How to add div to the last post and every 5th post

Question

The loop it is currently set to add a 'review' every 5th project post, I would like it to do this and add a 'review' after the last post. For example, if there are 13 posts it adds a 'review' after the 5th, 10th, and 13th post.

I have tried doing a post count and adding that as an 'or' statement, however, that just tries to add a 'review' after every post.

There are a number of ways to achieve this but basically you want to use modulo at the end of your loop to avoid duplicates.

Let's say that you have a loop with a counter and that loop does 10, 15 or 20 iterations. At the end of the loop (outside of your loop) you want to check that counter:

echo $counter % 5 === 0 ? '' : $lastReview;

If the remainder of $counter divided by 5 equals 0 you php won't echo a review, otherwise, it will.
