How can absolute paths be utilized in PHP include statements to prevent issues with file loading on different servers?

When using relative paths in PHP include statements, the file loading may not work correctly on different servers due to differences in file structures. To prevent this issue, absolute paths can be used in include statements to ensure that the correct file is always loaded regardless of the server environment.

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