require a file in a parent directory

[Anon]

I have a file in a subdirectory that needs to include a file in the parent directory.

The code: require_once("../x.php") gives me an error indicating the file was not found.

My code only works if I take the file out of the subdirectory and place it in the same directory as x.php.

i always use:
require("$DOCUMENT_ROOT/path/to/file.inc");
which you can get from phpinfo()
