What are potential reasons for a PHP script not producing any output or errors when executed?

One potential reason for a PHP script not producing any output or errors when executed is that error reporting may be disabled in the PHP configuration. To solve this issue, you can enable error reporting by setting the error_reporting level to E_ALL and displaying errors by setting display_errors to On in your PHP script.

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

// Your PHP script code here
?>
