Returning the value of a variable from controller to form or

hello everybody Actually i am new to zend framework. I know that i can return a value of a variable from a form to the controller. Can I also return a value from the controller to any form or any model? If this is possible then please tell me that how can we do it.

Thanks in advance.

I thought zend was a php framework, in some sense a competitor of Rails. I did not know you could do Rails in the zend framework.
