$helperBroker = Zend_Controller_Action_HelperBroker::getStaticHelperBroker(); $helperBroker->addPrefix('My_Helper');
$helperBroker = Zend_Controller_Action_HelperBroker::getStaticHelperBroker(); $helperBroker->addPrefix('My_Helper', 'My_Module');This code adds the prefix 'My_Helper' to the names of all action helpers that are registered with the helper broker, but only for the 'My_Module' module. In both examples, the addPrefix() method is being used to modify the behavior of the action helper broker by adding a prefix to the names of the helpers. The package library used in these examples is Zend_Controller_Action_HelperBroker.
