    //@获取子栏目ID号    private function sonCategoryIds($categoryID)    {        //@初始化栏目数组        $array[] = $categoryID;                do        {            $ids = '';            $temp = $this->mysql->select('SELECT `id` FROM `pcb_article_category` WHERE `parentID` IN (' . $categoryID . ')');            foreach ($temp as $v)            {                $array[] = $v['id'];                $ids .= ',' . $v['id'];            }            $ids = substr($ids, 1, strlen($ids));            $categoryID = $ids;        }        while (!empty($temp));        $ids = implode(',', $array);                return $ids;    }
