How can you troubleshoot issues with require_once not properly including a PHP file in your script?

If `require_once` is not properly including a PHP file in your script, you should first check the file path to ensure it is correct. Make sure the file exists and has the correct permissions. You can also try using `dirname(__FILE__)` to get the current directory path and then concatenate the file name to ensure the correct file path is used. 

<?php
// Check the file path
require_once('/path/to/your/file.php');

// Use dirname(__FILE__) to get the current directory path
require_once(dirname(__FILE__) . '/file.php');
?>
