I was reminded tonight of the following 'feature' of switch:

$a = 0;
switch($a) {
case 'somestring': echo 'Bug?'; break;
case 0: echo 'Not a bug'; break;
}

This will echo 'Bug?' with PHP 4. It seems more logical to
have switch
comparing with T_IS_IDENTICAL than with T_IS_EQUAL. Is this
something that
might be changed as we move to PHP 5.0?>
It's not a 'feature', it's a feature. It's not likely to
change, dynamic
type conversion is one of the foundations of PHP.

Well, yes, but we have == and === for other situations, so some sort of
analogue for use in switches would be nice (I've been bitten by this one
more than once myself!).

I'd love to see, say, case_identical for requesting an === comparison, with
case continuing as before to do an == comparison.

Cheers!
