__isset() and null value

isset() returns false for null __isset() should return the same, but then if magic property with null value exists, there is no way to detect it Example: https://3v4l.org/GqUsh this is currently an limitation of php Ideally, we should introduce __exist() which should return true even if value is null and for BC autoimplement __isset() based on it and __get, ie. function __isset($n) { return $this->__exist($n) && $this->__isset($n) !== null; } With kind regards / Mit freundlichen Grüßen / S přátelským pozdravem, Michael Voříšek
