命名空间对象选择列表php - Namespaced object to select list php

Namespaced object to select list php

我正在尝试使用联邦快递api https://github.com/101medialab/shipping在我的网站。我不擅长php，当我尝试代码:

$calculator = new MediaLab'Shipping'Calculator'FedExCalculator($key,$password, $accountNumber, $meterNumber); $calculator->calculate($source, $destination, $shipment);

我可以看到它的响应如下:


    Array
    (
        [0] => MediaLab'Shipping'Model'Estimation Object
            (
                [carrier:MediaLab'Shipping'Model'Estimation:private] => FedEx
                [serviceName:MediaLab'Shipping'Model'Estimation:private] => First overnight
                [serviceCode:MediaLab'Shipping'Model'Estimation:private] => FIRST_OVERNIGHT
                [deliveryDate:MediaLab'Shipping'Model'Estimation:private] => DateTime Object
                    (
                        [date] => 2015-07-27 08:00:00
                        [timezone_type] => 3
                        [timezone] => Europe/Paris
                    )
                [cost:MediaLab'Shipping'Model'Estimation:private] => MediaLab'Shipping'Model'Cost Object
                    (
                        [currency:MediaLab'Shipping'Model'Cost:private] => USD
                        [amount:MediaLab'Shipping'Model'Cost:private] => 161.59
                    )
            )
        [1] => MediaLab'Shipping'Model'Estimation Object
            (
                [carrier:MediaLab'Shipping'Model'Estimation:private] => FedEx
                [serviceName:MediaLab'Shipping'Model'Estimation:private] => Priority overnight
                [serviceCode:MediaLab'Shipping'Model'Estimation:private] => PRIORITY_OVERNIGHT
                [deliveryDate:MediaLab'Shipping'Model'Estimation:private] => DateTime Object
                    (
                        [date] => 2015-07-27 10:30:00
                        [timezone_type] => 3
                        [timezone] => Europe/Paris
                    )
                [cost:MediaLab'Shipping'Model'Estimation:private] => MediaLab'Shipping'Model'Cost Object
                    (
                        [currency:MediaLab'Shipping'Model'Cost:private] => USD
                        [amount:MediaLab'Shipping'Model'Cost:private] => 71.65
                    )
            )
    )

但是我很困惑，我如何才能得到这些值显示在一个选择列表

下面应该构建一个选择框来显示结果:

$calculator = new MediaLab'Shipping'Calculator'FedExCalculator($key,$password, $accountNumber, $meterNumber);
$results = $calculator->calculate($source, $destination, $shipment);
var $html = '<select>';
foreach ($results as $result) {
    $cost = $result->getCost()->getCurrency() . $result->getCost()->getAmount();
    $html .= '<option name="' . $result->getServiceCode() . '">' . $result->getCarrier() . ' - ' . $result->getServiceName() . ' - ' . $result->getDeliveryDate() . ' - ' . $cost . '</option>';
}
$html = '</select>';
echo $html;

基本上，循环遍历结果并使用对象提供的方法来获取所需的数据。在https://github.com/101medialab/shipping/blob/master/src/MediaLab/Shipping/Model/EstimationInterface.php查看所有可用方法的类接口可能会有所帮助。
