In the above, if link was valid and returned something then $fp would be a string containing the HTML source of the $url. If the link was invalid (I'm not sure what exactly PHP would regard as an invalid link) then PHP would output a warning/error message (make sure you have error reporting set to an appropriately high level). file() implicitly opens and closes the file for you so no need for fclose(). -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* The rhino is a homely beast, For human eyes he's not a feast.
