class ufo { const MP_SIZE_LARGE = 600; const MP_SIZE_MEDIUM = 400; const MP_SIZE_SMALL = 250; const LARGE = 'LARGE'; const MEDIUM = 'MEDIUM'; const SMALL = 'SMALL'; public $mp_size; public function desired_width() { switch ( $this->mp_size ) { case ufo::LARGE : return ufo::MP_SIZE_LARGE; case ufo::MEDIUM : return ufo::MP_SIZE_MEDIUM; case ufo::SMALL : return ufo::MP_SIZE_SMALL; default: return 0; } } } So check out the class and function above. What should "desired width" return if mp_size is 0? It makes no sense that the value is anything but 0. Instead, it returns 600. In fact, it will return 400 if I put the "medium" case first. Why would it do that? The function returns expected values if I put strval() around the mp_size. Can someone explain that? This makes absolutely no sense to me. I can't see how the order of the cases could possibly matter, and I also can't see how any case would be "true" when 0 doesn't equal "LARGE".

Hi, I want to set a variable based on the contents of another variable - I think I've see CASE used for this before but not entirely sure. Basically I'm trying to tidy this up: if ($var1 = "1") { $var2 = "a" } if ($var1 = "2" ) { $var2 = "b" } if ($var1 = "3") { $var2 = "c" } Any help appreciated. Thanks.
