As an experienced PHP developer with no ZF experience, I found frustration with the lack of complete application tutorials available on the Zend Framework website or other web resources.
The problem with any book covering Zend Framework is that new features are released so frequently that it is soon out of date (ZF is currently version 1.10). In my case I wanted a tutorial that covered building a ZF application that used Zend_Application which was released as part of ZF1.8.
Having no experience of ZF, I found this book really helpful, however, it does have many typos and a few errors. Although, I found that none of these things actually meant I mis-understood the point; they were just annoying.
The Apache Ant usage would probably have been suited as late chapter rather than early on. However, it is quite easy to re-write the few lines of code in order to run the examples without Apache Ant.
The chapters covering model data resources, and forms are excellent tutorials in their own right. I would have loved the coverage of functional testing using PHPUnit to have been more in depth.
If you are seeking to learn how to develop Zend Framework applications then this book, although not perfect, is probably the best available right now.
