php需要使用root的功能

Question

I have a site with several sub folders and an include folder in the root:

for example :

www.mysite.com 
www.mysite.com/includes 
www.mysite.com/includes/inc.php

then a sub folder:

www.mysite.com/sub1/
www.mysite.com/sub1/page.php

in page.php I would like to include the inc.php which is in the includes folder. Is that possible, and if so, how can i do that? (tried $_SERVER["DOCUMENT_ROOT"] and didn't work.)

I appreciate the responses, it is quite urgent as I need to move the site to a new server in this format!!!! thanks everyone!

Answer 1

I can't think of why document root isn't working but when you do find out, use like this... Have you tried echoing $_SERVER["DOCUMENT_ROOT"] to see what it outputs?

<?php

define(ROOT, '/home/www/web18/html');

require_once ROOT.'/includes/inc.php';

?>

Also, run... <?php phpinfo();?>

There should be root path somewhere...
