How to take the current key from array? PHP

Question

Hello,

I want to take the current key in the array. I know the function current($array) but it take the value.

Rules:

1. I cannot use in any loop.
2. Without array_flip().
3. I need function.. if you can mix the function current($array) it'll be great!

Thank you.
