swooleUDP

1：创建服务端文件UDP.php

<?php

class UDP
{
    private $server = null;
    
    public function __construct(){
        $this -> server = new Swoole\Server('127.0.0.1', 9502, SWOOLE_PROCESS, SWOOLE_SOCK_UDP);
        
        //监听数据接收事件
        $this -> server->on('Packet', [$this,"onPacket"]);
        
        //启动服务器
        $this -> server->start();
    }
    
    public function onPacket($server, $data, $clientInfo){
        var_dump($clientInfo);
        $server->sendto($clientInfo['address'], $clientInfo['port'], "Server：{$data}");
    }
}
new UDP();

2：创建客户端文件UDP.php

<?php

// use Swoole\Coroutine\Client;
// use function Swoole\Coroutine\run;

go(function () {
    $client = new Swoole\Coroutine\Client(SWOOLE_SOCK_UDP);
    if (!$client->connect('127.0.0.1', 9502, 0.5))
    {
        echo "connect failed. Error: {$client->errCode}\n";
    }
    // fwrite(STDOUT,"请输入：");
    // $res = fgetc(STDIN);
    // $client->send($res);
    $client->send("你好!");
    echo $client->recv();
    $client->close();
});
