State of PHP and Architecture

What is the state of the art of PHP Architecture? Our CTO, Johann-Peter Hartmann, wants to know about it. Furthermore we want to know about the relevance of business goals during architecture creation. It would be great if you could help us filling out this survey, of course we’ll publish it later. Please answer questions based on real-world experience and not what you would like to see. :-)

The survey can be found here.
