Hi Marcus,
Thanks for your clear answer :). What are the future plans concerning this issue? Will I be able to just extend this class as I want? For which version is that planned? The answers to these questions heavily influence design choices I have to make now.
Oh, and I'm curious why the article on Zend.com mentions that extendability is a key feature of mysqli. Even though it cannot be extended.. :)

Hello Bert,
some of the internal classas cannot be extended and unfortunatley they are not marked as 'final' right now. For you that means you need to extend it by a proxy class that reimplements the original class protocol and uses the original class as a property.

Good afternoon!
Could anyone explain what we're supposed to do with internal classes like the mysqli class.
In an article on Zend.com (http://www.zend.com/php5/articles/php5-mysqli.php) the fact that the object oriented interface can be extended is brought as a major feature. But it seems that it's impossible to extend the mysqli class, see my bug at http://bugs.php.net/bug.php?id=28430.
What I want is this. I need some custom logging for my database layer. So I want to extend the mysqli class and overwrite one or two methods and add some custom methods.
Shouldn't I be able to just do:
class foo extends mysqli { }
$foo = new foo();
Right now this doesn't work - the variable $foo->thread_id isn't available for example.
Is this intended behaviour?
