README

Important

This repository is a read-only mirror of the utopia-php monorepo. Development happens in packages/websocket — please open issues and pull requests there.

Utopia WebSocket is a simple and lite abstraction layer around a WebSocket server. This library is aiming to be as simple and easy to learn and use. This library is maintained by the Appwrite team.

Although this library is part of the Utopia Framework project it is dependency free and can be used as standalone with any other PHP project or framework.

Getting started

Install using Composer:

composer require utopia-php/websocket

Init in your application:

<?php

require_once __DIR__ . '/../../vendor/autoload.php';

use Utopia\WebSocket;

$adapter = new WebSocket\Adapter\Swoole();
$adapter->setPackageMaxLength(64000);

$server = new WebSocket\Server($adapter);
$server->onStart(function () {
    echo "Server started!";
});
$server->onWorkerStart(function (int $workerId) {
    echo "Worker {$workerId} started!";
});
$server->onOpen(function (int $connection, $request) {
    echo "Connection {$connection} established!";
});
$server->onMessage(function (int $connection, string $message) {
    echo "Message from {$connection}: {$message}";
});
$server->onClose(function (int $connection) {
    echo "Connection {$workerId} closed!";
});

$server->start();

System requirements

Utopia Framework requires PHP 8.0 or later. We recommend using the latest PHP version whenever possible.

Testing

composer test       # unit tests, with no servers
composer test:e2e   # starts local Swoole and Workerman fixture servers
