How can the URL be effectively passed from one menu file to a sub-menu file in PHP?

To pass the URL effectively from one menu file to a sub-menu file in PHP, you can use sessions or query parameters. Sessions allow you to store data across multiple pages for a specific user, while query parameters allow you to pass data through the URL. Both methods can be used to pass the URL from the menu file to the sub-menu file seamlessly. 

// Menu file
session_start();
$_SESSION['url'] = 'http://example.com/page';

// Sub-menu file
session_start();
$url = isset($_SESSION['url']) ? $_SESSION['url'] : '';
echo $url;
