Zend has created a new type of ZF Certification . Appropriately, you can get an electronic version of the book on which the training course takes place here . As for the book on PHP certification, in my opinion it is quite interesting for review. Things that are not so often raised in the numerous literature on a given programming language are considered. I hope that the new training course will also set out not ordinary tips on working with Zend Framework.
The book contains a description of the coding standard used in the framework and all the main objects. I do not know what is the significant difference from the manual, but I think they are. Oh yes, at the end of each chapter, you can test your knowledge by answering test questions.
However, for me more important is the question of obtaining this certificate. Why it may be needed and what advantages it gives. I know that in Russia very few people have certificates from Zend in PHP. Accordingly, the popularity of this new training in our country remains a big question. Although certainly more active promotion of this framework can not but rejoice.
