Answer 1

See the add View Variable section below

add it in your module.php file.

You can also do this using view helper.

/**
     * Remember to keep the init() method as lightweight as possible
     * 
     * @param \Zend\ModuleManager\ModuleManager $moduleManager
     */
    public function init(ModuleManager $moduleManager) 
    {        
        $events = $moduleManager->getEventManager();
        $events->attach('loadModules.post', array($this, 'modulesLoaded'));
        $events->attach('onBootstrap', array($this, 'bootstrap'));

        $sharedEvents = $events->getSharedManager();
        $sharedEvents->attach(__NAMESPACE__, 'bootstrap', array($this, 'bootstrap'), 100);
        $sharedEvents->attach(__NAMESPACE__, 'bootstrap', array($this, 'initializeView'), 100);
        $sharedEvents->attach(__NAMESPACE__, 'dispatch', array($this, 'addViewVariables'), 201);        
    }


/**
 * 
 * @param \Zend\Mvc\MvcEvent $e
 */
public function loadConfiguration(MvcEvent $e) 
{        
    $e->getApplication()->getServiceManager()
            ->get('ControllerPluginManager')->get('AclPlugin')
            ->checkAcl($e); //Auth/src/Auth/Controller/AclPlugin      
}

/**
 * 
 * @param \Zend\EventManager\EventInterface $e
 */
public function bootstrap(Event $e) {

    $eventManager = $e->getParam('application')->getEventManager();
    //$app->getEventManager()->attach('dispatch', array($this, 'checkAcl'), 100);
}

/**
 * pass variables to layout
 * 
 * @param \Zend\EventManager\EventInterface $e
 */
public function addViewVariables(Event $e) 
{
    $route = $e->getRouteMatch();
    $viewModel = $e->getViewModel();
    $variables = $viewModel->getVariables();
    if (false === isset($variables['controller'])) {
        $viewModel->setVariable('controller', $route->getParam('controller'));
    }
    if (false === isset($variables['action'])) {
        $viewModel->setVariable('action', $route->getParam('action'));
    }

    $viewModel->setVariable('module', strtolower(__NAMESPACE__));        
}

/**
 * 
 * @param \Zend\Mvc\MvcEvent $e
 */
public function initializeView(Event $e) 
{

}

and in your layout you can simply access those variables using their name such as $module, $action, $controller according to above example
