如何从中获取$ album->的数据？

I am getting album information by above scripts. How can I get the data of $album->from?

    $response = file_get_contents($token_url);
    if($response=='')   {   echo "<script>window.location='index.php'</script>";    }

     $params = null;
     parse_str($response, $params);

     $graph_url_albums = "https://graph.facebook.com/10150293277371173?access_token=" 
       . $params['access_token'];
     $albums = json_decode(file_get_contents($graph_url_albums));
     }     

    ("token " . $params['access_token']);
    echo $albums_id=$albums->id; echo "</br>";

Well according to the Facebook API the Album object has access to the following fields:

> id from name description location link cover_photo privacy count type
> created_time updated_time

So what happens when you do:

echo $albums->from;
