SoapClient Php无法发送xml数据

我正在使用一个web服务获取XML格式的用户数据，然后将其重新发送到第二个web服务，并进行更改。问题是，每次我发送请求时，我都会创建一个没有数据的新用户。这意味着接受前3个元素，但不接受用户对象。我尝试使用xml和aarray作为输入，但没有任何效果。SaveUser服务需要一个复杂的对象，其WSDL需求如下所示

<s:element name="SaveUser">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Username" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Password" type="s:string"/>
<s:element minOccurs="1" maxOccurs="1" name="CompanyID" type="s:long"/>
<s:element minOccurs="0" maxOccurs="1" name="User" type="tns:User"/>
</s:sequence>
</s:complexType>
</s:element>

谢谢你的帮助
