How can the difference between server file paths and URL paths impact including files in PHP?

When including files in PHP, it's important to note that server file paths and URL paths are not the same. Server file paths refer to the physical location of the file on the server, while URL paths are used to access files through a web browser. To ensure that files are included correctly, always use server file paths when including files in PHP. 

<?php
include $_SERVER['DOCUMENT_ROOT'] . '/path/to/file.php';
?>
