如何在返回单个值的同时将Object数组转换为数组

如何在返回单个值的同时将Object数组转换为数组，这是我得到的o/p，当我只得到一家酒店时，我如何将其转换为代码中显示的第0[0]值。当我在o/p找到一家酒店时，我在访问时遇到了问题。print_r($result); via foreach()

    stdClass Object
    (
        [cityId] => 000000000020
        [checkInDate] => 2013-12-20
        [checkOutDate] => 2013-12-21
        [customerId] => 
        [customerAccountType] => SH01
        [customerType] => 
        [currency] => INR
        [noOfRoomsRequested] => 1
        [searchAvailabilityResult] => stdClass Object
            (
                [hotelId] => IXW1
                [hotelName] => Ginger Jamshedpur
            )
   )
