5. The topic ofthistalk
is kind ofalie...“Laravels IoC container”

6. Thetruth...
The Laravelapplication
isan IoC container
class Application extends Container [...] {
[...]
}

7. Dependencyinjection
comes first

8. App::make('foo');

9. Instantiation
App::bind('foo', function()
{
return new FooBar;
});
$foo = App::make('foo'); // instance of FooBar
Or resolvethe class directly
$foo = App::make('FooBar'); // same as 'new FooBar';

10. Singleton objects
App::singleton('bar', function()
{
return new BarFoo;
});
$foo = App::make('bar'); // instance of BarFoo

11. Swapoutbinded objects
$foo = new Foo;
App::instance('foo', $foo);
» Great for testing

12. Internal
dependencies

13. Taylor magic™

14. Automatic dependencyresolving
class OrderController extends BaseController {
protected $orders;
public function __construct(OrderRepository $orders)
{
$this->orders = $orders;
}
public function getIndex()
{
$all = $this->orders->all();
return View::make('orders', compact('all'));
}
}

15. Instead of
$orderRepository = new OrderRepository;
$orderController = new OrderController($orderRepository);
We use
$orderController = App::make('OrderController');
Couldalso beachievedthisway
$orderRepository = new OrderRepository;
$orderController = App::make('OrderController', [$orderRepository]);

16. More awesome stuff
* Service providers
* Interface binding
