我的测验问题是静态的，即用户可以做一些谷歌搜索来回答我不想要的问题，所以我想生成随机问题，然后给他们打分，但不知道怎么做。我想使用数据库rand()问题。我已经有了这个从数据库生成10个随机问题：

select*from (select*from quiz where level between 1 and 10 order by rand()) tmp group by level order by level

所以我需要的是对生成的随机问题进行评分。我不知道如何编码。

Answer 1

很难理解你的意思，但是要将随机问题包含在测验中，我会按如下方式构建它： 1）将所有问题，答案和正确答案存储在MySQL数据库表中。 2）在数据库中有相同问题的多个版本。 3）让PHP从数据库中选择问题的随机版本 4）加载问题并使用PHP为它们构建HTML。

如何生成随机测验问题并对其进行评分？
