Use Dnode to implement a simple example of communication between PHP and Nodejs _node.js

I. Installation of Dnode

1, for Nodejs, performing

Copy Code code as follows:

$ sudo npm install Dnode

2, for PHP, using composer to install Dnode PHP

Execute the following statement to download the composer

Copy Code code as follows:

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

Create a file Composer.json, and then fill in the following statement,

Copy Code code as follows:

{
"Require": {
"Dnode/dnode": "0.2.0"
}
}

Perform the following statement installation,

Copy Code code as follows:

$ sudo php composer.phar install

Second, the use of Nodejs to create a simple server program, Server.js

Copy Code code as follows:

var Dnode = require (' Dnode ');
var Server = Dnode ({
Zing:function (n, CB) {CB (n * 100)}
});
Server.listen (7070);

third, the use of PHP to create a client program client.php, which need to refer to the Dnode folder just installed file autoload.php

Copy Code code as follows:

<?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 so provides us all methods
From the server
$remote->zing (function ($n) use ($connection) {
echo "n = {$n}\n";
Once we have the result we can close the connection
$connection->end ();
});
});
$loop->run ();
?>

Four, the implementation of server-side

Copy Code code as follows:

$ node Server.js

v. Execute client-side Invoke server program

Copy Code code as follows:

$ PHP client.php

This invokes the server-side addition program, and then outputs the result

Copy Code code as follows:

n = 3300
