What could be causing the issue of an existing session cookie not being utilized in PHP scripts?

The issue of an existing session cookie not being utilized in PHP scripts could be caused by the session not being properly started or the cookie not being set with the correct parameters. To solve this issue, ensure that session_start() is called at the beginning of the script and that the session cookie is set with the correct parameters such as the path and domain. 

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

// Set the session cookie parameters
session_set_cookie_params(0, '/', '.example.com', false, true);

// Your PHP code here
?>
