Facebook how to get a friends_hometown?

I am using FB graph v3 and i already 开发者_如何学编程ask for permission to friends data. But when i try to get access it won't return any value for hometown

my permission array 'scope' => 'offline_access,publish_stream,user_birthday,user_location,user_about_me,user_hometown, friends_hometown, friends_location'

if ($user){ //get user basic description $userInfo = $facebook->api("/$user"); //print_r($userInfo); try{

        $friends =  $facebook->api("/$user/friends");
    //  echo $friends->('friends_hometown');
        print_r($friends->data);


    }

Returned is: Array ( [0] => stdClass Object ( [name] => Jim Wel [id] => 100001572804563 ) )

How can i get friends_hometown friends_location???

regards

Not sure exactly how the Facebook SDK works since I wrote my own, but id it returns the JSON properly this should work:

 $friends = $facebook->api('/me/friends');
 for($i = 0; $i < count($friends); $i++){
      $friend = $facebook->api('/'.$friends[$i]->id);
      echo $friend->hometown->name.'<br />';
 }

Remember to request permissions "friends_hometown" too.
