About

This project can be used to aid in dependency injection in your own projects. The implementation, which is PSR-11 container compliant, is as bare-bones as can be without compromising on functionality. It is capable of resolving concrete implementations for classes, interfaces, and bindings, and primitives, as well as invoking closures, functions, and bound methods with their dependencies.

Requirements

Installation

Composer

composer require elverion/dependency-injection

Usage

It is as simple as obtaining the instance of the container object and making use of the ->make() or ->resolve() methods (to obtain a concrete implementation of some abstract) or use ->call() to call a method and inject dependencies into it. For example:

<?php

use Elverion\DependencyInjection\Container\Container;

class MyApp {
    private $client;

    public function __construct(Client $client) {
        $this->client = $client;
    }

    // ...
}

class Task {
    public function handle(MyApp $app) {
        // ...
    }
}



$container = Container::getInstance();

$task = new Task();
$container->call([$task, 'handle']); // Injects a Client into MyApp, then calls Task::handle() with the MyApp instance
