What are some common debugging techniques for PHP code to identify issues with maintaining design consistency?

Issue: One common debugging technique for maintaining design consistency in PHP code is to check for syntax errors or typos that may be causing inconsistencies in the design. This can be done by using a syntax checker tool or enabling error reporting in PHP to identify any issues.

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

// Your PHP code here
?>
