Get your object-oriented skills sharp by exploring the ideas and reasons behind dependency injection. This simple principle separates developers who write functional code from those that are able to build great, and maintanable applications. In this tutorial, we'll see dependency injection in action, why it's important, and how it relates to services and service-oriented architecture. We'll also refactor our application to use a dependency injection container, using a fantastic - but simple - container called Pimple.
If you're ready to take your object-oriented code to the next level, AND actually be excited about doing it, this tutorial is for you!
