How can one effectively troubleshoot PHP scripts that do not display errors but do not function as expected?

One effective way to troubleshoot PHP scripts that do not display errors but do not function as expected is to enable error reporting in the PHP configuration or in the script itself. This can be done by setting the error_reporting directive to E_ALL and display_errors directive to On. Additionally, checking for syntax errors, ensuring proper variable scope, and using debugging tools like var_dump() can help identify the issue. 

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

// Your PHP script code here

?>
