Database Abstraction

Hello!

I have a question: Do you have any intention to include a feature like
database abstraction layer at PHP4? I was thinking to use PHPLib to do
this, but I have found some things at their code that I didn't like...

Of course that I can write functions or classes just to do that but if we
have something implemented directly in PHP4 it will be easier and the most
important thing: it's difficult to implement something really generic that
can be used with all databases. I think that we need specialists at many
DBMS to do the right thing and to have good performance at all of
them. I've worked a lot with Oracle but I didn't know the other DBMS
suficiently to do a really good work. The databases are the heart of a
site and if you loose performance doing dumby functions, it can be
critical...

If there is an interest in implementing that, I would like to colaborate.

Thanks,
Andre.
