• check-origin
• limit clients
• sends status codes on close connections
• sends custom headers

Requirements

PHP >= 7.0

Installation

Enter in composer.json

{
    "require": {
        "hemiframe/php-websocket": "~1.7"
    }
}

How to run demo?

Open CMD or terminal and enter

php demo/server.php

After that you can open demo/index.html in your browser

Server example

require_once('vendor/autoload.php');

$socket = new \HemiFrame\Lib\WebSocket\WebSocket("localhost", 8080);
$socket->on("receive", function($client, $data) use($socket) {
	foreach ($socket->getClients() as $item) {
        /* @var $item \HemiFrame\Lib\WebSocket\Client */
		if ($item->id != $client->id) {
			$socket->sendData($item, $data);
		}
	}
});
$socket->startServer();

Client example

require_once('vendor/autoload.php');

$socket = new \HemiFrame\Lib\WebSocket\WebSocket('localhost', 8080);
$socket->on("receive", function($client, $data) use($socket) {
});
$client = $socket->connect();
if ($client) {
	$socket->sendData($client, "Message");
	$socket->disconnectClient($client);
}
