Are there any best practices to follow when including files in PHP scripts?

When including files in PHP scripts, it is best practice to use the `require_once` or `include_once` functions to ensure that the file is only included once to prevent any conflicts or errors. This helps to maintain code integrity and organization by avoiding duplicate declarations or functions. 

<?php
require_once 'file.php';
// rest of your PHP script
?>
