Swoole怎么让一个服务监听多个端口

<?php
// 主服务监听 9501，处理普通 TCP 请求
$server = new Swoole\Server('0.0.0.0', 9501);

// 添加第二个端口 9502，也可指定不同 IP 或协议
$server->addlistener('0.0.0.0', 9502, SWOOLE_SOCK_TCP);

// 添加第三个端口，支持 SSL
$server->addlistener('0.0.0.0', 9503, SWOOLE_SOCK_TCP | SWOOLE_SSL);

// 设置回调函数（主端口）
$server->on('connect', function ($serv, $fd) {
    echo "Client: {$fd} connected to port " . $serv->ports[0]->port . "\n";
});

$server->on('receive', function ($serv, $fd, $reactor_id, $data) {
    $port = $serv->ports[0]->port;
    $serv->send($fd, "Received on port {$port}: " . trim($data) . "\n");
});

// 第二个端口的回调（可单独设置）
$port2 = $server->ports[1];
$port2->on('receive', function ($port, $fd, $reactor_id, $data) {
    $serv = $port->getServer();
    $serv->send($fd, "Reply from port 9502: " . trim($data) . "\n");
});

// 第三个端口（SSL）的回调
$port3 = $server->ports[2];
$port3->on('receive', function ($port, $fd, $reactor_id, $data) {
    $serv = $port->getServer();
    $serv->send($fd, "Secure reply from port 9503: " . trim($data) . "\n");
});

$server->start();

// 添加 UDP 端口
$server->addlistener('0.0.0.0', 9601, SWOOLE_SOCK_UDP);

$udpPort = $server->ports[3];
$udpPort->on('packet', function ($port, $data, $clientInfo) {
    echo "UDP packet from {$clientInfo['address']}:{$clientInfo['port']} \n";
    $port->send($clientInfo['address'], $clientInfo['port'], "UDP echo: " . $data);
});

$server->on('receive', function ($serv, $fd, $reactor_id, $data) {
    $info = $serv->connection_info($fd);
    $port = $info['server_port'];

    switch ($port) {
        case 9501:
            $serv->send($fd, "Processing as service A\n");
            break;
        case 9502:
            $serv->send($fd, "Processing as service B\n");
            break;
        case 9503:
            $serv->send($fd, "Processing secure request\n");
            break;
        default:
            $serv->send($fd, "Unknown port\n");
    }
});

// SSL 配置示例
$server->set([
    'ssl_cert_file' => '/path/to/ssl.cert',
    'ssl_key_file'  => '/path/to/ssl.key',
]);
