每1个进程设置一个定时器的问题？

$worker->onWorkerStart = function($worker) {
    if($worker->id === 0)
    {
        Timer::add(2, function(){
            broadcast(222);
        });
    }

    if($worker->id === 1)
    {
        Timer::add(3, function(){
            broadcast(333);
        });
    }
};

function broadcast($message)
{
    global $worker;
    foreach($worker->connections as $connection)
    {
        $connection->send($message);
    }
}
