inoerdrt to pass vaiables to an including file....varialbes should be defined before the include file statement..
eg:-
if u want to pass var and var2 ... consider the following :-
$var=$value;
$var2=$value;
include("path/includedfile.php");
-- this wont work--------
include(\\\"path/includedfile.php?var=$value&var2=$value\\\");
