使用DNode实现php和nodejs之间通信的简单实例

$ sudo npm install dnode

$ wget http://getcomposer.org/composer.phar

{
    "require": {
        "dnode/dnode": "0.2.0"
    }
}

$ sudo php composer.phar install

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 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();
?>

$ node server.js

$ php client.php

n = 3300
