Edit report at https://bugs.php.net/bug.php?id=79521&edit=1 ID: 79521 Comment by: carusogabriel@php.net Reported by: carusogabriel@php.net Summary: Fix __set_state documentation Status: Open Type: Documentation Problem Package: Class/Object related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: > It doesn't include __set_state, but this is likely just an oversight. Yeah, I'm working on that right now, that's why I come up with this bug report. > The return value is simply being ignored. Also not an error. It isn't: it does change the result based on the type: - https://3v4l.org/jt3jL (string) - https://3v4l.org/tIHi3 (object) This is supported by the engine: https://github.com/php/php-src/blob/d21d23afef54f152d9ca661909c6d042d6bfcf48/ext/standard/var.c#L472-L593 > and it is not an error to pass more arguments than are defined in a function signature. It is not an error, this is why the documentation needs to be updated, right? Previous Comments: ------------------------------------------------------------------------ [2020-04-26 03:06:10] requinix@php.net The fact that you can get away without arguments is for the usual reasons: the signature of __set_state is not enforced by the engine, and it is not an error to pass more arguments than are defined in a function signature. The return value is simply being ignored. Also not an error. Related: the magic-methods-signature RFC https://wiki.php.net/rfc/magic-methods-signature It doesn't include __set_state, but this is likely just an oversight.

Something like -static __set_state ( array $properties ) : object +static __set_state ( [array $properties] ) : mixed ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79521&edit=1
