php调用自身一定要用 return

 public function get_quyu_info($data)    {//        $uid=$data[‘uid‘];//        if(!affair("role.Role")->isSuperManager($uid)){//            return $this->ErrorInf("抱歉，您无权操作！");//        }//        ChromePhp::log(1);        if($data[‘pid‘]){            $flag = $this->getorg($data[‘pid‘]);            if ($flag[0][‘flag‘] !=201){                return $this->get_quyu_info($flag[0]);            }        }        else{//            $uid =$data[‘uid‘];            $uid = ‘2250741873492991‘;            $_model = $this->Model("user.User");            $pm = [                ‘condition‘ => "where uid = ‘$uid‘"            ];            $org_code = $_model -> search($pm);            $org_name = $org_code[0][‘atorg‘];            $flag=$this->getorg($org_name);            if($flag[0][‘flag‘] !=201){                return $this->get_quyu_info($flag[0]);            }        }        return $flag;    }
