Sorry.
I back-flashed to nineteen-ninety-mumble when we were all using
register_globals, because there was no way to turn it off... :-)
Using $k = "K$i"; $v = $$k; was (slightly) easier on the typing
fingers than $HTTP_GET_VARS["K$i"]; back in those days...
It's still way easier to use an array in the HTML and let PHP build it
for you, though.
