Stefan Mischook has posted a video podcast looking at the Zend Framework and Web 2.0 development:

I just released a new PHP video podcast where I answer a few questions put to me about php. I answer these questions: Do you need to learn the Zend Framework?, Do you need a PHP certificate?, How does PHP fit into Web 2.0.

You can view the podcast here or check out some of his other great videos in the Video section of his site.
