Events are the new hooks. But what is an event really? How can you best describe an event in your code? What types of events are there, and how do you decide whether or not to implement something as an event?

In this talk we take a look at how events are essential to processing a Request and producing a Response. We take a look at the Symfony EventDispatcher and related classes that you need when you want to hook into this process. When you know all about the event system and how you can implement your own events, we discuss some situations which may or may not be good use cases for events. You will learn to decide if using events is the right solution for your problem.
