$pipe = $codis_redis->multi(Redis::PIPELINE);
foreach($action_adids as $adid => $displaycount){
  $pipe->hIncrBy($adid, "cpm",                  $displaycount);
  $pipe->hIncrBy($adid, "cpm:" . date("Ymd"),   $displaycount);
  $pipe->hIncrBy($adid, "cpm:" . date("Ymd:H"), $displaycount);
}
$replies = $pipe->exec();
