VC6写的Web service客户端如何连接PHP服务器端

我用PHP5给的样例，可以实现PHP客户端和服务器端的连接。另外还有一个VC写的客户端，可以连接Java写的基于Axis的服务器端。但是现在想要连接VC客户端到PHP服务器端时，老提示“错误的编码格式”。哪位高手能否帮个忙啊？

PHP服务器端

<?php

//server.php

class Calculator

{

    /**

      * 求和

      *

      * @param float $x

      * @param float $y

      * @return float

      */

    public function calculator($x, $y)

     {

         return $x + $y;

     }

}



$server = new SoapServer('./wps.wsdl');

$server->setClass('Calculator');

$server->handle();

?> 

PHP客户端

<?php

//client.php

$soap = new SoapClient('http://localhost/soap/wps.wsdl');

echo $soap->calculator(1.2, 2.5);

?>

用Zend生成的WSDL描述文件

<?xml version='1.0' encoding='UTF-8'?>



<!-- WSDL file generated by Zend Studio. -->

Java服务器端

public class Calculator 

{ 

 public float calculator(float x, float y)

 {

   float sum;

   sum=x+y;

   return sum;

 }
