Wrench

A simple PHP WebSocket implementation.

Installation

The library can be installed with Composer and is available on Packagist under chrome-php/wrench:

$ composer require chrome-php/wrench

PHP 7.4-8.5 are currently supported, only.

Usage

This creates a server on 127.0.0.1:8000 with one Application that listens for WebSocket requests to ws://localhost:8000/echo and ws://localhost:8000/chat:

Server

// An example application, that just echoes the received
// data back to the connection that sent it
$app = new class implements \Wrench\Application\DataHandlerInterface
{
    public function onData(string $data, \Wrench\Connection $connection): void
    {
        $connection->send($data);
    }
};

// A websocket server, listening on port 8000
$server = new \Wrench\BasicServer('ws://localhost:8000', [
    'allowed_origins' => [
        'mysite.com',
        'mysite.dev.localdomain'
    ],
]);

$server->registerApplication('echo', $app);
$server->registerApplication('chat', new \My\ChatApplication());
$server->setLogger($monolog); // PSR3
$server->run();

Client

// A client side example, that sends a string and will receive
// the data back to the connection that sent it
$client = new Client('ws://localhost:8000', 'http://localhost:8000');
$client->connect();
$client->sendData('hello');
$response = $client->receive(5.0)[0]->getPayload();
$client->disconnect();
