@flavius yeah I agree $last can a "dangerous" variable for this. This was just for showing. It also requires for two elements to be missing as well. But it was just to illustrate that this was simpler than array_map. I wasn't actually able to make array_map work in this situation, which was why I looked elsewhere for a solution.
