// retrieve the 'flashMessenger' action helper $flashMessenger = Zend_Controller_Action_HelperBroker::getExistingHelper('flashMessenger');
// retrieve the 'layout' action helper $layout = Zend_Controller_Action_HelperBroker::getExistingHelper('layout'); // set the layout script to use for this action $layout->setLayout('mylayout');In this example, we're retrieving the 'layout' action helper and then setting the layout script to use for the current action to 'mylayout'. This can be useful when you have multiple layout scripts that you want to use for different sections of your application. Overall, Zend_Controller_Action_HelperBroker is a package library that provides a useful set of tools for working with action helpers in a Zend Framework project. The getExistingHelper method is just one of the many methods available that can help simplify your code and make it easier to manage your helpers.
