$helperPath = '/path/to/custom/helpers'; Zend_Controller_Action_HelperBroker::addPath($helperPath);
$helperPath = Zend_Controller_Front::getInstance()->getModuleDirectory('moduleName') . '/library/MyPackage/Controller/Action/Helper'; Zend_Controller_Action_HelperBroker::addPath($helperPath);In this example, we add a package library as a helper path. This is useful when using third-party libraries that provide their own set of action helpers. By adding the package library as a helper path, the action helpers provided by that library can be easily accessed and used in controllers. Package library: Zend Framework.
