老师,您好我想在客户端链接后做个1000毫秒tick定时器,5000毫秒后结束tick定时器。

 public function onOpen($ws, $request)
    {
        var_dump($request->fd);
        $ws->push($request->fd,'欢迎链接，' . $request->fd);
        Swoole_timer_tick(1000,function($timer) use($ws,$request){
            $ws->push($request->fd,'现在开始进行攻击,伤害：100');
            $this->timer_id = $timer;
        });
        $timer = $this->timer_id;
        Swoole_timer_after(5000,function() use($ws,$request,$timer){
            Swoole_timer_clear($timer);
            $ws->push($request->fd,'攻击完成!成功击毙敌人');
        });
        $ws->push($request->fd,'发现敌人，准备进行攻击');
    }

结果是5000毫秒后tick没有关闭还在继续执行。我看不出哪里有什么不对
运行结果
