Found other bug report indicating this is a Zend Optimizer issue. IMHO, an announcement should be made on the homepage indicating if you upgrade to PHP 4.3.10 you should also make sure you upgrade Zend Optimizer. On Thu, 16 Dec 2004 13:53:39 -0600, Jeremy Johnstone <phpdev@gmail.com> wrote:

The bug you have there is a Zend optimizer bug as you conclude yourself. So why bother the mailinglist with it? And yes, there is another foreach bug of you do: foreach($array as $key => $key) Derick

As you mentioned in the bug report, IMHO that isn't a bug. I can't think of any instance where this should be a valid syntax (maybe I am not thinking creatively enough).

It's ofcourse totally silly code ;-) Also, this was already in 4.3.1, so no critical thing at all. Atlest it doesn't "leak" in 4.3.10... So the only bug with foreach was in combination with the Zend Engine AFAIK. Derick

That's not a PHP bug. Its an issue with older versions of ZendOptimizer which is clearly stated in that bug report. Maybe we should print a warning on the download page since many PHP users seem to be experiencing it. Edin

That was my suggestion too as no previous subminor version release of PHP broke like this due to a Zend extension not being upgraded. I would expect things like this to happen on an upgrade from 4.2 to 4.3, but not on an upgrade from 4.3.9 to 4.3.10. With statements like "several very serious security issues" on the homepage, many are going to be quick to upgrade and won't learn of the possible issues which could occur if they don't upgrade Zend extensions too. --------------------------- Jeremy Johnstone http://www.jeremyjohnstone.com jsjohnst@php.net
