Facebook Token Problem

[anosim]

When i use: $token = $facebookService->getStorage()->retrieveAccessToken('Facebook');

Error: Call to a member function getStorage() on a non-object

if i use this method: $token = $fb->requestAccessToken( $code );

it is returned Protected Array, i want to Token String to save my Database

Any Solution for Token as String form for save Database

Thanks

try with the below statement. It will fetch the accesstoken string for you.

 $accessToken=$token->getAccessToken();

Just making sure I have this right... We should be using:

$fb->getStorage()->retrieveAccessToken('Facebook')->getAccessToken();
