Question

I got an array and check if end() exists or is empty. If it is empty I would like to get the previous object of the array. I tried using prev() but that didn’t seem to work when applied to end().

any suggestions? the array can vary in lenght and size.

Thanks for your help guys!

Some code:

$pagination = esc_url( get_next_posts_page_link()); // returns url with slashes
$parts = explode('/', $pagination);
//get the last item
$tag = end($parts);
if ($tag == ""){echo prev($tag); } else{echo $tag;}

Answer 1

You should not apply prev() on the result of end() but on the original array as both functions are manipulating the internal array pointer of that array.

So:

if ($tag == ""){echo prev($parts); } else{echo $tag;}

Edit: By the way, you can also do a trim($pagination, '/') before you explode so that the last item will never be empty.
