The new PHP Zend Framework is out (v0.1.1). There's really lot of classes inside to digest; many to-be-standardized algorhitms inside; all in all an interesting read. However, unless all these PHP classes get precompiled into PHP, it's hard to see a reason to include 881kb (~/library/*) of on-the-fly compiled PHP code into every php app. The feed parser, pdf generator and search demos look great though. The ActiveRecord implementation; the Zend_db_DataObject sounds very promising; I'll have a more indepth look over the next weeks.
