三级分类 like查询 查询到很多id 需要找到对应的父级id 并根据父级id组合 应该怎么根据父级id将数据组合在一起呢？

)</code>这个还是三级分类有可能搜到的是最后一级 那还要找俩级 怎么去合并啊
只想到用foreach 将相同父id的数据放到同一个以parent_id为key的数组内，如果要父级信息的话还可以进行次逻辑判断
<code>$result =[]
foreach($list as $key => $val){
if($val['parent_id'] != 0) {
$result[$val['parent_id']][] = $val;
}
}
</code>
1、增加一个path字段，表示从根节点到叶子节点的路径比如 1.3.7
要求是搜索 然后找出搜索结果的所有父级和子集 树状图显示 关键字标红
我的做法是
1.创建新数组 用来保存所有需要展示的数据的id 初始数据为查询到的id
2.先根据查询id找到所有父级 放在新数组
3.根据id查询所有子集id 这里可能是多个 我是循环 用array_unshift 放进新数组
4.给新数组的id去重（我这里最终组合的是一个一维数组）
5.循环数组id查询所有数据
6.进行分类组合
