How to determine the first and last iteration in a foreach loop?

Question

The question is simple. I have a `foreach` loop in my code: foreach($array as $element) { //code } In this loop, I want to react differently when we are in first or last iteration. How to do this?

Answer 1

I use a counter variable that increments with each loop. Comparing that to zero or one, and the size of what you are iterating on you can decide what to do.
