Bug #77302 [Asn->Csd]: Unserialize decode issue

Edit report at https://bugs.php.net/bug.php?id=77302&edit=1 ID: 77302 Updated by: nikic@php.net Reported by: sh at analogic dot cz Summary: Unserialize decode issue -Status: Assigned +Status: Closed Type: Bug Package: Variables related PHP Version: 7.3.0 Assigned To: dmitry Block user comment: N Private report: N New Comment: Closing this. PHP 7.4 implements https://wiki.php.net/rfc/custom_object_serialization as a robust custom serialization mechanism where usage of parent::__serialize / parent::__unserialize is safe. There is nothing actionable here beyond that.

But this is probably not PHP7.1+ syntax anyways. ------------------------------------------------------------------------ [2019-02-26 18:00:39] felix at moches dot de Thank you very much. ------------------------------------------------------------------------ [2019-02-21 11:08:52] nikic@php.net @felix: I've fixed this issue in https://github.com/php/php-src/commit/af324e24df85022314787f6dcf2ac811f58b88f3. ------------------------------------------------------------------------ [2019-02-21 10:50:09] nikic@php.net @felix: That's not quite the same bug, and something we can actually fix... I wasn't aware that returning null from Serializable::serialize() is a thing. This was allowed in https://github.com/php/php-src/commit/d77945ef78aead05a3adb6307ccedc12d0ca49ee, but I'm wondering why... Do you happen to know? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
