I don't think that it does this:

if ( count($elements) == 1 ) then loop 1;
else loop normally;

It's probably more something like that:

$i=count($elements);
loop:
$i--;
if($i == 0)
    $last_loop = true;
else
    $last_loop = false

if($last_loop)
   exit;
else
   goto loop;



But aside from that, I would propose you the same thing Robert already
did - Just use while or some other loop (for maybe?).
