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 

创建一个文件composer.json，然后填入如下语句，

{

    "require": {

        "dnode/dnode": "0.2.0"

    }

}

执行如下语句安装，

$ 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);

三、利用php创建客户端程序client.php, 其中需要引用刚才安装的dnode文件夹里面的文件autoload.php

<?php

// Connect to DNode server running in port 7070 and call 

// Zing with argument 33

require 'lib/vendor/autoload.php';



// This is the class we're exposing to DNode

class 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
