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

for ($i = 1; $i <= 100; $i++)
{
    if($i % 3 == 0 && $i % 5 ==0){
        echo "FizzBuzz<br />";
    }
    else if($i % 3 == 0){
        echo "Fizz<br />";
    }
    else if($i % 5 == 0){
        echo "Buzz<br />";

<?php

class Collection implements IteratorAggregate
{
    /**
     * The collection contents.
     *
     * @var array
     */
    protected $items;

<?php
require_once "vendor/autoload.php";

use Symfony\Component\Console\Application;
use Illuminate\Database\Console\Migrations;
use Pimple\Container;

$container = new Container();

$container['migration-table'] = 'migration';
