                if(mysqli_query($mysqli, "INSERT INTO cars(car_plate_no, car_company_name, car_name, car_model, car_color, car_fuel_type, car_owner_name, car_description) VALUES ('$carPlate','$carCompany','$carName','$carModel','$carColor','$carFuelType','$carOwnerName','$carDescription')" )){

                  }

              }

              ?>

错误说明：
分析错误：语法错误，在第33行的C:\xampp\htdocs\meccaniko\work\profile\add-car.php中出现意外的“”（t_boolean_or）
这段代码怎么了，上面写着这是出乎意料的
