企业级应用，主要是讲PHP5对webservice的一些实现(以下的程序可以被JAVA，NET，C等正常调用)
国内用PHP写WebService的真的很少，网上资料也没多少，公司的项目开发过程中，经历了不少这方面的东西，写出来以供大家参考（谢谢老农提供的WSDL和程序文件）
客户端

代码:
01.<?php
02.header ( "Content-Type: text/html; charset=utf-8" );
03./*
04.* 指定WebService路径并初始化一个WebService客户端
05.*/
06.$ws = "http://soap/soapCspMessage.php?wsdl";
07.$client = new SoapClient ( $ws, array ('trace' => 1, 'uri' => 'http://www.zxsv.com/SoapDiscovery/' ) );
08./*
09.* 获取SoapClient对象引用的服务所提供的所有方法
10.*/
11.echo ("SOAP服务器提供的开放函数:");
12.echo ('<pre>');
13.var_dump ( $client->__getFunctions () );
14.echo ('</pre>');
15.echo ("SOAP服务器提供的Type:");
16.echo ('<pre>');
17.var_dump ( $client->__getTypes () );
18.echo ('</pre>');
19.echo ("执行GetGUIDNode的结果:");
20.//$users = $client->GetUsers();
21.//var_dump($HelloWorld );
22.$parameters = array('uname'=>'zxsv',"upassword"=>'123');
23.$out = $client->HelloWorld($parameters);
24.$datadb = $out->HelloWorldResponse;
25.var_dump($out);
26.?>

服务端

代码:

01.<?php
02.class Member
03.{
04.public $UserId;
05.public $Name;
06.public function __construct($parmas){
07.$this->UserId = $parmas[0];
08.$this->Name = $parmas[1];
09.}
10.}
11.$servidorSoap = new SoapServer('testphp.xml',array('uri' => 'http://www.TestPHP.com/','encoding'=>'utf-8','soap_version' => SOAP_1_2 ));
12.$servidorSoap->setClass(Testphp);
13.$servidorSoap->handle();
14.class Testphp {
15.public function HelloWorld($uid){
16.return array('HelloWorldResult'=>"mystring".$uid->{'uname'}.' and '.$uid->{'upassword'});
17.}
18.public function GetMember($uid){
19.$s=array();
20.for($i=0;$i<$uid->{'uid'};$i++){
21.$s[] =&amp;new Member(array($i, $uid->{'uname'}.'我测试'.$i));
22.}
23.return   array('GetMemberResult'=>$s);
24.}
25.}
26.?>

到这里应该都看的懂吧

这里有返回的两个字段，一个是返回字符串，这个很好理解

01.<s:element name="HelloWorld">
02.<s:complexType>
03.<s:sequence>
04.<s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" />
05.<s:element minOccurs="0" maxOccurs="1" name="upassword" type="s:string" />
06.</s:sequence>
07.</s:complexType>
08.</s:element>
09.<s:element name="HelloWorldResponse">
10.<s:complexType>
11.<s:sequence>
12.<s:element minOccurs="0" maxOccurs="1" name="HelloWorldResult" type="s:string" />
13.</s:sequence>
14.</s:complexType>
15.</s:element>

这一段就字符串的
那返回数组的就比较麻烦了，我和老农搞了一两周才发现是WSDL文件写错了，看下面的一段

01.<s:element name="GetMember">
02.<s:complexType>
03.<s:sequence>
04.<s:element minOccurs="1" maxOccurs="1" name="uid" type="s:int" />
05.<s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" />
06.</s:sequence>
07.</s:complexType>
08.</s:element>
09.<s:element name="GetMemberResponse">
10.<s:complexType>
11.<s:sequence>
12.<s:element minOccurs="0" maxOccurs="1" name="GetMemberResult" type="tns:ArrayOfMember" />
13.</s:sequence>
14.</s:complexType>
15.</s:element>
16.<s:complexType name="ArrayOfMember">
17.<s:sequence>
18.<s:element minOccurs="0" maxOccurs="unbounded" name="Member" nillable="true" type="tns:Member" />
19.</s:sequence>
20.</s:complexType>
21.<s:complexType name="Member">
22.<s:sequence>
23.<s:element minOccurs="1" maxOccurs="1" name="UserId" type="s:int" />
24.<s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" />
25.</s:sequence>
26.</s:complexType>

第一段GetMember是输入，最重要的是GetMemberResponse这段，看type=”tns:ArrayOfMember”这里，返回一 个数组，WSDL中定义了ArrayOf这个，后面的就简单了，ArrayOfMember的类型是type=”tns:Member” ，从name=”Member”得到要返回的数组，完工。

Ping Service，博客程序提供一种通知机制,以便在第一时间将博客的更新信息发布到提供Ping Service服务的网站，写聚合的时候研究了一下
先看标准吧
这是一个标准的Ping Service,用XMLRPC来传数据的，注释写的这么详细，代码说明就不需要了吧，PHP5开启XMLRPC方法
client.php

代码:
01.<?php
02.$host  = 'zxsv';
03.$port  = 80;
04.$rpc_server = '/test/xmlrpc_server.php';
05.$title = 'zxsv';
06.$server = 'http://zxsv/test/';
07.$rss = 'http://zxsv/test/rss.php';
08.//weblogUpdates.Ping方法
09.$Ping = xmlrpc_encode_request('weblogUpdates.Ping', array($title, $server ));
10.//weblogUpdates.extendedPing方法
11.$extendedPing = xmlrpc_encode_request('weblogUpdates.extendedPing', array($title, $server, $rss ));
12.//调用rpc_client_call函数把所有请求发送给XML-RPC服务器端后获取信息
13.$response = rpc_client_call($host, $port, $rpc_server, $Ping);
14.$split = '<?xml version="1.0" encoding="iso-8859-1"?>';
15.$xml =  explode($split, $response);
16.$xml = $split . array_pop($xml);
17.$response = xmlrpc_decode($xml);
18.//输出从RPC服务器端获取的信息
19.print_r($response);
20./**

26.* $request  封装的XML请求信息

41.  
return $contents;
42.}
43.?>

server.php

代码:

WebService的最常用的两种方法算是写齐了
