The Hoa\Websocket library.
Hoa is a modular, extensible and
structured set of PHP libraries.
Moreover, Hoa aims at being a bridge between industrial and research worlds.
This library allows to manipulate the WebSocket protocol and proposes a server and a client. It supports two specifications RFC6455 and Hybi (at the same time).
With Composer, to include this library into your dependencies, you need to require
hoa/websocket:
$ composer require hoa/websocket '~3.0'
For more installation procedures, please read the Source page.
Before running the test suites, the development dependencies must be installed:
$ composer install
Then, to run all the test suites:
$ vendor/bin/hoa test:run
For more information, please read the contributor guide.
As a quick overview, we propose to start a websocket server and echo messages. The class
Hoa\Websocket\Serverproposes six listeners:
open,
message,
binary-message,
ping,
closeand
error. Thus:
$websocket = new Hoa\Websocket\Server( new Hoa\Socket\Server('ws://127.0.0.1:8889') ); $websocket->on('open', function (Hoa\Event\Bucket $bucket) { echo 'new connection', "\n";return;
}); $websocket->on('message', function (Hoa\Event\Bucket $bucket) { $data = $bucket->getData(); echo '> message ', $data['message'], "\n"; $bucket->getSource()->send($data['message']); echo '< echo', "\n";
return;
}); $websocket->on('close', function (Hoa\Event\Bucket $bucket) { echo 'connection closed', "\n";
return;
}); $websocket->run();
Finally, we have to write a client in HTML and Javascript:
Here we are. All sent messages are echoed.
