PHP 非同步程式設計指南：探索事件循環和非阻塞 I/O

$loop = React\EventLoop\Factory::create();

//添加文件监听器
$loop->addReadStream($file, function($stream) {
    //处理文件输入
});

//添加网络连接监听器
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
$socket->on('connection', function(React\Socket\ConnectionInterface $connection) {
    //处理客户端连接
});

$loop->run();

$file = fopen('file.txt', 'r');

//异步读取文件
fread($file, 1024, function($data) {
    //处理数据
});

fclose($file);

use React\Http\Response;
use React\Http\Server;

$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);

$server = new Server(function (Psr\Http\Message\ServerRequestInterface $request) {
    return new Response(200, ['Content-Type' => 'text/plain'], 'Hello World!');
});

$server->listen($socket);
$loop->run();
