在PHP中访问嵌套Javascript对象

正如标题所示，我试图从PHP中访问嵌套的javascript对象属性。

我的对象是这样声明的。

var requestParams = {
        apiKey: appData.apiKey,
        action: "addJob",
        name : name,
        note: note,
        dropoff: dropoffAddress,
        noOfCars: noOfCars,
        carType: carType,
        pickUpDate: pickUpDate,
        pickUpTime: pickUpTime,
        pickUpDateTime: {}
    };

pickUpDateTime(requestParams对象的最后一个属性)属性有一个嵌套对象，我使用for循环动态地添加键值对。

for(var x = 0; x < dateArray.length; x++){
        var dbMoment = moment(dateArray[x] + " " + pickUpTime,appData.displayDateFormat);
        requestParams.pickUpDateTime[x] = dbMoment.format(appData.dbDateFormat);
    }

当我记录对象时，这是我在控制台中看到的内容。到目前为止一切顺利。

{"apiKey":"ba6f4fc3-0f52-11e3-a51d-fefdb24fa1e7","action":"addJob","name":"Dave Manning","note":"","dropoff":"51st street","noOfCars":"1","carType":"saloon","pickUpDate":"11/06/14,13/06/14,15/06/14","pickUpTime":"14:10",******"**pickUpDateTime":{"0":"2014-06-11 14:10:00","1":"2014-06-13 14:10:00"**,**"2":"2014-06-15 14:10:00"}****,"phone":"452345657654745","pickupAddress":"popes quay","pickupLat":51.9013,"pickupLng":-8.47616,"noOfDates":3}

然而，在我把它发送到我的PHP脚本后，我似乎无法访问pickUpDateTime对象。此刻，我正试图使用下面的代码访问它。但这行不通。此外，当我包含这行代码时，函数不会返回任何内容，因此我可以检查$pickUpDateTime的内容。

$pickUpDateTime = json_decode($this->getRequestValue("pickUpDateTime", true));

我可以访问所有其他属性。例如，这可以正常工作。

$noOfDates = $this->getRequestValue("noOfDates", true);

我知道这可能是一个相对容易的修复，但我似乎不能使它工作。

任何帮助都非常感谢。

下面是我执行var_dump($_REQUEST) 时得到的结果

$jsonValue = json_decode($requestParams);
$pickUpDateTime = $jsonValue['pickUpDateTime'];
