pipeline()

批量执行命令，然后结果一次性返回

$pipe = $redis->pipeline();
foreach ($cityCinemaIdData as $cityId => $cinemaIdData) {
    $cityIdKey = 'cinema_list:city_id:' . $cityId;
    $pipe->del($cityIdKey);
    $pipe->rpush($cityIdKey,$cinemaIdData);//$cinemaIdData是一组value,也可以是单个value
　　 $pipe->expire($cityIdKey,cmsRedis::ExpireOneDay); 
}
