PHP - SOAP请求 - nest XML作为param

Question

我需要使我的XML肥皂的结构看起来如下：

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.fines.pl/api/contract">
    <SOAP-ENV:Body>
        <ns1:newApplicationRequest>
            <user_login>XYZ</user_login>
            <user_password>XYZ</user_password>
            <contract>
<?xml version="1.0" encoding="UTF-8"?>

我已经将$params变量设置为包含具有各自值的user_login和user_password元素，但是我不知道如何将此contract参数设置为使用必需的内容。

使用XML代码提供$contract变量(我认为可能是解决方法(便便Fatal error: Uncaught SoapFault exception: [xml_structure] String could not be parsed as XML错误。

将感谢解释如何完成。

您已经两次声明了<?xml?>，第一行在第一行中，第二行是八个。那是我在XML方面看到的唯一错误。
