A simple example of using DNode to implement communication between php and nodejs_node.js

1. Install DNode

1, for nodejs, execute

Copy code The code is as follows:

$ sudo npm install dnode

2, for php, use composer to install DNode php

Execute the following statement to download composer

Copy code The code is as follows:

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

Create a file composer.json and fill in the following statements,

Copy code The code is as follows:

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

Execute the following statement to install,

Copy code The code is as follows:

$ sudo php composer.phar install

2. Use nodejs to create a simple server program, server.js

Copy code The code is as follows:

var dnode = require('dnode');
var server = dnode({
zing: function (n, cb) { cb(n * 100) }
});
server.listen(7070);

3. Use PHP to create the client program client.php, which needs to reference the file autoload.php in the dnode folder you just installed

Copy code The code is as follows:

// 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 ReactEventLoopStreamSelectLoop();
$dnode = new DNodeDNode($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();
?>

4. Execute server side

Copy code The code is as follows:

$ node server.js

5. Execute the client to call the server program

Copy code The code is as follows:

$ php client.php

This calls the server-side addition routine and prints the result

Copy code The code is as follows:

n = 3300
