this repository is communication using protocol tcp with the server using nodejs(net required) and the client using php, before you use this repository i'm recommended to read this article TCP introduction.

• install nodejs
  

• install php5-sockets
  

• install IDE(recomended Netbeans because the repository using netbeans)
  

• run the server that been use nodejs
  

• for the server code
  

    var net = require('net');
    var server = net.createServer(function (socket) {
    // We have a connection - a socket object is assigned to the connection automatically
    console.log('CONNECTED: ' + socket.remoteAddress +':'+ socket.remotePort);
    socket.on('data', function(data) {    
        //var datas = JSON.parse(data); //if you receive json must be parse 
        console.log('DATA ' + socket.remoteAddress + ': ' + data);  
        socket.write("you said: " + data + '\r\n');
        socket.end();
    });
    socket.on('connect', function() {
        console.log("client already connected");
    });
    socket.on('end', function() {
        console.log('DONE');
    });
    });
    server.listen(1338, '127.0.0.1');
    console.log("server is listen on 1338");

save to app.js run with sudo node app.js
or in windows you can use node.exe app.js

• run in terminal with php TCPClient.php
  

    define('__LIB__', dirname(dirname(__FILE__)));
    require_once(__LIB__ . '/php/library/TCPConnection.php');
    require_once(__LIB__ . '/php/library/TCPCallback.php');

    class TCPClient implements TCPCallback {
            public $socket;
        public function index() {
            $this->socket = new TCPConnection("127.0.0.1", 1338, $this);
            $data = array("username" => "foo", "pass" => "bar");
            $this->socket->connect();
            //$socket->send("testing socket TCP dari viyancs"); // format string only
            //$socket->emit("login",  array((object)($data),  (object)($data1))); //multy dimension json
            $this->socket->emit("login", array($data)); //one array dimension json
        }

    public function onConnect() {
        echo "socket is connected 
";
        echo "-------------------------------------------------------------
";
    }

    public function onDisconnect() {
        echo "socket is disconnected 
";
        echo "-------------------------------------------------------------
";
    }

    public function onError($err) {
        echo "something wrong : " .$err;
    }

    public function onJSON($json) {
        echo "receive data from server 
";
        echo "=============================================================
";
        echo "the data is " .$json. '
';
        echo "=============================================================

    }

    public function onJSONEvent($event, $jsonArray) {
        echo "receive data from server 
";
        echo "=============================================================
";
        echo "the event is " .$event. '
';
        foreach ($jsonArray as $key => $value) {
            echo "Key: $key; 
";
            var_dump($value); echo '
';
        }
        echo "=============================================================
";
    }

    public function onMessage($message) {
        echo "message from sever :" .$message;
    }

    public function onSend($msg) {
        echo "sending data to server 
";
        echo "=============================================================
";
        echo 'data = ' .$msg .'
';
        echo "=============================================================
";
    }

    }

    $client = new TCPClient();
    $client->index();

Version 1.0 Release Note;

• send data using string format
• send data using JSONFormat (JSONObject,JSONArray) and dynamical JSON.
• receive data using string format
• receive data using json format

• problem when receive data from server after connected to server
