How about this:
     $parts = explode( '/', $_SERVER['SCRIPT_NAME'] );
     $something = $parts[ (count( $parts ) - 3 ) ];

     echo "something == $something";

You may want to put some error checking in there incase there aren't
enough directory levels in your path - this would cause $something to
be a null length string.
