    Do you have at least some assumptions, how to go through a two-dimensional array, how to compare elements? Have you tried to look at the "similar" questions and answers that the site offered you in the panel on the right? - Kromster

You can use foreach, you can use for, while, while / do, it will be the simplest and most readable solution.

You can also use array_walk or array_map to solve this problem in a functional style.

But I would recommend you to use recursive functions in order not to bother with the nesting of the array.
