What are common issues with PHP sessions when dealing with users who have cookies enabled or disabled?

One common issue with PHP sessions when dealing with users who have cookies disabled is that the session ID will not persist between page loads. To solve this, you can use URL rewriting to pass the session ID in the URL parameters.

<?php
// Start the session
session_start();

// Check if the session ID is passed in the URL
if(isset($_GET['PHPSESSID'])) {
    session_id($_GET['PHPSESSID']);
}

// Continue with your code
?>
