setting the document root path in linux

[tbt]

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

Don't rely on document root.

I'm surprised it worked on windows, you were lucky - 90% of the time
it's not there or not correct anyway.

If it's in the same directory as the current file, do:

require(dirname(__FILE__) . '/includes/class.announcement.php');

__FILE__ is a built in constant that tells you the full path to the
current file.

dirname() takes the filename out of that and gives you just the current
directory (see http://www.php.net/dirname ).

Then add the rest of the on the end.

are you running apache on windows and linux?

if so, setup a .htaccess file that has a line in it that modifies the php include path

place that .htaccess at your web root and you won't have to play with paths, you would call
        require_once 'includes/class.announcement.php';   instead

Fix your include paths and you wont have to worry if the system will have what it should in the
$_SERVER['DOCUMENT_ROOT'].
