其中有个web method像这样的：

 
[WebMethod] 
public string HelloWorld() 
{ 
return "Hello World"; 
} 

ok，一切就绪。在某php文件中如下写法：
php5本身就支持SOAP调用Web Service:

 
<?php 
//get localization strings from C# webservice 
$client = new SoapClient('http://localhost/webservice1/Localization.asmx?wsdl'); 

echo "Call web service method from C# WebService:\n"; 
$result = $client->GetLocalizationResource(); 

if(!is_soap_fault($result)) 
{ 
echo "return:\n", $result->GetLocalizationResourceResult; 
} 
else 
{ 
echo "soap call fault"; 
} 
?> 

这样就OK了，会继续介绍SOAP
