is php running as a module? if so did you restart the server.
this is a bit of a hack anyway!
Usually you would have all the paths worked out and stored /in the
application layer/ so that you are not resorting to workarounds, the
protabilty depends on a bit of string manipulation nothing more - to
find things like the document root.
For instance, replacing
$_SERVER["SCRIPT_NAME"]
inside
$_SERVER["SCRIPT_FILENAME"]
with the empty string, or '/'
str_replace(
$_SERVER["SCRIPT_NAME"],
'/',
$_SERVER["SCRIPT_FILENAME"] );
gets you the document root of the host you are on.
