How to copy access_token from address?

Question

In contact with

I use VKontakte authorization by sending the user to this address

oauth.vk.com/authorize?client_id=<?=$client_id;?>&display=page&redirect_uri=https://oauth.vk.com/blank.html&scope=<?=$scope;?>&response_type=token&v=5.37

After authorization, the contact will redirect to the following address:

oauth.vk.com/blank.html#access_token=0000000000&expires_in=0&user_id=111111

How can I get the access_token from here in the controller?

Answer 1

$params = array(
        'client_id' => $client_id,
        'client_secret' => $client_secret,
        'code' => $_GET['code'],
        'redirect_uri' => $redirect_uri
    );

$token = json_decode(file_get_contents('https://oauth.vk.com/access_token' . '?' . urldecode(http_build_query($params))), true);

$token['access_token']
