Silex

http://silex.sensiolabs.org

● PHP micro framework.● Based in Symfony2 components.● Very extensible.● Very modular.● Big responsibility.

Silex

● Define a controller and map to a route:

require_once __DIR__.'/../vendor/autoload.php';$app = new Silex\Application();

$app->get('/blog/{id}', function ($id) { return 'blog item'.$id;});

$app->get('/userportal', 'userPortal.controller:indexAction');

$app->get('/main/admin', function ($id) { return 'Legacy code here';});

$app->run();
