swoole多个server监听不同端口如何相互转发消息？
比如同时监听10002、10003、10005进行tcp服务，端口10002连接客户端发送的消息直接转发到端口10003所有的客户端。

看看官方的示例代码
<?php
$server = new Swoole\WebSocket\Server("0.0.0.0", 9514, SWOOLE_BASE);
$tcp = $server->listen("0.0.0.0", 9515, SWOOLE_SOCK_TCP);
$tcp->set([]);
$server->on("open", function ($serv, $req) {
echo "new WebSocket Client, fd={$req->fd}\n";
});
$server->on("message", function ($serv, $frame) {
echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";
$serv->push($frame->fd, "this is server OnMessage");
});
$tcp->on('receive', function ($server, $fd, $reactor_id, $data) {
//仅遍历 9514 端口的连接，因为是用的$server，不是$tcp
$websocket = $server->ports[0];
foreach ($websocket->connections as $_fd) {
var_dump($_fd);
if ($server->exist($_fd)) {
$server->push($_fd, "this is server onReceive");
}
}
$server->send($fd, 'receive: '.$data);
});
$server->start();
