What are the differences in including files between local servers like Xamp and hosted servers like 1und1 in PHP?

When including files in PHP, the main difference between local servers like Xampp and hosted servers like 1und1 is the file path. Local servers typically use a relative path, while hosted servers may require an absolute path. To ensure compatibility across different servers, it's best to use the `__DIR__` constant to generate the correct path dynamically. 

<?php
include __DIR__ . '/file.php';
