What do you mean by "one controller to another", exactly?

* Are you using _forward() or the ActionStack, and trying to pass data
from one controller to the next using one of these?
* Or are you talking about passing data between requests?

The answers will be different based on how you answer those questions.

In the case of the first, _forward() accepts an array of parameters to
pass as the fourth argument (_forward($action, $controller, $module,
$params)). ActionStack requires you to either update your request object
and pass it (or create a new one and pass that), or use the
actionToStack() method, which has the same signature as _forward().

In the case of the second, you'll need to pass the data using the
session. Zend_Session_Namespace is quite easy:

// Setting the data:
$namespace = new Zend_Session_Namespace('someaction');
$namespace->data = $arrayOfData;

// Retrieving the data:
$namespace = new Zend_Session_Namespace('someaction');
$data = $namespace->data;
