I've been studying Zend Framework a lot lately as our company is moving to using that more. I think I own or have read every book on the subject and have read some tutorials. The best book I've found to get started is 'Beginning Zend Framework' by Armando Padilla. (no, I'm not Armando and have no affiliation with him).
I haven't really found a tutorial worth getting started with. I haven't figured out why but Zend Framework seems to be something that teachers have hard time teaching.
