate menu for admin pages in PHP to provide a clear distinction between regular user pages and admin pages, improve security by restricting access to admin functionalities, and enhance user experience for administrators. One best practice for implementing this feature is to create a separate menu file for admin pages and include it only when the user is logged in as an administrator.

<?php
// Check if user is logged in as an admin
if($isAdmin) {
    include 'admin_menu.php'; // Include separate menu for admin pages
}
?>
