Actually there are ways to use integers as property names, but they are converted to strings on creation: https://3v4l.org/0k4LS and https://3v4l.org/HhPZP (also https://3v4l.org/Ts42B). ArrayAccess doesn't use magic __isset(string $name) but interface offsetExists(mixed $offset). Regards, -- Guilliam Xavier
