如何使用PHP中的SoapClient類向XML元素添加其他屬性

Question

我無法弄清楚如何使用php將其他屬性添加到xml文檔。

要從Bing Ads Api請求報告，我需要使用SOAP傳遞信息。我沒有任何SOAP體驗，因此我正在通過Ewan Hemmings示例在這裏工作 - http://www.ewanheming.com/bing-ads-api-campaign-download。我需要做一些微妙的改變，將LastSyncTimeInUTC作爲Null傳遞。

我看過simpleXML擴展，但我更願意繼續使用Bing文檔中使用的SoapClient類。

我一直在搞亂\ SoapVar - http://www.php.net/manual/en/soapvar.soapvar.php，但我不能得到的例子工作。這是我嘗試創建的XML文檔的示例，以及我在下面使用的代碼。我真正想要解釋的唯一一點是如何使用SoapVar將屬性添加到LastSyncTimeInUTC。任何幫助，將不勝感激。

$response = $client->DownloadCampaignsByAccountIds($downloadRequest); 

echo $client->__getLastRequest();

好消息，我計算出如何做到這一點。

我不完全相信它是正確的，但它確實有效。我不太明白它是如何工作的，但這是我所做的。

======= OLD CODE ==================== 
$downloadRequest = array(
"AccountIds" => array(new \SoapVar($accountId, XSD_LONG, 'xsd:long')), 
"DownloadFileType" => "Tsv", 
"Entities" => "Campaigns AdGroups Ads Keywords", 
"PerformanceStatsDateRange" => array("PredefinedTime" => "LastFourWeeks") 
"FormatVersion" => "2.0",); 

======= NEW CODE ==================== 
$downloadRequest = new stdClass(); 
$downloadRequest->AccountIds -> long = new SoapVar($accountId, XSD_LONG, 'xsd:long'); 
$downloadRequest->DownloadFileType = "Csv"; 
$downloadRequest->Entities = "Keywords"; 
$downloadRequest->PerformanceStatsDateRange->PredefinedTime = "LastFourWeeks"; 
$downloadRequest->FormatVersion = "2.0"; 
$downloadRequest->LastSyncTimeInUTC = new SoapVar('<ns1:LastSyncTimeInUTC xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true" />', XSD_ANYXML);
