Row count

[Mythotical]

Did anything change how row count is done?

PHP Code:

$sql = $vbulletin->db->query_read("SELECT * FROM `" . TABLE_PREFIX . "download_cats` WHERE cat_active = '1'");

$total = $vbulletin->db->num_rows($sql);
$i=0;
$perrow = $total-2;

while ($row = $db->fetch_array($sql))
{
        $i++;

    if ($total !== 0)
    {
  
    if ($total > $perrow){
        $catc = '</td>';
        $perrow = $perrow+2;
    } else {
        $perrow = $perrow-2;
        $catc = '</td></tr><tr>';
    } 


I'm not sure if that is the problem but when I refresh my page is keeps displaying:

</td></td></tr><tr>

Not sure if its the row count or not. Hard to say right now.

Thanks
