swoole之TCP服务器

<?php
//创建Server对象，监听 127.0.0.1:9501端口
$serv = new swoole_server("127.0.0.1", 9501);

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

//监听连接进入事件
//$fd  客户端连接的唯一标识
//$reactor_id   线程
$serv->on('connect', function ($serv, $fd,$reactor_id) {
    echo "Client:{$reactor_id}-{$fd}-Connect.\n";
});

//监听数据接收事件
$serv->on('receive', function ($serv, $fd, $reactor_id, $data) {
    $serv->send($fd, "Server: {$reactor_id}-{$fd}-".$data);
});

//监听连接关闭事件
$serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";

//启动服务器
$serv->start();
