How to choose the right PHP Framework?

[iris2027]

Hi!

I'm a PHP Pro, but haven't use any PHP framework till now, so I have no clue on
how to choose a PHP Framework . Do you have some tips to help me choose the/a right PHP Framework?

I want a stable and secure PHP framework for Projects with about 400 hours development time.
It should be possible to use the framework on Shared-Hosting-Webservers.
I don't need some AJAX support (I'm using extJS).
It would be nice if the framework supports Rapid Application Development
and object-relational mapping.

Also some of the standard-functions (Authentification, form validation) would
be nice. Caching would be a usefull, but isn't needed.

Needs for a PHP framework:
- Shared-Hosting-Webserver-Support
- for Projects between 200 und 400 hours work
- Developing Modell "Rapid Application Development" supported
- object-relational mapping supported
If possible:
- Caching
- Already finished Modules (e.g. Authentification, form validation, ..)
- Easy to learn


Which PHP framework is the right one I am seeking for?

thx

I actually never used any PHP framework, I think it's more usefull to do everything by myself. However I read some articles about PHP frameworks and I'm sure the best one is Zend framework; The only problem is that it doesn't support AJAX, but you don't need it, so it's perfect for you.
