RE: [PHP-DEV] feature request

I don't think that in that context, that semantics makes much sense. isset() for multiple variables as a 'all or nothing' checking method makes sense. But if you want to know which variable failed, use multiple isset()'s. As for negative numbers, they are and are to stay boolean true values. Zeev At 10:07 19/3/2001, Chris Newbill wrote:

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.

But I also need to think about how much sense it makes :) Today you're asking for isset(...,...,...). Tomorrow you will ask to know which one was not set if it failed. So I hope what youreally want is only the first. Andi At 09:42 PM 3/18/2001 -0500, Mike Robinson wrote:

This would not be a bad idea IMHO and I would use it for some things. The functionality would be inclusive not exclusive. So isset($var1, $var2, $var3) would only return true if $var1, $var2, and $var3 are

set and false

otherwise. So If I had a form passing $name, $email, $phone: example #1 if (isSet($name, $email, $phone)) // ALL GOOD Instead of example #2 if ((isSet($name)) &&

    (isSet($email)) &&
    (isSet($phone)))
    // ALL GOOD

Granted if one variable wasn't set, then you might run into some minor issues if you want to figure out which one is not set. But

that is the

developers choice. :) It wouldn't break existing functionality, seems simple enough

to implement

(although my karma is limited to doc's so someone else would have to do it), and would make some people happy. That seems to be reason enough to do it. Just my 2 cents.

Ditto. It would be handy. If you are willing and able to do stuff like this, maybe a request for additional karma would be in order.
