<?php
//创建Server对象，监听 127.0.0.1:9502端口，类型为SWOOLE_SOCK_UDP
$serv = new swoole_server("127.0.0.1", 9502, SWOOLE_PROCESS, SWOOLE_SOCK_UDP);

$serv->set([
    'worker_num' => 4,    //worker进程数   一般是cpu的倍数
    'max_request' => 1000      //最大请求数
]);

//监听数据接收事件
$serv->on('Packet', function ($serv, $data, $clientInfo) {
    $serv->sendto($clientInfo['address'],$clientInfo['port'], "Server ".$data);
    var_dump($clientInfo);
