$_SERVER['DOCUMENT_ROOT'] -
Is there anyway to figure this out if you dont have any idea what it is. My server changed it on me from what it used to be.
/export/home/b/bl/blfelber/public_html
simple way to get all your SERVER vars
echo "<pre>"; print_r($_SERVER); echo "</pre>";
See you steeings (also the server vars) by using this php script:
<?php phpinfo(); ?>
