Redirect when authorizing VK API?

Question

PHP

Hello everybody.
I am making a standalone application on VK API. How can I redirect to my site (for example, to the site.ru/auth.php page), after the user has allowed access to the application? Although I know how to make a redirect, but how to accept a token - alas :(
Tell me?
