在PHP中如何创建和使用webservice？

写个最简单的例子就行， 在写个调用公共webservice的例子， 感谢！！！！！

php webservice实例(简单易懂)
首先大家要简单了解了何谓webservice，接下来就做两个非常简单的例子，webservice还是逃不开server端与client端。
我测试的环境为：apache2.2.11 php5.2.10
做这个测试之前，要确认你的php配置文件中已经将soap扩展打开，即extension=php_soap.dll;
OK 现在我们来体验webservice
//server端 serverSoap.php
$soap = new SoapServer(null,array('uri'=>" http://192.168.1.179/"));//This uri is your SERVER ip.
$soap->addFunction('minus_func');    //Register the function
$soap->addFunction(SOAP_FUNCTIONS_ALL);
$soap->handle();
function minus_func($i, $j){
    $res = $i - $j;
    return $res;
}
//client端 clientSoap.php
try {
    $client = new SoapClient(null,
array('location' =>" http://192.168.1.179/test/serverSoap.php",'uri' => " http://127.0.0.1/")
    );
    echo $client->minus_func(100,99);
} catch (SoapFault $fault){
    echo "Error: ",$fault->faultcode,", string: ",$fault->faultstring;
}
这是客户端调用服务器端函数的例子，我们再搞个class的。
//server端 serverSoap.php
$classExample = array();
$soap = new SoapServer(null,array('uri'=>" http://192.168.1.179/",'classExample'=>$classExample));
$soap->setClass('chesterClass');
$soap->handle();
class chesterClass {
    public $name = 'Chester';
    function getName() {
    return $this->name;
    }
}
//client端 clientSoap.php
try {
    $client = new SoapClient(null,
array('location' =>" http://192.168.1.179/test/serverSoap.php",'uri' => " http://127.0.0.1/")
    );
    echo $client->getName();
} catch (SoapFault $fault){
    echo "Error: ",$fault->faultcode,", string: ",$fault->faultstring;
}
妈了个巴子的以上代码我已经测试通过
