Swoole を使用して高性能ネットワーク サーバーを開発する方法

$ pecl install swoole

extension=swoole.so

<?php
$http = new swoole_http_server("127.0.0.1", 9501);

$http->on('request', function ($request, $response) {
    $response->header("Content-Type", "text/html; charset=utf-8");
    $response->end("<h1>Hello Swoole!</h1>");
});

$http->start();

$ php server.php

<?php
$ws = new swoole_websocket_server("127.0.0.1", 9502);

$ws->on('open', function ($ws, $request) {
    echo "client-{$request->fd} is connected
";
});

$ws->on('message', function ($ws, $frame) {
    echo "received message: {$frame->data}
";
    foreach($ws->connections as $fd) {
        $ws->push($fd, $frame->data);
    }
});

$ws->on('close', function ($ws, $fd) {
    echo "client-{$fd} is closed
";
