gatewayworker在events的onmessage回调中如何获取到worker进程

class Events
{
    public static function onWorkerStart($worker)
    {
        //比如只给0号进程设置定时器
        if($worker->id === 0)
        {
            Timer::add(1, function(){
               //业务逻辑
            });
        }
    }
}

if($worker->id === 0)
{
    Timer::add(1, function(){
        //业务逻辑
    });
}

public static function onWorkerStart($worker)
{   
    empty(self::$worker) && self::$worker = $worker;
}
