当他在php网站上注销facebook应用程序时，如何让用户从facebook注销

Question

I have the following code which runs when user clicks on logout button:

if ($_GET['m'] == 'logout'){
session_destroy();
$facebook->destroySession();
header("Location: /");

}

The user is logged out of facebook app but is still online on Facebook. How to sign out the user from facebook too? Thanks

Answer 1

Use php sdk of facebook and paste below code in your file

    require_once 'facebook/src/facebook.php';
    $facebook = new Facebook (array(
         'appId'  => '*****************',
         'secret' => '****************************'  
));

 $user = $facebook->getUser();
$homeurl = 'index.php';//url you want to redirect after facebook logout


if ($user) 
{
      $logoutUrl = $facebook->getLoginUrl(array('redirect_uri'=>$homeurl));
}
