Surfing along zend.com I found a nice advertisement banner of them, which gives an impression on which large companies are using PHP (since they use a Zend product, I guess they do).

The problem is, they don't say what part of their enterprise uses it. For instance, Altavista uses PHP, but only for their music search part, that's pretty sizable. And we all know about Yahoo! But Apple using PHP? I can't see PHP in any of their front facing pages (corp site, apple store, support site, dotMac), mostly all I see is a whole bunch of WebObjects.
Link to commentI think Zend needs more "case studies" which show how specific Zend solutions solved problems in the enterprise of these big companies.

I fully agree here. But in this case I recently had a request of a company which mainly does Java and wanted to know if "PHP is ready for the enterprise". They were pretty impressed by the list! ;)

I'm waiting for an English version of this new book. It may be able to answer the most burning question I have about design patterns in PHP.
Link to commentI've seen dozens of PHP design patterns, but all of their violate the first principle of design patterns—program to an interface and not an implementation.
How is that possible with a non-typed language like PHP? I'd be interested in any source that has an answer to that question.
