Oh come on Andi, are you telling me you can't do everything at once?
Yes, I don't care about which one is the non-set variable. I'd be glad to
help on making this function work like that, but I'm afraid my C is rusty
enough to require Tetanus shots for everyone involved. :) (Okay so it isn't
really that bad.)
Well, I remember reading that someone suggested making it so that any
negative number was false. So if that was the case and I did the following:
$a = 1;
$b = 2;
$d = 4;
$play_nice = isSet($a, $b, $c, $d);
if (!$play_nice) {
print "The variable missing is in position ";
print ($play_nice*-1);
}
And it would print 3, in which case we would know $c is not set. I'm not
that sure about this approach, seems like a hack, but the
I-don't-care-which-one-isn't-set approach seems fine to me.
Maybe a poll?
(X) Extend the isset() and empty() functions to encompass multiple
variables as one inclusive logic test.
