背景:对连续签到的系统进行递级给积分,并且连续签到有一定的积分奖励,并且用户连续签到30天给比较多的积分。
要求:并不是按照自然月来签到。
怎么判断是不是连续签到呢?
然后就是数据库怎么设计好呢,因为并不是按照自然月来签到,连续签到的话都是跨月的了。

怎么判断是不是连续签到呢?
然后就是数据库怎么设计好呢,因为并不是按照自然月来签到,连续签到的话都是跨月的了。
记录一个人当次连续第1天的日期和最后1天的日期,签到的时候判断是否连续。如果连续,可以计算出来连续天数。如果不连续,重置连续第1天和最后1天的日期为当前签到日期。
如果需要记录签到,专门用一张表来记录。可以按月,即每一月一条数据来记录,也可以按年记录。如果按天记录的话数据量太大,没啥必要。
这个数据库设计不想的太复杂,签到系统其实逻辑判断比较重要。我前几天刚好做了一个,只需要把时间格式化,去掉时分秒,如20150907,之后的话只需要判断前边的几天时间记录是否相邻即可。
一个字段记录连续签到次数,一个字段记录最后一次签到的时间!
每次签到
判断:检查上次签到时间和现在的签到时间中间是否为1天
是:
<code>签到次数+1;</code>
不是:
<code>签到次数=0</code>
更新最后的签到时间为现在时间;

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
