接触PHP已经多年，可是对webService一直不太了解，最近公司要做要用PHP做一个接口，是在考虑用webService还是直接用HTTP请求，所以这两天也看了不少有关webService方面的资料

下面是一个小实例

action.php文件内容

<?php  
//action.php  
Class Action {  
          /**  
           * Enter description here...  
           *  
           * @param int $num1  
           * @param int $num2  
           * @return int  
            */ 
          public function total($num1,$num2){  
                     return $num1 + $num2;  
          }  
}  
?>  

service.php文件内容

<?php 
//service.php  
require './action.php';  
$server = new SoapServer('./action.wsdl');  
$server->setClass('Action');  
$server->handle();  
?> 

action.wsdl文件内容

<?xml version='1.0' encoding='UTF-8'?> 
<!-- WSDL file generated by Zend Studio. --> 
<definitions name="action" targetNamespace="urn:action" xmlns:typens="urn:action" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" 
    xmlns="http://schemas.xmlsoap.org/wsdl/"> 
    <message name="total"> 
        <part name="num1" type="xsd:integer"/> 
        <part name="num2" type="xsd:integer"/> 
    </message> 
    <message name="totalResponse"> 
        <part name="totalReturn" type="xsd:integer"/> 
    </message> 
 
    <portType name="ActionPortType"> 
        <operation name="total"> 
            <documentation> 
                Enter description here...  
            </documentation> 
            <input message="typens:total"/> 
            <output message="typens:totalResponse"/> 
        </operation> 
    </portType> 
    <binding name="ActionBinding" type="typens:ActionPortType"> 
        <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> 
        <operation name="total"> 
            <soap:operation soapAction="urn:ActionAction"/> 
            <input> 
                <soap:body namespace="urn:action" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> 
            </input> 
            <output> 
                <soap:body namespace="urn:action" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> 
            </output> 
        </operation> 
    </binding> 
    <service name="actionService"> 
        <port name="ActionPort" binding="typens:ActionBinding"> 
            <soap:address location="http://127.0.0.1/bbs/soap2/service.php"/>  <!--  访问service的路径 --> 
        </port> 
    </service> 
</definitions> 

index.php文件内容

<?php  
//index.php  
$test= new SoapClient("http://127.0.0.1/soap2/action.wsdl");  
$result = $test->total(22,1);  
echo $result;  
?>  

其中index.php为调用接口的文件，service.php为接口的服务文件，运行index.php就可以直接得到接口返回的值
