#Ratchet
|
|
|
|
[](http://travis-ci.org/cboden/Ratchet)
|
|
|
|
A PHP 5.3 library for serving WebSockets and building socket based applications.
|
|
Build up your application through simple interfaces and re-use your application without changing any of its code just by combining different components.
|
|
|
|
##WebSocket Compliance
|
|
|
|
* Supports the RFC6455, HyBi-10+, and Hixie76 protocol versions (at the same time)
|
|
* Tested on Chrome 13 - 19, Firefox 6 - 12, Safari 5.0.1+, iOS 4.2, iOS 5
|
|
|
|
##Requirements
|
|
|
|
Shell access is required and a dedicated machine with root access is recommended.
|
|
To avoid proxy/firewall blockage it's recommended WebSockets are run on port 80, which requires root access.
|
|
Note that you can not run two applications (Apache and Ratchet) on the same port, thus the requirement for a separate machine (for now).
|
|
PHP 5.3.2 (or higher) is required with mbstring enabled (*--enable-mbstring* flag during compile time). PHP5.4 is recommended for its performance improvements.
|
|
|
|
Cookies from your domain will be passed to the socket server, allowing you to identify users.
|
|
Accessing your website's session data in Ratchet requires you to use [Symfony2 Sessions](http://symfony.com/doc/master/components/http_foundation/sessions.html) on your website.
|
|
|
|
### Documentation
|
|
|
|
User and API documentation is available on Ratchet's website: http://socketo.me
|
|
|
|
See https://github.com/cboden/Ratchet-examples for some out-of-the-box working demos using Ratchet.

###A quick server example
|
|
|
|
```php
|
|
<?php
|
|
use Ratchet\MessageComponentInterface;
|
|
use Ratchet\ConnectionInterface;
|
|
use Ratchet\Server\IoServer;
|
|
use Ratchet\WebSocket\WsServer;
|
|
|
|
/**
|
|
* chat.php
|
|
* Send any incoming messages to all connected clients (except sender)
|
|
*/
|
|
class Chat implements MessageComponentInterface {
|
|
protected $clients;
|
|
|
|
public function __construct() {
|
|
$this->clients = new \SplObjectStorage;
|
|
}
|
|
|
|
public function onOpen(ConnectionInterface $conn) {
|
|
$this->clients->attach($conn);
|
|
}
|
|
|
|
public function onMessage(ConnectionInterface $from, $msg) {
|
|
foreach ($this->clients as $client) {
|
|
if ($from != $client) {
|
|
$client->send($msg);
|
|
}
|
|
}
|
|
}
|
|
|
|
public function onClose(ConnectionInterface $conn) {
|
|
$this->clients->detach($conn);
|
|
}
|
|
|
|
public function onError(ConnectionInterface $conn, \Exception $e) {
|
|
$conn->close();
|
|
}
|
|
}
|
|
|
|
// Run the server application through the WebSocket protocol on port 8000
|
|
$server = IoServer::factory(new WsServer(new Chat), 8000);
|
|
$server->run();
|
|
```
