Introduction

The Laravel service container is a powerful tool for managing class dependencies and performing dependency injection. Dependency injection is a fancy phrase that essentially means this: class dependencies are "injected" into the class via the constructor or, in some cases, "setter" methods.

Let's look at a simple example:

 1<?php
 2 
 3namespace App\Http\Controllers;
 4 
 5use App\Http\Controllers\Controller;
 6use App\Repositories\UserRepository;
 7use App\Models\User;
 8 
 9class UserController extends Controller
10{
11    /**
12     * The user repository implementation.
13     *
14     * @var UserRepository
15     */
16    protected $users;
17 
18    /**
19     * Create a new controller instance.
20     *
21     * @param  UserRepository
