I've just stumbled upon that weird behavior when force casting the return of a function to an object. The PHP result was not what I expected.
$a = null;
echo empty($a) ? "Yes, I'm empty" : "You should not see this"This is pretty straighforward code. Now, we test it with an object.
$a = (object) null;
echo empty($a) ? "Yes, I'm empty" : "You should not see this but, actually, you do."Note that it even gets weirder when (object) false and (object) true become objects with a key scalar, set to false
This is one of the little things that make me want to ditch PHP for a better language.
