How I Zend stormed.

Dear habrareyudi. In the first lines of my letter, I want to say thank you to the habra people who wrote the Introduction to the Zend Framework and the Introduction to the Zend Framework (continued) . Thanks to these articles, I finally made my old dream and began slowly but surely learning HIM. But before rushing into battle, I would like to ask a few questions and get advice from people who have been in Zend for a long time, so as not to go the wrong way from the very beginning.


1. The question is the first and most philosophical. Should I use third-party template engines, in my case it is Smarty, or does it make sense to work only with Zend_View?

2. Reading the documentation, I came across Zend_Form, which, in my opinion, provides a very convenient mechanism for working with forms. But! But is it convenient to use it in practice, and what is the mechanism for the design of the form transferred from the controller to the view? It has been shown to me that it is still more convenient to use simple HTML forms from a design point of view. If this is not the case, tell me what is wrong.

3. If someone has the opportunity to give a look at the sources, where even a simple user authentication mechanism is grammatically implemented, I will be infinitely grateful.


Thank you all for any opinions expressed.
