The = operator takes precedence, and $d is set to 0.
But why? According to the manual, the modulus operator has
precedence over the equals! So shouldn't this expression resolve
to: ($s % $d) = 0 which gives an error?
Ya got me there.
I hadn't even checked the precedence list before answering.
Unless somebody has a rational explanation, I think this should be an
error...
When a similar anomaly involving the ! operator was reported (http://bugs.php.net/bug.php?id=17180), the response was that PHP is "smart" about such things and invokes the DWIM principle to silently alter the precedence of = in certain situations. This resulted in the addition of a note to the end of the operator precedence page at http://uk2.php.net/manual/en/language.operators.php#language.operators.precedence, but it seems to me that this is too specific to the ! operator and should be generalized. In fact, I'd completely forgotten that I suggested as much at the end of the bug report -- but this hasn't been taken up, so maybe a bunch of you want to re-activate the bug report and support my suggestion??
Cheers!
