The Zend Framework
The Zend Framework was released a few days ago. This is a PHP5-only web application framework from Zend, “the PHP company.” It has been in development for a long time, but if that had a chilling effect on the development of other PHP frameworks, it’s hard to see.
I’m going to go straight for my grim conclusion here: I think many of the other PHP web frameworks in development have no long-term prayer against Zend. It’s not about technical merits, it’s about the business case that Zend is a safer bet than five random guys with a Trac install and a cool logo.
