我正在编写一个 PHP 脚本，它会询问 4 个是/否问题，并根据答案显示你最后想到的动物，但它还没有完成。我已经完成了前 3 组问题，共 4 组，但我不知道如何显示最后一组问题，然后在不做大约 6 或 7 个 switch/if 语句的情况下显示答案，有没有更好的方法来做它比这，也许使用某种循环？下面是我到目前为止编写的代码，您可以在http://s504518.brunelweb.net/Creatures.php查看测验，尽管它还没有完成。任何帮助，将不胜感激。

我建议不要使用数组，而是创建下表

问题表

QId,Question

问题选项表

Qid, AID, Answer Description

问题流表

QId, AID, QID

当针对特定问题回答了问题时，您可以根据问题 ID 和答案 ID 推断下一个问题。添加新问题/更改问题流程也很简单。例如，根据您的图表，QuesitonsFlow 表将是这样的

QID | AnsID | NextQID
1   | 1     |  2
1   | 2     | 3

这样你就可以扩展你的桌子。
