Description Author

This package provides example code to interact with a server using a WebSockets client.

It provides classes and example scripts to create interactive applications using Web sockets.

Currently, it provides an example that uses the Ratchet library to handle events of a WebSocket connection when a client connects, when a message is sent, or when a client connection is closed.

Socket Programming Using PHP

Here bin folder is contain server file that you can execute on command.
Src folder is contain atual logic on it.
First, Download Ratchet Library file on your pc using composer

composer require cboden/ratchet

Then after Create Our Login File on src folder ( RealTimeData.php )

namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class RealTimeData implements MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = new \SplObjectStorage;
        //print_r($this->clients);
    }

    public function onOpen(ConnectionInterface $conn) {
        // Store the new connection to send messages to later
        $this->clients->attach($conn);

       // print_r($conn->resourceId);

        echo "RealTime Data New connection! ({$conn->resourceId})\n";
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        $numRecv = count($this->clients) - 1;
        //echo sprintf('Connection %d sending message "%s" to %d other connection%s' . "\n"  , $from->resourceId, $msg, $numRecv, $numRecv == 1 ? '' : 's');
        
        $msg = json_decode($msg);
       //print_r($msg);
        foreach ($this->clients as $client) {
            if ($from === $client) {
                // The sender is not the receiver, send to each client connected
                $client->send(json_encode(array('status'=>"Success")));
            }
        }
    }

    public function onClose(ConnectionInterface $conn) {
        // The connection is closed, remove it, as we can no longer send it messages
        $this->clients->detach($conn);

        echo "Connection {$conn->resourceId} has disconnected\n";
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";

        $conn->close();
    }
}

After done this thing create server on bin folder ( realtimedata.php )

<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\RealTimeData;

    require dirname(__DIR__) . '/vendor/autoload.php';

    $server = IoServer::factory(
        new HttpServer(
            new WsServer(
                new RealTimeData()
            )
        ),
        8080
    );

    $server->run();

Now You call these WebSocket Services ( index.php )

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Hello</title>
</head>
<body>


    <script type="text/javascript">
        // When Single Connection
        var conn = new WebSocket('ws://localhost:8080');
        conn.onopen = function(e) {
            console.log("Connection established!");
            var data = {
                    'name': "kartik",
                    'age': 28,
                    'bio': {
                        'hobi': 'reading',
                        'skill': 'Codding'
                    }
            };
            conn.send(JSON.stringify(data));
        };

        conn.onmessage = function(e) {
            console.log(e.data);
        };

/*
        // you can route multiple socket connection
        var conn = new WebSocket('ws://localhost:8080/home');
        conn.onopen = function(e) {
            console.log("Connection established!");
            var data = {
                    'name': "kartik",
                    'age': 28,
                    'bio': {
                        'hobi': 'reading',
                        'skill': 'Codding'
                    }
            };
            conn.send(JSON.stringify(data));
        };

        conn.onmessage = function(e) {
            console.log(e.data);
        };


        var conn2 = new WebSocket('ws://localhost:8080/realtime');
        conn2.onopen = function(e) {
            console.log("Connection established!");
            var data = {
                    'name': "Its Stock Data",
                    'age': 28,
                    'bio': {
                        'hobi': 'reading',
                        'skill': 'Codding'
                    }
            };
            conn2.send(JSON.stringify(data));
        };

        conn2.onmessage = function(e) {
            console.log(e.data);
        };
*/
    </script>
</body>
</html>
