Bug #14266 Updated: serialize() doesn't work correcty

ID: 14266 User updated by: lenar@vision.ee Reported By: lenar@vision.ee Status: Bogus Bug Type: Scripting Engine problem Operating System: Debian Linux PHP Version: 4.2.0-dev New Comment: Ok, I tested a little bit more and found that when calling serialize() like serialize(&$x) it works. I know about leaks, but those leaks don't kill me (yet). And btw. Circular references work as expected. There is nothing so "undefined" about them in php. They work quite logically.

Circular refferences can happen with objects (using refferences). Sometimes they are intentional. And serialize() doesn't completely ignore this. Because it spits out: O:8:"stdClass":1:{s:1:"x";O:8:"stdClass":1:{s:1:"x";R:2;}} so it knows about circular refferences. Now is there any reason why it doesn't generate instead something like this: O:8:"stdClass":1:{s:1:"x";R:1;} I would understand if it completely ignores circular references, but it doesn't. It just misbehaves. ------------------------------------------------------------------------ [2001-11-28 08:41:04] jmoore@php.net Your creating a reference to itself this is not allowed. Therefore the bug is bogus, the behaviour is undefined. - James ------------------------------------------------------------------------ [2001-11-28 08:38:38] lenar@vision.ee Tested this with current cvs too. No better luck. Original and unserialized objects have different representation in memory. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
