I would have agreed a few years back, but these days the amount of PHP code I write relative to the project size is small enough that there's no ROI to switch platforms, even for new projects. Most of the code I write is static javascript, and PHP exists only to load and save the business data. That's also why all of those frameworks aren't very relevant to me. I have no use for server-side MVC because the server isn't involved in the application UI. I have no use for ORM, because building up an object structure in memory only to deflate it again into a web service response is often overkill. I do use Zend Framework, but I use it to simplify my transactional DB logic and to assist in bootstrapping the web services.
