What are the potential pitfalls of using absolute file paths in PHP?

Using absolute file paths in PHP can make your code less portable and more prone to errors if the file structure changes. To avoid these pitfalls, it's better to use relative file paths instead. This way, your code will be more flexible and easier to maintain. 

// Instead of using absolute file paths like this:
include('/var/www/html/includes/config.php');

// Use relative file paths like this:
include('includes/config.php');
