Zend framework 2 recommended way for error handling

I noticed that the Skeleton Application that Zend provides does not handle error 500. I know that in ZF1 there was an ErrorController that took care of that. I have done some research online, but did not find a clear cut solution for this.

So what is the best way for error handling in ZF2. Would it be on per module basis or some global exception/error handler?

I know that another solution would be to add ini_set('display_errors', true); to my index.php, but I don't really like that solution. It seems that the framework should provide some way for handling errors.

You can handle the exceptions in anyway you want after catching it as the following example in which you are catching the exception globally...:

In the onBootstrap method in your Module.php you can attach a function to execute when an event occurs, the following attach a function to be executed when an error (exception) is raised:

public function onBootstrap(MvcEvent $e)
{
    $application = $e->getApplication();
    $em = $application->getEventManager();
    //handle the dispatch error (exception) 
    $em->attach(\Zend\Mvc\MvcEvent::EVENT_DISPATCH_ERROR, array($this, 'handleError'));
    //handle the view render error (exception) 
    $em->attach(\Zend\Mvc\MvcEvent::EVENT_RENDER_ERROR, array($this, 'handleError'));
}

and then define the function to handle the error in any way you want, the following is an example:

public function handleError(MvcEvent $e)
{
    //get the exception
    $exception = $e->getParam('exception');
    //...handle the exception... maybe log it and redirect to another page, 
    //or send an email that an exception occurred...
}
