How can error_reporting be used to debug issues with PHP code?

To debug issues with PHP code, the error_reporting function can be used to display errors and warnings directly on the webpage. By setting the error_reporting level to E_ALL, all errors and warnings will be displayed, helping to identify and fix issues in the code.

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

// Your PHP code here
?>
