Answer» Laravel service container is a great and POWERFUL tool to manage dependencies and to perform dependency INJECTION. So now the question comes what is dependency injection - In classes dependencies will be injected through either constructor or setter method. <?php namespace App\Http\Controllers; use App\Employee; use App\Repositories\EmployeeRepository; use App\Http\Controllers\Controller; class EmployeeController extends Controller { /** * The employee repository implementation. * * @var EmployeeRepository / protected $employees; /* * Create a new controller instance. * * @param EmployeeRepository $employees * @RETURN void / public function __construct(EmployeeRepository $employees) { $this->employees = $employees; } /* * Show the profile for the given employee. * * @param int $id * @return Response */ public function show($id) { $employee = $this->employees->find($id); return view('employee.profile', ['employee' => $employee]); } } Here EmployeeController NEEDS to retrieve INFORMATION of employee from a data source so we have injected a service that will provide information of the employee.

<?php namespace App\Http\Controllers; use App\Employee; use App\Repositories\EmployeeRepository; use App\Http\Controllers\Controller; class EmployeeController extends Controller { /** * The employee repository implementation. * * @var EmployeeRepository */ protected $employees; /** * Create a new controller instance. * * @param EmployeeRepository $employees * @RETURN void */ public function __construct(EmployeeRepository $employees) { $this->employees = $employees; } /** * Show the profile for the given employee. * * @param int $id * @return Response */ public function show($id) { $employee = $this->employees->find($id); return view('employee.profile', ['employee' => $employee]); } }

Here EmployeeController NEEDS to retrieve INFORMATION of employee from a data source so we have injected a service that will provide information of the employee.
