Just tested the second framework for php. The first was Smarty and the second was is Symfony.
The first one was rather harder to use and you had to do a lot of work by hand and was very buggy.
The second one is rather good comparing to the first.It offers MVC architecture and support for developing an application with this profile.
On the developers site is a very good tutorial which constructs a new fully functional site from scratch in 21 days.
Just reached the 8th day and until now , everything works like clock-work.
Maybe you should try it!
