Based in Symfony2 components.

Very extensible.

Very modular.

Big responsibility.

14. Silex
●
Define a controller and map to a route:
require_once __DIR__.'/../vendor/autoload.php';
$app = new SilexApplication();
$app->get('/blog/{id}', function ($id) {
return 'blog item'.$id;
});
$app->get('/userportal', 'userPortal.controller:indexAction');
$app->get('/main/admin', function ($id) {
return 'Legacy code here';
});
$app->run();
