启动了swoolewebsocket服务后如何修改代码即时生效？

//创建websocket服务器对象，监听0.0.0.0:9502端口

$ws_server = new swoole_websocket_server('192.168.183.200', 9502);



//设置server运行时的各项参数

$ws_server->set(array(

    'daemonize' => true, //是否作为守护进程

));



//监听WebSocket连接打开事件

$ws_server->on('open', function ($ws, $request) {

    $ws->push($request->fd, "Hello, Welcome\n");

});



//监听WebSocket消息事件

$ws_server->on('message', function ($ws, $frame) {

    pushMessage($ws,$frame);

});



//监听WebSocket连接关闭事件

$ws_server->on('close', function ($ws, $fd) {

    echo "client-{$fd} is closed\n";

});



$ws_server->start();



//消息推送

function pushMessage($ws,$frame){

    $ws->push($frame->fd, $frame->fd.' : '.$data.'这里是推送给用户的内容，待会我想修改');

}
