#27833 [Asn->Csd]: Concatenating overloaded objects fails (works in PHP6, but not in 5.1)

ID: 27833 Updated by: tony2001@php.net Reported By: steph dot fox at virgin dot net -Status: Assigned +Status: Closed Bug Type: Scripting Engine problem Operating System: * PHP Version: 5CVS-2004-04-02 (dev) Assigned To: helly New Comment: Implemented in 5_2, won't be backported to 5_1.

Note that this does not affect internal extensions such as SimpleXML who require this to work in order to be useful. The main problem with supporting automatic __toString() calls is the fact that opcodes aren't reentrant and it requires restructuring of some of the infrastructure of the engine. Looking into this is on my TODO for post-stable 5.0. Can't promise anything though. ------------------------------------------------------------------------ [2004-04-03 08:16:06] steph dot fox at virgin dot net OK, I did my research now. Sadly run-tests doesn't work on win98 due to the piping element, but I found that building PHP with zend_std_cast_object_tostring included as part of the std_object_handlers struct gets rid of all the issues & doesn't cause any new issues in ext/simplexml's test batch. (I ran them manually). Of course the other new extensions that use std_object_handlers might be adversely affected, but it's override-able (no?). It's such an easy fix (must be if I can find it!), I'm obviously missing the reason that the cast_object property's currently set as NULL. The internals list archives show a huge discussion on the subject, most of which goes straight over my head. Just looking for clarity now.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
