网上好多,类似什么算命啊,看看你下辈子什么的
就是输入同一个人名,出来结果都是一样的,
我想做个,但是不知道这数据结构,以及程序怎么设计,
输入相同的字词,出来的结果必须一样,
我本想做个列表,但是想想这个记录表,得多大啊,头疼!
回复讨论(解决方案)
你看看这样的想法行不行,进来一个 name 先去数据库找,如果已经存在,就取出结果,如果没有,就随机给结果,并存到数据库中。如果想更完美点,就中间放一层缓存 redis或者memcache
伪科学!
输出结果都是随机产生的
伪随机数发生器 rand 是可以播种种子的,相同的种子将产生相同的伪随机数序列
因此,只需将传入的数据做为种子就可以了
srand(hexdec(md5($input, 1)));

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.

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.
