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;

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
