How can the session ID be passed manually using the SID constant in a Location header in PHP?

To pass the session ID manually using the SID constant in a Location header in PHP, you can set the Location header with the SID constant appended to the URL. This can be useful when you need to redirect a user while maintaining their session across different pages.

<?php
session_start();

// Set the session ID in the Location header
header("Location: newpage.php?" . SID);
exit;
?>
