Bloatless PHP WebSockets

Simple WebSocket server and client implemented in PHP.

About

This application is an extremely simple implementation of the WebSocket Protocol in PHP. It includes a server as well as a client. This implementation is optimal to get started with WebSockets and learn something. As soon as you want to create a full featured websocket based application you might want to switch to more sophisticated solution.

Installation

Clone or download the repository to your server. The package is also installable via composer running the following command:

composer require bloatless/php-websocket

Requirements

  • PHP >= 7.2

Hint: You can use version 1.0 if you're still on PHP5.

Usage

  • Adjust
    cli/server.php
    to your requirements.
  • Run:
    php cli/server.php

This will start a websocket server. (By default on localhost:8000)

Server example

This will create a websocket server listening on port 8000.

There a two applications registred to the server. The demo application will be available at

ws://localhost:8000/demo
and the status application will be available at
ws://localhost:8000/status
.
// Require neccessary files here...

$server = new \Bloatless\WebSocket\Server('127.0.0.1', 8000);

// Server settings: $server->setMaxClients(100); $server->setCheckOrigin(false); $server->setAllowedOrigin('foo.lh'); $server->setMaxConnectionsPerIp(100); $server->setMaxRequestsPerMinute(2000);

// Add your applications here: $server->registerApplication('status', \Bloatless\WebSocket\Application\StatusApplication::getInstance()); $server->registerApplication('demo', \Bloatless\WebSocket\Application\DemoApplication::getInstance());

$server->run();

Client example

This creates a WebSocket cliente, connects to a server and sends a message to the server:

$client = new \Bloatless\WebSocket\Client;
$client->connect('127.0.0.1', 8000, '/demo', 'foo.lh');
$client->sendData([
    'action' => 'echo',
    'data' => 'Hello Wolrd!'
]);

Browser example

public
folder. The
index.html
is a simple application which you can use to send messages to the server.

status.html
