Laravel's Dependency Injection Container in Depth

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).

Accessing the Container

<?php

use Swagger\Annotations as SWG;

/**
 * @SWG\Swagger(
 * 		basePath="/v1",
 * 		host="api.local",
 * 		schemes={"http"},
 * 		produces={"application/json"},

appkr

<?php
/**
 * @example
 * 
 * $a = new ProcessExecutor();
 * $b = function ($arg){ sleep(1);echo "hello $arg\n"; };
 * $a->setRunnables($b,['aaa','bbb']);
 * $a->setCheckStatus(function($arg){return $arg === 'aaa';});
 * $a->execute();
 * var_dump($a->getRunStatusArr());

If you have two days to learn the very basics of modelling, Domain-Driven Design, CQRS and Event Sourcing, here's what you should do:

In the evenings read the [Domain-Driven Design Quickly Minibook]{http://www.infoq.com/minibooks/domain-driven-design-quickly}. During the day watch following great videos (in this order):

1. Eric Evans' [What I've learned about DDD since the book]{http://www.infoq.com/presentations/ddd-eric-evans}
2. Eric Evans' [Strategic Design - Responsibility Traps]{http://www.infoq.com/presentations/design-strategic-eric-evans}
3. Udi Dahan's [Avoid a Failed SOA: Business & Autonomous Components to the Rescue]{http://www.infoq.com/presentations/SOA-Business-Autonomous-Components}
