Ich versuche derzeit, eine Single Sign On-Seite zu erstellen, auf der sich der Benutzer nach der Anmeldung entweder über Facebook oder Google+ auf die Providerseite umleitet und nach erfolgreicher Anmeldung wieder zur index.php umleitet Seite? ˅. Nun ist das Problem, ich möchte wissen, gibt es Möglichkeiten, um zu überprüfen, ob der Benutzer angemeldet ist. Beispiel, sobald sich der Benutzer anmeldet, sollte sich die Login-Schaltfläche in Logout ändern. Kann ich das wissen? Danke im Voraus.PHP SSO Sitzung prüfen

Das ist mein login.php Code:

// token URL processing and some popular Pro/Enterprise examples. The code below
// assumes you have the CURL HTTP fetching library with SSL.
require('helpers.php');
ob_start();
// PATH_TO_API_KEY_FILE should contain a path to a plain text file containing
// only your API key. This file should exist in a path that can be read by your
// web server, but not publicly accessible to the Internet.
$janrain_api_key = trim(file_get_contents('apiKey.txt'));
// Set this to true if your application is Pro or Enterprise.
$social_login_pro = false;
// Step 1: Extract token POST parameter
$token = $_POST['token'];
if ($token) {
// Step 2: Use the token to make the auth_info API call.

'token' => $token,

// Step 3: Parse the JSON auth_info response
$auth_info = json_decode($result, true);
if ($auth_info['stat'] == 'ok') {
echo "\n auth_info:";
echo "\n"; var_dump($auth_info);
// Pro and Enterprise API examples

include('social_login_pro_examples.php');
}
