What are some best practices for debugging PHP scripts to pinpoint errors or inconsistencies?

Issue: When debugging PHP scripts, it is important to utilize error reporting functions such as error_reporting(E_ALL) and ini_set('display_errors', 1) to display any errors or warnings that may occur. Additionally, using tools like Xdebug or PHP's built-in functions like var_dump() or print_r() can help pinpoint the source of errors or inconsistencies in the code. Code snippet:

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