What are the potential challenges of including links from a PHP script in a different directory?

When including links from a PHP script in a different directory, the main challenge is ensuring that the paths to the linked files are correct. One solution is to use the `__DIR__` magic constant to get the absolute path of the current directory and then construct the path to the linked file relative to that. 

<?php
include __DIR__ . '/../path/to/linked_file.php';
?>
