一，安装DNode，
1， for nodejs， 执行
$ sudo npm install dnode
2, for php, 利用composer来安装DNode php
执行下列语句下载composer
$ wget http://getcomposer.org/composer.phar
{ "require": { "dnode/dnode": "0.2.0" }}$ sudo php composer.phar install
二，利用nodejs创建简单server程序， server.js
var dnode = require('dnode');var server = dnode({ zing: function (n, cb) { cb(n * 100) }});server.listen(7070);<?php // Connect to DNode server running in port 7070 and call // Zing with argument 33require 'lib/vendor/autoload.php';// This is the class we're exposing to DNodeclass Temp{ // Compute the client's temperature and stuff that value into the callback public function temperature($cb) { }}$loop = new React\EventLoop\StreamSelectLoop();$dnode = new DNode\DNode($loop, new Temp());$dnode->connect(7070, function($remote, $connection) { // Remote is a proxy object that provides us all methods // from the server $remote->zing(33, function($n) use ($connection) { echo "n = {$n}\n"; // Once we have the result we can close the connection $connection->end(); });});$loop->run();?>四，执行服务器端
$ node server.js
五，执行客户端调用服务端程序
$ php client.php
这会调用服务器端的加法程序，然后输出结果
n = 3300
