PHP做排行榜功能,求思路
简述:
有一用户系统
用户有:经验值、积分值、...
现想做上述N种值的排行榜,如积分排行榜类型有:总榜、今日榜;用户与其好友进行排行的总榜、今日榜

条件:
1、用户数目前2KW左右,还持续增长
2、排出前1W名
3、上榜中的每个用户要求展示其本次排名与上次排名是提升、下降还是相等

可选:
redis、memcache、mysql

脚本:

3、上榜中的每个用户要求展示其本次排名与上次排名是提升、下降还是相等
所以你必须将查询结果置于表中

接下来就都很容易了,只是按需构造一个查询指令而已
------解决方案--------------------
用REDIS吧。。
sorted set型存uid和名次,正好uid做分数。
再弄个hash型,存具体信息,上次排名,提升还是下降等。
------解决方案--------------------
楼主。这2KW数据是用什么保存的呀?  CSDN 怎么设置有回帖提醒!??
------解决方案--------------------
一般是定时执行查询,根本就不是实时的。

------解决方案--------------------
见识过了 怎么没解决方案?
------解决方案--------------------
只要精心设计好数据结构,用php动态排1万名应该还是有可能的。
