Laravel's Dependency Injection Container in Depth

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

Accessing the Container
