Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

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).

	<?php

	Route::group(['prefix' => '{lang}'], function () {
	// ...
	});

	<?php
	Localizater::group(function () {
	Route::view('/', 'welcome');
	Route::get('/foo', 'Controller@action');
	});

	Route::delete('foo', 'Controller@action');
	Route::post('login', 'Controller@action');

	// Result of locales are (en, fr)
