$server = new Swoole\HTTP\Server("127.0.0.1", 9501);

$server->on("Start", function(Server $server)
{
    echo "Swoole http server is started at http://127.0.0.1:9501\n";

$server->on("Request", function(Request $request, Response $response)
{
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World\n");
