Event-driven, non-blocking I/O with PHP.

The recommended way to install react is through composer.

{
    "require": {
        "react/react": "dev-master"
    }
}

• Usable with a bare minimum of PHP extensions, add more extensions to get better performance.
• Provide a standalone event-loop component that can be re-used by other libraries.
• Decouple parts so they can be replaced by alternate implementations.

React is non-blocking by default. Use workers for blocking I/O.

Both React\Socket\Server and React\Socket\Connection extend événement, allowing you to bind to events.

Here is an example of a simple HTTP server listening on port 1337:

<?php

$i = 1;

$app = new React\Espresso\Application();

$app->get('/favicon.ico', function ($request, $response) {
    $response->writeHead(204);
    $response->end();
});

$app->get('/', function ($request, $response) use (&$i) {
    $i++;

    $text = "This is request number $i.\n";
    $headers = array('Content-Type' => 'text/plain', 'Content-Length' => strlen($text));

    $response->writeHead(200, $headers);
    $response->end($text);
});

$stack = new React\Espresso\Stack($app);
$stack->listen(1337);
