i think telnet might have been an option too, .. but i'm not sure how to call a page with telnet. if you were able to, then you wouldn't need php to call the script.
the file() function reads a file ( local or remote ) into an array. each line of the file is a seperate element of the arrray.
we don't really care about the array, just that it calls the file to try to read it. that just tells the php script to execute.
on the telnet subject though, i could connect to a server with telnet mydomain.com 80 .. then i tried to get a page with: GET index.php , but that didn't work.
so if you don't mind installing php on all the clients, then that may be the best solution.
