PHP递归写入MySQL无限级分类数据，表结构：

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;

递归方法代码：

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;
    }

调用代码：

KeplerCategory::addCategoryFromKepler(0);

递归方法读取代码：

static public function getCategoryFormatToKepler($parentid, $format_data = array(), $parent_prefix = '', $current_prefix = ''){
        $category_list = self::getCategoryByParentid($parentid); // 根据父ID获取
        if(!empty($category_list)){
            foreach ($category_list as $key => $value) {
                $format_data = self::getCategoryFormatToKepler($value['id'], $format_data, $parent_prefix . ',' . $current_prefix, $value['kepler_fid']);
            }
        }else{
            $format_data[] = trim($parent_prefix . ',' . $current_prefix, ',');
        }
        return $format_data;
    }

调用代码：

$category_list = KeplerCategory::getCategoryFormatToKepler(0);
