Foreach Loop

[Mythotical]

I'm trying loop categories so I get main category then the sub cats listed below them for a download section mod I'm building.

Here's the code thus far:

PHP Code:

     $cats = $vbulletin->db->query("SELECT * FROM `" . TABLE_PREFIX . "xsdl_cats` WHERE sub_cat = '0' AND par_cat = '0'");

    while($category = $vbulletin->db->fetch_array($cats))
        {
                $cid = $category['cid'];
                $cname = $category['cat_name'];
                // $rating = round($entry['rating']);
                $description = $category['description'];
                $subcat = $category['sub_cat'];
                $file_loc = $category['file_loc'];
                $screen_loc = $category['screen_loc'];
 
                $query = $db->query_first("
                      SELECT COUNT(`dlid`) AS `total`
                    FROM `" . TABLE_PREFIX . "xs_downloads`
                    WHERE cat_id = " . $category['cid'] . "
                ");
 
                $subs = $vbulletin->db->query("SELECT * FROM `" . TABLE_PREFIX . "xsdl_cats` WHERE sub_cat = '1' AND par_cat = '$cid'");
                while($sub_cats = $vbulletin->db->fetch_array($subs))
                {
                    $scid = $sub_cats['cid'];
                    $scname = $sub_cats['cat_name'];
                    // $srating = round($sub_cats['rating']);
                    $sdescription = $sub_cats['description'];
                    $ssubcat = $sub_cats['sub_cat'];
                    $sfile_loc = $sub_cats['file_loc'];
                    $sscreen_loc = $sub_cats['screen_loc'];
                }
 
                $count = $query['total'];
                $key[0] = $cid;
                $key[1] = $cname;
                $key[2] = $description;

                foreach ($key as $value)
                {
                echo $value;
                    $sub[0] = $scid;
                    $sub[1] = $scname;
                    $sub[2] = $sdescription;
                    foreach ($sub as $value)
                        {
                        echo '<a href="downloads.php?do=cat&amp;id=' . $value . '">' . $value . '</a><br />' . $value . '';
                        }
                } 


Any help much appreciated.
