[![Build Status](https://camo.githubusercontent.com/801bb1384792379944439d6b1d24dbfbb5c3499ee9b6ea6c386ba7d33254ac3d/68747470733a2f2f7472617669732d63692e6f72672f4d69646e6967687444657369676e2f6175746f6d617469632d64692e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/MidnightDesign/automatic-di)

This package provides automatic dependency injection for PHP. It requires a [container-interop](https://github.com/container-interop/container-interop)-compatible container.

Installation
------------

[](#installation)

Composer: [midnight/automatic-di](https://packagist.org/packages/midnight/automatic-di)

Usage
-----

[](#usage)

Let's say we have the following interfaces and classes:

```
interface FooInterface {
}

class Foo {
    private $bar;
    public function __construct(Bar $bar) {
        $this->bar = $bar;
    }
}

class Bar {
}

interface BazInterface {
}

class Baz {
}

class Hodor {
    private $baz;
    public function __construct(BazInterface $baz) {
        $this->baz = $baz;
    }
}
```

Now we can use the `AutomaticDiContainer` like this:

```
$wrappedContainer = new Some\Other\Container; // An implementation of Interop\Container\ContainerInterface
$config = Midnight\AutomaticDi\AutomaticDiConfig::fromArray([
    'preferences' => [
        FooInterface::class => Foo::class,
    ],
    'classes' => [
        Hodor::class => [
            'baz' => Baz::class,
        ],
    ],
]);
$container = new Midnight\AutomaticDi\AutomaticDiContainer($wrappedContainer, $config);

$foo = $container->get(FooInterface::class); // Returns an instance of Foo
$hodor = $container->get(Hodor::class); // Returns an instance of Hodor with an injected Baz
```

Performance

> This package works via reflection. Isn't that slow?

Yes, it is. A cache is coming soon.
