A better way:

function GetItemIds($num = 10) {
    $q = "SELECT item_id FROM common.items ORDER BY item_id DESC LIMIT " . $num;
    $result = mysql_query($q);
    $ids = array();
    while($row = mysql_fetch_assoc($result)) {
        $ids[] = $row['item_id'];
    }
    return implode(',', $ids);
}

echo GetItemIds();
