PHP递归写入MySQL实现无限级分类数据操作示例_php技巧_

 CREATE TABLE `kepler_goods_category` ( `id` int unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT, `parentid` int unsigned NOT NULL default 0 comment '父级分类ID', `name` varchar(255) NOT NULL default '' comment '分类名称', `kepler_fid` int unsigned NOT NULL default 0 comment '对应开普勒分类ID', `create_time` timestamp NOT NULL default CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ) ENGINE=InnoDB DEFAULT CHARSET=utf8; 

 static public function addCategoryFromKepler($fid, $parentid = 0){ $category_list = Kepler::queryGoodsCategoryList($fid); // 获取数据 $category_list = $category_list['jd_kepler_item_querycategoriesbyfid_response']; if($category_list['total'] > 0){ foreach ($category_list['categories'] as $key => $value) { $parentid_sub = KeplerCategory::addCategory($value['name'], $value['id'], $parentid); // 插入数据库，得到父ID self::addCategoryFromKepler($value['id'], $parentid_sub); // 递归 } } return true; }
