Asynchronous object-oriented I/O PHP library
php-io is an object oriented and event-driven Input-Output library, primarily designed to serve network traffic to PHP scripts., (*1)
This library is partly based upon the php-uv's libuv binding, but other adapters are planned (pollig, libev, libevent), (*2)
The HTTP/WebSocket server example
A simple HTTP server could be implemented this way :, (*3)
<?php
use Gplanchat\Io\Adapter\Libuv\DefaultServiceManager as LibuvServiceManager;
use Gplanchat\Io\Application\Application;
use Gplanchat\Io\Net\Protocol\Http;
use Gplanchat\EventManager\Event;
use Gplanchat\Io\Net\Tcp\ClientInterface;
use Gplanchat\Io\Net\Tcp\Plugin\Server as TcpServerPlugin;
use Gplanchat\Io\Net\Protocol\Http\Plugin\Server as HttpServerPlugin;
$httpListener = function(Event $event, ClientInterface $client, Http\Request $request, Http\Response $response) {
$htmlBody = <<<HTML_EOF
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello world</h1>
</body>
</html>
HTML_EOF;
$response
->setHeader('Content-Type', 'text/html')
->setBody($htmlBody)
->setReturnCode(200, 'OK')
->emit(new Event('ready'))
;
};
(new Application(new LibuvServiceManager()))
->registerPlugin(new TcpServerPlugin(), 'TcpServer', 0)
->registerPlugin(new HttpServerPlugin($httpListener), 'HttpServer', 0)
->init(function(Event $event, Application $application) {
$application->callPlugin('TcpServer', ['0.0.0.0', 8081]);
$application->callPlugin('HttpServer', ['TcpServer', 200]);
})
->bootstrap()
->run()
;
Adding WebSocket support can be made this way by calling the init() method :, (*4)
->init(function(Event $event, Application $application) {
/*
* Adding WebSocket (RFC 6455) support
*/
$webSocketServiceManager = new WebSocket\ServerServiceManager();
$webSocketListener = function(Event $event, ClientInterface $client, WebSocket\Request $request, WebSocket\Response $response) {
$response
->addMessage(['Date' => date('c'), 'Hello' => 'World'])
->emit(new Event('ready'))
;
};
$httpServer = $application->getStorage('HttpServer');
$httpServer->registerPlugin('WebSocket', new Http\Plugin\WebSocket($webSocketServiceManager, $webSocketListener));
})
Using a database connection
For now, only MySQL using mysqli and mysqlnd is supported as a basic feature., (*5)
This is how you can implement a MySQL connection handler :, (*6)
use Gplanchat\Io\Application\Application;
use Gplanchat\EventManager\Event;
use Gplanchat\Io\Adapter\Libuv\DefaultServiceManager as LibuvServiceManager;
use Gplanchat\Io\Db\Mysql\DefaultServiceManager as MysqlServiceManager;
(new Application(new LibuvServiceManager()))
->init(function(Event $event, Application $application) {
// Initiating the poller and assigning it to the main loop through a timer
/** @var \Gplanchat\Io\Loop\TimerInterface $timer */
$timer = $application->getServiceManager()->get('Timer', [$application->getCurrentLoop()]);
$serviceManager = new MysqlServiceManager();
$poller = $serviceManager->get('Poller');
$link = $serviceManager->get('Connection', ['localhost', 'root', '', 'foo_database']);
$poller->addConnection($link);
$timer->interval(1, $poller);
$application->setStorage('Db', $link);
})
->init(function(Event $event, Application $application) {
// Sending requests to the RDBMS
$worker = $application->getServiceManager()->get('Timer', [$application->getCurrentLoop()]);
$worker->interval(20, function() use($application) {
$link = $application->getStorage('Db');
$link->query('SELECT * FROM foo_table ORDER BY RAND() LIMIT 1', function($result) {
var_dump($result);
});
});
})
->bootstrap()
->run()
;
