phprpc远程调用报错,不知道什么原因

我在学习phprpc远程调用,按照网上的教程,发现报错:Incorrect response id (request id: 1, response id: ) n;好纠结啊,求教。贴出代码如下:
服务端,member.php
<?php
require_once 'jsonRPCServer.php';
/**

  • User: Administrator
  • Date: 2015/12/28
  • Time: 11:06
    */
    class member
    {
    public function getName()
    {

            return 'hello word '; // 返回字符串
    }
    

}
// 服务端调用
$myExample = new member();
// 注入实例
jsonRPCServer::handle($myExample) or print 'no request';

客户端:client.php
<?php
/**

  • User: Administrator
  • Date: 2015/12/28
  • Time: 11:07 */ require_once 'jsonRPCClient.php'; //$url = 'http://localhost/phprpc/server.php'; $url = 'http://localhost/phprpc/member.php'; $myExample = new jsonRPCClient($url); echo '
    '; print_r($myExample); // 客户端调用

try
{
$name = $myExample->getName();
echo $name;
} catch (Exception $e)
{
echo nl2br($e->getMessage()) . '
' . "n";
}
