    $request = new FacebookRequest($session, 'GET', '/me'); 
    $response = $request->execute(); 
    // get response 
    $graphObject = $response->getGraphObject(); 
    $fbid = $graphObject->getProperty('id');    
    $name = $graphObject->getProperty('name'); 
    $email = $graphObject->getProperty('email'); 

    /////////////////////////////////////// 

$request1 = new FacebookRequest($session, 'GET', '/me/invitable_friends?fields=id,name,picture.type(normal)&limit=5'); 
$response1 = $request1->execute(); 

$graphObject1 = $response1->getGraphObject(); 
$fname = $graphObject1->AsArray(); 


} else { 
$permissions = ['email', 'user_friends']; 
    $loginUrl = $helper->getLoginUrl($permissions); 
header("Location: ".$loginUrl); 
} 
?>

上述响应我得到如何获得单独的变量每个配置文件照片。

答

PHP的stdClass是标准对象，您可以访问它的属性作为公共属性。我建议阅读有关如何handle objects properties的PHP文档。

来自Facebook的响应是与对象的数组内，并用于表示一个人的每个对象有图片属性内的另一个对象，以例如访问第一用户的第一图像：

$response[0]->picture->data->url

'$ friendpic = $ graphObject1 [0] - > picture-> data-> url; '不起作用。 – user7364693
