<?php
// telling ZF where an action helper is
class Bootstrap extends Application\Bootstrap {

    public function _initActionHelpers()
    {
        Zend\Loader\PluginClassLoader::addStaticMap(array('loggedinuser' => 'Planet\Controller\Helper\LoggedInUser'));
    }

    // registering FC plugins can be done like this
    // or simply add resources.frontcontroller.plugins.admin = "PPN\Plugin\AdminContext" to application.ini
    public function _initFcPlugins()
    {
        $this->bootstrap('FrontController');
        $fc = $this->getResource('FrontController');

        $fc->registerPlugin($plugin);
    }

<?php
class IndexController extends Action
{

    public function init()
    {
        // some AHs are pre-aliased, see Zend\Controller\Action\HelperLoader
        $this->fm = $this->broker('flashmessenger');
        // accessing an AH which was aliased in the Bootstrap
        $this->loggedInUser = $this->broker('loggedinuser');
