File download Problem

when using readfile, please lookup the php manual for that function:
http://php.net/manual/en/function.readfile.php

"A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the List of Supported Protocols/Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide."

cheers!
