Req #52182 [Opn->Bgs]: get_object_by_id and get_object_id

Edit report at http://bugs.php.net/bug.php?id=52182&edit=1 ID: 52182 Updated by: johannes@php.net Reported by: olamedia at gmail dot com Summary: get_object_by_id and get_object_id -Status: Open +Status: Bogus Type: Feature/Change Request Package: Unknown/Other Function PHP Version: 5.3.2 New Comment: Your design looks broken. Why should unset a random pointer to the object destroy it? If you really need to unset them - which I'd most likely consider broken design - add a method to invalidate it this ... If you really want to do this the needed function is available - spl_object_hash(). But mind that we don't have any true unique identifier - once an object is destroyed it's ID might be re-used by others.
