Comment:

 Thanks for the report @kesselb. In PHP,
 [https://www.php.net/manual/en/language.types.void.php void is a special
 return type which indicates that the function returns nothing]. It's not a
 real type, therefore it gets coerced to `null` as in your example, but
 `void` is the correct type here.

 Cheers!
