Thus 0 == "" sould IMHO return true... > 0 == "" evaluating to true has been a footgun for me in the past; something like that: ```php $state = $_GET['state'] ?? null; // ... switch ($state) { case 0: // when $state === "", this branch is incorrectly chosen // ... } ``` where the state parameter comes from <select name="state"> and is supposed to provide an optional filter criterion for some list. The fact that both values are falsy doesn’t mean that they should be equal (hopefully, array() == 0 evaluates to false). —Claude
