本文实例讲述了PHP递归写入MySQL实现无限级分类数据操作。分享给大家供大家参考，具体如下：
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;
递归方法写入代码：
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);
希望本文所述对大家PHP程序设计有所帮助。
