Can PHP include files from a different server using absolute URLs?
PHP can include files from a different server using absolute URLs by enabling the `allow_url_include` directive in the php.ini configuration file. This directive allows PHP to include files from remote servers using URLs. However, it is important to note that this feature can pose security risks, so it should be used with caution.
<?php
ini_set('allow_url_include', 1);
include 'http://example.com/file.php';
?>
