League\Di

The League\Di library provides a fast and powerful Dependency Injection Container for your application.

Install

Via Composer

{
    "require": {
        "league/di": "1.*"
    }
}

Usage

Get a Container Object

include 'vendor/autoload.php';

$container = new League\Di\Container;

Bind a concrete class to an interface

$container->bind('\Foo\Bar\BazInterface', '\Foo\Bar\Baz');

Automatic Dependency Resolution

The Di Container is able to recursively resolve objects and their dependencies by inspecting the type hints on an object's constructor.

namespace Foo\Bar;

class Baz
{
  public function __construct(Qux $qux, Corge $corge)
  {
    $this->qux = $qux;
    $this->corge = $corge;
  }

  public function setQuux(Quux $quux)
  {
    $this->quux = $quux;
  }
}

$container->resolve('\Foo\Bar\Baz');

Defining Arguments

Alternatively, you can specify what to inject into the class upon instantiation.

Define Constructor Args

$container->bind('\Foo\Bar\Baz')->addArgs(array('\Foo\Bar\Quux', '\Foo\Bar\Corge'));

$container->resolve('\Foo\Bar\Baz');

Define Methods to Call with Args

$container->bind('\Foo\Bar\Baz')->withMethod('setQuux', array('\Foo\Bar\Quux'));

$container->resolve('\Foo\Bar\Baz');
