Answer 1

PHPsdk 5 and v2.8

$fb = new Facebook\Facebook([
  'app_id'                => 'xxxxxxxxx',
  'app_secret'            => 'xxxxxxxxxxxxxxxxxxxxxxxxxxx',
  'default_graph_version' => 'v2.8',
]);

$helper = $fb->getRedirectLoginHelper();
try {

  $accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // There was an error communicating with Graph
  echo $e->getMessage();
  exit;
}

$client = $fb->getOAuth2Client();
try {
  // Returns a long-lived access token
  $accessTokenLong = $client->getLongLivedAccessToken($accessToken);
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // There was an error communicating with Graph
  echo $e->getMessage();
  exit;
}

if (isset($accessTokenLong)) {
  // Logged in.
  $_SESSION['facebook_access_token'] = (string) $accessTokenLong;
}
