New Comment:
I think solution 2 would be better since that would also allow caching objects:
public static function __cast($id)
{
if (!isset(self::$cache[$id]))
self::$cache[$id] = new self($id);
return self::$cache[$id];
}

If we have both casting (the other one being #46128) then perhaps the names
should be __castFrom() and castTo(). Or perhaps even __castFromInt() and
castToInt() and so on.

Not a dupe: request #46128 covers casting the other way. (That alone is
probably a good argument for changing the proposed magic method name.)

pretty nice, awesome feature!
but i have some recommendations on this:
1) is it true that i cannot cast to a boolean false? what about throwing the
error if no return was made? the user is able to throw some exception or will
simple not return anything to use the default error mechanism...
2) i think there should be 2 additional types of functions covering your 2
solutions by simply change the name. for your case 1 this should be __cast,
whereas 2 could be __hint? the essential difference is that __hint will be
called in the functions arguments and __cast will be called elsewhere?

@degeberg: Doesn't the RFC cover casting the other way round? I.e. Class ->
Scalar
