用lua 给redis 中塞值要怎设置有效时间

不存在现成的方法

如果要实现你说的功能
一般来说 还是按照正常的方法通过insert 或remove对表进行值的增减
然后再额外的对表进行一个监听 当达到规定时间的时候,remove掉相关的值
 

php redis 怎解决回复功可以

redis会将数据存储在内存中,断电丢失。这个要注意一下,如有必要就做个持久化。持久化的方法一言难尽,可以参考网上的文章。

php的redis扩展叫php-redis。网上有php-redis的中文手册,下面给你一个示例:
connect('127.0.0.1', 6379); // 6379是默认端口$result = $redis->set('9639002718',"comment"); // 设置键值echo $result = $redis->get('9639002718'); // 获取键值$all = $redis->getMultiple(array('9639002718', '9639002718')); // 同时获得多个键值// 没有提供获得所有键值的方法。下面这句我不确定是否能用,你可以试一试。$all = $redis->getMultiple(array('*'));
望采纳,谢谢支持!
