$storage = new \OAuth\Common\Storage\Memory();
// Create the access token from the strings you acquired before.
$token = new \OAuth\OAuth1\Token\StdOAuth1Token();
$token->setAccessToken($accessToken);
$token->setAccessTokenSecret($accessTokenSecret);
// Add the token to the storage.
$storage->storeAccessToken('Flickr', $token);
