服务端：

<?php
$server = new Swoole\Server('127.0.0.1', 9504, SWOOLE_PROCESS, SWOOLE_SOCK_UDP);

$server->on('start', function ($server) {
    echo "UDP Server is started at udp://127.0.0.1:9504\n";
});
    
$server->on('packet', function ($server, $data, $clientInfo) {
    echo "接收到客户端数据：{$data}，来自{$clientInfo['address']}:{$clientInfo['port']}\n";
    $server->sendTo($clientInfo['address'], $clientInfo['port'], "我收到你的消息了");
});
    
$server->start();

　　客户端：

<?php
$client = new Swoole\Client(SWOOLE_SOCK_UDP);
$client->sendto('127.0.0.1', 9504, "测试一下");
echo "收到服务端回复：".$client->recv();

//var_dump($client->isConnected());

//$socketinfo = $client->getsockname();
//print_r($socketinfo);

//$peerinfo = $client->getpeername();
//print_r($peerinfo);

$client->close();

　　输出：
