PHP中soap的用法实例
本文实例讲述了PHP中soap的用法，分享给大家供大家参考。具体用法分析如下：
PHP使用soap有两种方式。
一、用wsdl文件
服务器端：
<?php
classservice
{
publicfunctionHelloWorld()
{
return "Hello";
}
public functionAdd($a,$b)
{
return$a+$b;
}
}
$server=newSoapServer('soap.wsdl',array('soap_version'=>SOAP_1_2));
$server->setClass("service");
$server->handle();
?>资源描述文件，可以用工具(zendstudio)生成。其实就是一个xml文件。
<?xmlversion="1.0"encoding="UTF-8"?>
