Note Submitter: marsh at NOSPAM-TAKETHATSPAMMER dot uri ---- The solution advanced by info at meshkaat dot com does not work correctly on machines with IIS configured to use a virtual directory as the launch point. The address strings for $_SERVER['SCRIPT_FILENAME'] and $_SERVER['PHP_SELF'] will not necessarily have the same name for the highest level directory in $_SERVER['PHP_SELF'], and therefore this solution will not return the proper value.
