DEPENDENCY INJECTION class Foo { public function bar() { $coffee = new Coffee(); $coffee->init(); return $coffee->drink(); } }

Slide 9

Slide 9 text

DEPENDENCY INJECTION $coffee = new Coffee();

SERVICE LAYER OR: HOW SYMFONY IS ONLY IMPLEMENTATION

Slide 17

Slide 17 text

SERVICE LAYER > Seperation of concerns > Business logic should not be bound to the application > Service layer can be accessed through the service container

Slide 18

Slide 18 text

SERVICE LAYER public function showAction($productId) { $product = $this->getDoctrine() ->getRepository('AppBundle:Product') ->find($productId); if (!$product) { throw $this->createNotFoundException( 'No product found for id '.$productId ); } // ... do something, like pass the $product object into a template }
