soap的简单实现(PHP)

1.非wsdl模式

(1)函数文件

testphp/ServiceFunctions.class.php

<?php
 
/**
 * @author 左小兵
 *
 */
class ServiceFunctions  {
 
    public    function getDisplayName($f,$l) {
        $name='';
        $name.=$f;
        $name.=$l;
        return $name;
    }
    public function countWords($c){
        return count($c);
    }
}
 
?>

(2)服务端文件

testphp/soapserver.php

<?php
require_once 'ServiceFunctions.class.php';
$options=array('uri'=>'http://localhost');
$server=new SoapServer(null,$options);
$server->setClass("ServiceFunctions");
$server->handle();
?>

(3)客户端文件

testphp/SoapClient.php

<?php
    $options=array(
    'uri'=>'http://localhost',
    'location'=>'http://localhost/testphp/soapserver.php',
    'trace'=>1
    );
    $client=new SoapClient(null,$options);
    echo $client->getDisplayName('joec','bloggs');
?>

2.wsdl模式

函数文件和服务端文件一样

(1)新加入一个生成wsdl文件的php类,并且要先访问这个类,以生成wsdl文件.

testphp/SoapDiscovery.class.php
