php call .net web service?该如何解决

php call .net web service???
Hello,every body:

I have a question about PHP call .net webservice, please help me.
Why the server can not access the array value i sent?
===================================================================
Here is the SOAP 1.1 request and respond example
------------------------------------------------
POST /DMService.asmx HTTP/1.1
Host: sboserver1
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/InsertTest"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
  <InsertTest xmlns="http://tempuri.org/">
  <s>
  <string>string</string>
  <string>string</string>
  </s>
  </InsertTest>
  </soap:Body>
</soap:Envelope>
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
  <InsertTestResponse xmlns="http://tempuri.org/">
  <InsertTestResult>
  <string>string</string>
  <string>string</string>
  </InsertTestResult>
  </InsertTestResponse>
  </soap:Body>
</soap:Envelope>

======================================================
Here is the method that client code call the method 'InsertTest':
----------------------------------------------------
<?php
$soap = new soapclient($wsdl,'wsdl');  
$soap->soap_defencoding = 'UTF-8';
$soap->decode_utf8 = false;
$soap->xml_encoding = 'UTF-8';
$result = $soap->call('InsertTest',array('s' => array('0000','aaaa')),'', '', false, true,'document','encoded');
var_dump($result);

?>
Why the server can not access the array value i sent?
======================================================

Are you Chinese?
If you are Chinese, please refer to http://blog.csdn.net/mynamesucks/archive/2006/05/26/756480.aspx
Otherwise, see following.
replace
$result = $soap-> call('InsertTest',array('s' => array('0000','aaaa')),'', '', false, true,'document','encoded');
to
$proxy = $soap->getProxy();
$result = $proxy-> InsertTest(array('s' => array('0000','aaaa')),'', '', false, true,'document','encoded');

.NET的WS有若干种编码方式，其中有一种是和PHP不兼容的。我忘记了具体是Encoded还是Literal。不过已经有人用NuSoap解决了这个问题。具体代码如果你要，我大概还是能找到的。
