How can the error_reporting function be used to troubleshoot PHP variable passing issues?

When troubleshooting PHP variable passing issues, the error_reporting function can be used to display any notices or warnings related to variable scope or undefined variables. By setting the error_reporting level to include E_NOTICE or E_WARNING, any potential issues with variable passing can be identified more easily. This can help pinpoint where variables are not being passed correctly between different parts of the code. 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Code where variable passing issues may occur
// Ensure variables are properly defined and passed between functions or sections of code
?>
