抢红包的原理
想用php实现抢红包的功能，谁发的红包越多，抢的也多，不知道要是什么算法合适
------解决思路----------------------
我想到个思路不知道合不合适（新手莫喷）
建立两个随机数，比如说一个是0-100 随机到多少给红包比如说这个数字是1-10对应获得红包，你的概率就是10%
另一个随机数范围0-50 随机获得一个数字比如也是1-10 对应获得红包这样概率就是20% 对面；
至于是第一种还是第二种就根据数据库中的top10 决定给那种吧
以上只是本人一点想法经此而已
------解决思路----------------------
你会记录每个人发的红包个数（金额数）
所以你会知道某个人发的红包个数（金额数），占整体红包个数（金额数）的比例
照此比例就可满足谁发的红包越多，抢的也多的要求

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
