 DownloadSocket 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>
