If you use a dependency container and a Closure instance as the route callback, the closure’s state is bound to the Container instance. This means you will have access to the DI container instance inside of the Closure via the $this keyword:
$app->get('/hello/{name}', function ($request, $response, array $args) {
// Use app HTTP cookie service
$this->get('cookies')->set('name', [
'value' => $args['name'],
'expires' => '7 days'
]);
})
