     column names in the query */
  ufollower.id AS follower_id,
  ufollower.username AS follower_name,
  ufollowed.id AS followed_id,
  ufollowed.username AS followed_name

  JOIN users ufollower ON ufollower.id = user_follow.follower

   echo '<a href="'.$apple['followed_id'].'">+'.htmlspecialchars($apple['followed_name']) .'</a> ';
