Bug description: switch() problem: "+" matches "-"
<? $k = "+";
switch($k) {
case "-": print "Oh no!";
case "+": print "Correct!";
}
?>
outputs "Oh no!". I guess this is because as switch uses
==, + and - are both being automatically converted to the
number 0 which then matches? Could switch() perhaps use
=== instead of == in its comparison?
