在这里先介绍标准的webservice。
那么如何创建wsdl呢？对于PHP来说这确实是件很不容易的事情，有人说用zend studio创建很方便，这是一种方法。但对于那些不喜欢用zend studio的人来说，会觉得创建一个web service还要安装zend studio，太强人所难了。
在这里介绍一个简单的方法，到网上下载SoapDiscovery.class.php类，里面有个公用方法：getWSDL，这个方法末尾是用的return，那么，你修改一下这个方法：
//return sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '</definitions>');
//生成wsdl文件，将上面的return注释
$fso = fopen($this->class_name . ".wsdl" , "w");
fwrite($fso, sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '</definitions>'));
现在生成wsdl的类有了，SoapDiscovery.class.php（源码在最末尾）。

再准备一个提供服务的Service.php类文件或者函数就可以创建wsdl了!

public function HelloWorld() {

return "Hello";

public function Add($a, $b) {

return $a + $b;

} ?>

　　创建wsdl文件的creat_wsdl.php

include("Service.php");

include("SoapDiscovery.class.php");

$disco = new SoapDiscovery('Service', 'soap'); //第一个参数是类名（生成的wsdl文件就是以它来命名的），即Service类，第二个参数是服务的名字（这个可以随便写）。

$disco->getWSDL();

　　运行create_wsdl.php文件，此时会生成一个Service.wsdl的文件

　　再在Service.php文件中添加一些代码

public function HelloWorld() {

return "Hello";

public function Add($a, $b) {

return $a + $b;

$server = new SoapServer('Service.wsdl', array('soap_version' => SOAP_1_2));

$server->setClass("Service"); //注册Service类的所有方法

$server->handle(); //处理请求

?>

　　创建webservice客户端程序，测试webservice是否有效，文件名是：client.php
将以下内容拷贝进去：


     Add(28, 2);   echo $soap->__soapCall('Add',array(28,2))//或这样调用

　　OK！测试通过！

二、无WSDL文件方式

　　服务器端

<?php

class Service

{

public

function HelloWorld()

{

return "Hello";

}

public

function Add(

$a,

$b)

{

return

$a+

$b;

}

$server=

new SoapServer(

null,

array('uri' => "abcd"));

$server->setClass("Service");

$server->handle();

　　　客户端

<?php

try {

$soap =

new SoapClient(

null,

array(

"location" => "http://localhost/Dragon/soap/Service.php",

"uri" => "abcd",

资源描述符服务器和客户端必须对应

"style" => SOAP_RPC,

"use" => SOAP_ENCODED

));

echo

$soap->Add(12, 2);

}

catch (Exction

$e) {

echo

print_r(

$e->getMessage(),

true);

}

三．出现的问题。

1.在方法中对属性的赋值在其他方法中不起作用。
比如在客户端调用服务端某个方法对某个属性赋值。
在其他方法里就不能用。但在 __construct 方法中对属性的赋值是可以个在其他方法中使用的。

2. 提示 Client] looks like we got no XML document错误。
服务器端文件在<?php ?> 标签前后都不要有任何数据包括空格，空行。

3. Warning: SoapClient::SoapClient(): I/O warning : failed to load external entity
原因如下：PHP程序作为 SOAP客户端采用 WSDL 模式访问远端服务器的时候，PHP是通过调用 libcurl 实现的。至少在 PHP5.2.X 是这样的。如果采用 non-WSDL 模式，就不需要 libcurl。除了了ibcurl以外，至少还关联的库包括：libidn,ibgcc,libiconv,libintl,openssl

现在，你已经解决你了系统接口的问题了！剩下的空余时间，就有必要去了解什么是SOAP、http协议、XML了！
