PHP中SOAP到XML的转换

我需要使用SOAP生成以下XML：

                    ...
                <InternationalShippingServiceOption>
                        <ShippingService>StandardInternational</ShippingService>
                        <ShippingServiceCost currencyID="USD">39.99</ShippingServiceCost>
                        <ShippingServicePriority>1</ShippingServicePriority>
                        <ShipToLocation>CA</ShipToLocation>
                    </InternationalShippingServiceOption>
                    ...

除了我没有在XML中的ShippingServiceCost标记中生成currencyID=USD属性之外，一切都很好。我该怎么做？

为什么，我很高兴你问我。我今天刚解决了这个问题

$shippingsvccostwithid = new SoapVar(array('currencyID' => $whatever),SOAP_ENC_OBJECT, 'ShippingServiceCost', 'https://your.namespace.here.com/');
$params = array("InternationalShippingServiceOption" => array(
    "ShippingService" => "StandardInternational",
    "ShippingServiceCost" => $shippingsvccostwithid,
    "ShippingServicePriority" => 1,
    "ShipToLocation" => "CA"
);

然后像往常一样继续

如果您需要更多帮助，请告诉我。

您不需要使用SoapVar。这至少对我有用：

$params =   array(
         'InternationalShippingServiceOption' => array(
            'ShippingService'=>'StandardInternational',
            'ShippingServiceCost' => array('_' => 39.99, 'currencyID' => 'USD')
            'ShippingServicePriority'=>1,
            'ShipToLocation'=>'CA',
        )
    )

我将此技术用于PayPal SOAP API。

没有直接思考，添加了更多信息。如果您不介意的话，我有一个关于PayPal SOAP API的问题。如何设置“版本”？当我设置它时，标记变成“xsd:string”而不是“Version”。更多信息，谢谢！

$params =   array(
         'InternationalShippingServiceOption' => array(
            'ShippingService'=>'StandardInternational',
            'ShippingServiceCost' => array('_' => 39.99, 'currencyID' => 'USD')
            'ShippingServicePriority'=>1,
            'ShipToLocation'=>'CA',
        )
    )
