A bundle is like a plugin… except Symfony2 itself is made up of bundles

What makes a page?

/hello/world

A Route/hello/{name}

A ControllerA PHP function

A Response“<h1>Hello World!</h1>”

Step 1: Create a route

/hello/world

File: app/config/routing.yml

* Routing can also be defined with XML, PHP and as annotations

AcmeDemoBundle:LoneStar:hello maps to

Acme\DemoBundle\Controller\LoneStar::helloAction()

Step 2: Create a controller

/hello/world

File: src/Acme/DemoBundle/Controller/LoneStarController.php

* At its simplest, a controller is just a function

Step 2: Create a controller

/hello/world

File: src/Acme/DemoBundle/Controller/LoneStarController.php

File: app/config/routing.yml

/hello/world

http://yourhost/LoneStarPHP/web/app_dev.php/hello/world

Great… But HTML in controllers? &@*$%!

Meet Twig
