Chapter 2. The Request and Response Life Cycle

This chapter is a quick look at Symfony's fundamental features. We will use the request/response life cycle as a tool to discuss Model-View-Controller (MVC) in general and explore Symfony concepts such as routing, action (or controller, if you like), TWIG, Doctrine, and application setup. We will have a look at bundles and see how all of these concepts are organized in a bundle. Apart from creating a new bundle in this chapter, we will discuss the installation and how to modify and use bundles created by other developers.
