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

$diffIds = \Illuminate\Support\Str::of($inputStrIds = '1,2,5, ')
    ->trim()->trim(',')->trim()
    ->explode(',')
    ->filter(function ($value){
        return filled($value);
    })
    ->map(function ($item){
        return trim($item);

        $this->queue[] = [$item, $priority];
        $this->sort();
