Retrieving Family information from Facebook using FQL?

Hi I am trying to pull information from Facebook using FQL. I was able to gather info on my friends and the profile users likes however I cant seem to get a list of family information, the code I currently have is below. I was wondering if anyone could help and let me know what I am doing wrong, any help would be great appreciated, thanks

<h1>My Family</h1>
      <?php
              $user    = $facebook->getUser();
              $friends = $facebook->api('/me/friends');

              $fql_query  =   array(
                  'method'    => 'fql.query',
                  'query'     => "SELECT profile_id, name, relationship F开发者_如何学JAVAROM family WHERE profile_id={$user}");
              $family = $facebook->api($fql_query);
              $fam = count($family);
              echo $fam;

              for ($i=0;$i<$fam;$i++){
                echo "<p>".$family[$i]['name']." ".$family[$i]['relationship']." from ".$family[$i]['sex']." </p>";
              }
         ?>

You need friends_relationships extended permission to get access to the user's family.

also "sex" you have there seems unrelated

You need user_relationships permission to view the user's family info.
