变量变量看起来很酷，但是我想不出一个在生产环境中实际使用它们的场景.这样的情况是什么?他们是如何使用的?

Variable variables seem pretty cool, but I can't think of a scenario where one would actually use them in a production environment. What would such a scenario be? How were they used?

推荐答案

我想，它的目的是允许新手程序员动态更改数据，而无需使用诸如复合类型(数组和对象)之类的复杂的东西".

Its purpose, I guess, is to allow novice programmers to dynamically change data without using "complicated stuff" like composite types (arrays and objects).

我从不使用它们.
