I have an idea that's probably beyond most procedural languages..as a
straight coding exercise BUT you MAY be able to do it as a recursive call

Consider the following

function loopy($i)
{
while ($i && (something else))
{
// do your loopy stuff.
}
$i--;
if($i>0)
$i=loopy($i);
return $i;
}

That will exercise the same loop $i times.
