How can error reporting in PHP be effectively used to debug scripts and identify issues like unset variables or global scope problems?

To effectively use error reporting in PHP to debug scripts and identify issues like unset variables or global scope problems, you can set error_reporting to E_ALL at the beginning of your script to display all types of errors. Additionally, enabling display_errors in your php.ini file will show errors directly on the screen, making it easier to identify and fix issues. 

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

// Your PHP script code here
?>
