這個還是三級分類有可能搜到的是最後一級 那還要找兩個等級 怎麼去合併啊
只想到用foreach 將相同父id的資料放到同一個以parent_id為key的數組內，如果要父級資訊的話還可以進行次邏輯判斷
<code>$result =[]
foreach($list as $key => $val){
if($val['parent_id'] != 0) {
$result[$val['parent_id']][] = $val;
}
}
</code>
1、增加一個path字段，表示從根節點到葉子節點的路徑例如 1.3.7
要求是搜尋 然後找出搜尋結果的所有父級和子集 樹狀圖顯示 關鍵字標紅
我的做法是
1.創建新數組用來保存所有需要展示的數據的id 初始數據為查詢到的id
2.先根據查詢id找到所有父級放在新數組
3.根據id查詢所有子集id 這裡可能是多個我是循環用array_unshift 放進新數組
4.給新數組的id去重（我這裡最終組合的是一個一維數組）
5.循環數組id查詢所有數據
6 .進行分類組合
感謝回答的朋友 有更好的辦法請分享出來 哈哈
