Inisialisasi Composer
composer init

Menambah Autoloading

 * composer.json

Menambahkan Namespace
Karena setiap class yang ada di dalam direktori utama ada dalam namespace app, maka kita akan menambahkan namespace app\core untuk setiap class yang ada di dalam direktori core.


 * core/Application.php


 * core/Router.php

Update Composer
Untuk mengaktifkan autoloading, kita perlu meng-update composer. composer update

Setelah selesai, maka di dalam direktori vendor akan ada file autoload.php. vendor/ ├── autoload.php └── composer

Menyertakan Autoload
Pada index.php, tambahkan  untuk menyertakan autoload. Kemudian, tambahkan  untuk menggunakan class Application.


 * index.php
