Jesus man.

case statements not followed by a break; statement fall through.

Your code should read:

<? $k = "+";
   switch($k) {
     case "-": print "Oh no!"; break;
     case "+": print "Correct!"; break;
   }
?>

<? $k = "+";
   switch($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?
