php - 如何使用 PHP 中的 SoapClient 类向 XML 元素添加附加属性

Question

我无法弄清楚如何使用 php 将附加属性添加到 xml 文档。

要从 Bing Ads Api 请求报告，我需要使用 SOAP 传递信息。我没有任何 SOAP 经验，因此我正在使用 Ewan Hemmings 示例 - http://www.ewanheming.com/bing-ads-api-campaign-download 。我需要进行一些细微的更改，将 LastSyncTimeInUTC 作为 Null 传递。

我已经研究过 simpleXML 扩展，但我更愿意继续使用 Bing 文档中使用的 SoapClient 类。

我一直在摆弄\SoapVar - http://www.php.net/manual/en/soapvar.soapvar.php但我无法让这些例子发挥作用。这是我尝试创建的 XML 文档的示例，以及我在下面使用的代码。我真正想解释的唯一一点是如何使用 SoapVar 向 LastSyncTimeInUTC 添加属性。任何帮助将不胜感激。

Answer 1

好消息，我知道怎么做了。

我并不完全相信它是正确的，但它确实有效。我还不太明白它是如何工作的，但这就是我所做的。

======= 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);
