How can debugging tools like error_reporting be utilized to troubleshoot PHP code that involves session variables?

When troubleshooting PHP code that involves session variables, debugging tools like error_reporting can be utilized to display any errors or warnings related to session handling. By setting error_reporting to E_ALL, any issues with session variables not being set or accessed correctly will be displayed, helping to pinpoint the problem. Additionally, using functions like session_start() and session_unset() can help manage session variables effectively. 

<?php
error_reporting(E_ALL);

session_start();

// Access session variables
$_SESSION['username'] = 'JohnDoe';

// Unset session variables
session_unset();

// Destroy the session
session_destroy();
?>
