How to make user signed out from facebook when he logs out of facebook application on a php website

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

}

用户退出facebook应用程序，但facebook仍在线。如何从facebook注销用户?由于

使用facebook的php sdk并将下面的代码粘贴到您的文件

    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));
}
