Thanks! I fixed my while loops and am not getting any warnings. I haven't got the answer yet, though. 

    $counter = $i + 1;
    while ($forest[$current][$counter] < $forest[$current][$i] and $fo
+und == 0)
    {
        $counter += 1;
        if ($counter == 99)
        {
            $visible += 1;
            $found = 1;
            $counter = 1;
        }
    }
