Thanks in advance.

Here is the code that produced this data:

PHP Code:
      public function getUser($uid){
        $this->db->where('user_id', $uid);
        $query = $this->db->get('users');
        return $query->result_array();
      }

      public function getFriendSuggestions() {
        $userId = $this->session->userdata('user_id');
        $friends = $this->getFriends($userId);
        $suggestedFriends = [];
        
        foreach ($friends as $friendId) {
          # Friends friends list.
          $ff_list = $this->getFriends($friendId);
          
          foreach ($ff_list as $ffriendId) {
            # If the friendsFriend(ff) is not us, and not our friend, he can be suggested
            if ($ffriendId != $userId && !in_array($ffriendId, $friends)) {
              
              # The key is the suggested friend
              $suggestedFriends[$ffriendId] = ['mutual_friends' => []];
              $ff_friends = $this->getFriends($ffriendId);
              
              foreach ($ff_friends as $ff_friendId) {
                if (in_array($ff_friendId, $friends)) {
                  # If he is a friend of the current user, he is a mutual friend
                  $suggestedFriends[$ffriendId]['mutual_friends'][] = $ff_friendId;
                }
              }
              
            }
          }
          
        }
        
        # Convert the friend id's to user objects.
        $suggestedFriendObjs = array();
        if (!empty($suggestedFriends)) {
          foreach ($suggestedFriends as $suggestedFriend => $mutualFriends) {

            $suggestedFriendObj = new stdClass();
            $suggestedFriendObj->suggestedUser = $this->getUser($suggestedFriend);
            
            if (!empty($mutualFriends)) {
              $mutualFriendObjs = [];
              foreach ($mutualFriends['mutual_friends'] as $mutualFriend) {
                $mutualFriendObjs[] =  $this->getUser($mutualFriend);
              }
            }
            
            $suggestedFriendObj->mutualFriends = $mutualFriendObjs;
            $suggestedFriendObjs[] = $suggestedFriendObj;
          }
        }
        
        return $suggestedFriendObjs;
      }

    }
