I am learning phprpc Remote Call, follow the online tutorial, found the error: Incorrect response ID (Request ID:1, Response ID:) n; good tangle, ask for advice. The post code is as follows:

require_once ' jsonrpcserver.php ';
/**

time:11:06
*/ 
class member
{ 
Public function GetName ()
{return ' hello word ';//return string}

} 
//Service-side call
$myExample = new Member ();
//Injection Instance
Jsonrpcserver::handle ($myExample) or print ' no request ';
Client: client.php
<?php
/**
