How can absolute paths be implemented in include commands in PHP to avoid information loss?

When using include commands in PHP, using absolute paths instead of relative paths can help avoid information loss. Absolute paths specify the full path to the file, starting from the root directory, ensuring that the correct file is included regardless of the current working directory. This can be especially useful when including files from different directories or when moving files around.

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