Let's not just use Symfony, let's conquer it! In this series, you and I will journey to the center of Symfony by ripping open the source code, adding debug statements and seeing what really happens between the request and the response. It's as geeky-awesome as it sounds.
Besides dinosaurs, expect to do the following on our adventure:
- Create an event listener that does amazing things
- Step through the HttpKernel::handle() method that's used in Symfony and Drupal 8
- See where event like kernel.request, kernel.response and others are dispatched
- Learn about request attributes and the magic they give us
- Find out what is a sub-request and how to handle it
- Create your own sub-request manually
