I could get Facebook token from Android device and post the value to the web server.
When I used Facebook PHP SDK, it was easy to get facebook user information.
// Get User ID
$fb_id = $this->facebook->getUser();
// Get User Info
$user_profile = $this->facebook->api('/me');
Just this one line gave me all the information.
I have no idea how to get a user information by using only facebook token that I get from mobile.
// get mobile token
$fb_token = $this->input->post('fb_token');
$user_info = 'https://graph.facebook.com/me?access_token='.$fb_token;
Ok. so It looks like I get joson data if I use above url address.
How can I bring the array data into the server?
After the user has authenticated (SSO) you can simply use the Facebook object to make requests:
You can make synced requests: API Requests or asynced: Async API Requests
