如果我有

$abc = '123';

我如何在write内部找出现在由$var表示的变量称为$abc?

How would I inside write find out that the variable now represented by $var was called $abc?

推荐答案

这是不可能的.即使是按引用传递也不会帮助您.您必须将名称作为第二个参数传递.

It's not possible. Even pass-by-reference won't help you. You'll have to pass the name as a second argument.

但是您肯定要问的是 并不是解决问题的好方法.

But what you have asked is most assuredly not a good solution to your problem.
