What are best practices for debugging PHP scripts that do not produce any output?

If a PHP script is not producing any output, it could be due to errors in the code that are not being displayed. To debug this issue, you can enable error reporting in PHP to see any errors that are being generated. Additionally, you can use functions like error_log() to log errors to a file for further investigation.

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP code here
?>
