고성능 온라인 게임 개발을 위해 PHP와 Swoole을 어떻게 사용합니까?

$ sudo apt-get install php-pear

$ sudo pecl install swoole

extension=swoole.so

$server = new SwooleServer('0.0.0.0', 9501);

$server->on('connect', function ($server, $fd) {
    echo "Client [{$fd}] connected." . PHP_EOL;
});

$server->on('receive', function ($server, $fd, $fromId, $data) {
    echo "Received data from client [{$fd}]: {$data}" . PHP_EOL;

    // 处理收到的数据，如解析游戏指令等
    // ...

    // 向客户端发送响应数据
    $server->send($fd, 'Hello, client!');
});

$server->on('close', function ($server, $fd) {
    echo "Client [{$fd}] closed." . PHP_EOL;
});

$server->start();

$server = new SwooleWebSocketServer('0.0.0.0', 9501);

$server->on('open', function ($server, $request) {
    echo "Client [{$request->fd}] connected." . PHP_EOL;
});

$server->on('message', function ($server, $frame) {
    echo "Received message from client [{$frame->fd}]: {$frame->data}" . PHP_EOL;

    // 处理收到的消息，如解析游戏指令等
    // ...

    // 向客户端发送响应消息
    $server->push($frame->fd, 'Hello, client!');
});

$server->on('close', function ($server, $fd) {
    echo "Client [{$fd}] closed." . PHP_EOL;
});

$server->start();

$server = new SwooleHttpServer('0.0.0.0', 9501);

$server->on('request', function ($request, $response) {
    $db = new SwooleCoroutineMySQL();

    $db->connect([
        'host' => '127.0.0.1',
        'port' => 3306,
        'user' => 'root',
        'password' => 'root',
        'database' => 'game_db',
    ]);

    $result = $db->query('SELECT * FROM users');

    $db->close();

    $response->header('Content-Type', 'application/json');
    $response->end(json_encode($result));
});

$server->start();
