This is a three-dimensional array, get it!

I won’t talk about the first loop, just get the index and value of the first layer;

The second loop is to get the index and value of the second loop, and the third loop is Get the index and value of the third loop

Answer 5

What effect do you want? Generally use foreach to traverse

Answer 6

I don’t understand what you want to do, traverse the array, how do you want to traverse it? What are the requirements?
