What are the potential challenges of changing the working directory before including a file in PHP?

Changing the working directory before including a file in PHP can lead to issues with relative file paths not resolving correctly. To solve this, you can use absolute file paths or reset the working directory back to its original state after including the file. 

<?php
// Save the current working directory
$originalDirectory = getcwd();

// Change the working directory
chdir('/path/to/new/directory');

// Include the file
include 'file.php';

// Reset the working directory back to its original state
chdir($originalDirectory);
?>
