setting the document root path in linux

Hi I'm a newbie to php and I'm using require_once($_SERVER['DOCUMENT_ROOT']."/includes/class.announcement.php"); to import pages in php. This works fine on a windows environment. However when I move this application to a linux environment the files dont get imported properly. This is because in a windows environment $_SERVER['DOCUMENT_ROOT'] returns c:/xampp/htdocs etc. but in a linux environment returns /home/servers etc. How can this be rectified so that the path is properly picked up in a linux environment -- View this message in context: http://www.nabble.com/setting-the-document-root-path-in-linux-tf4479174.html#a12771923 Sent from the PHP - General mailing list archive at Nabble.com.
