[{"fupdz":"36","data":[{"id":"37","fup":"36","name":"\u5546\u5bb6\u70b9\u8bc4","px":"4","icon":"a5\/common_37_icon.png"}]},{"fupdz":"36","data":[{"id":"38","fup":"36","name":"\u623f\u5c4b\u79df\u552e","px":"5","icon":"a5\/common_38_icon.png"}]},
如何改成

]
},
的这个形式 前面相同然后合并在一起

唯一方式：遍历重构

循环，然后判断 fupdz 一致则放一起

$query = DB::query("SELECT * FROM " . DB::table('forum_forum') . " WHERE type='group' and status=1 ORDER BY fid ASC"); $ar=array(); while ($soft = DB::fetch($query)) { $querys = DB::query("SELECT * FROM " . DB::table('forum_forum') .

```javascript
const sort = (arr) => { let hash = {} let newArr = [] let i = 0 for (let item of foo) { if (hash[item.fupdz] == undefined) { hash[item.fupdz] = i newArr.push(item) i++ } else { const idx = hash[item.fupdz] const data = item.data data.forEach(item => newArr[idx].data.push(item)) } } return newArr } ``` 这样写应该没问题，楼主试试 |

v2 的回复功能太坑，不支持 markdown 还把代码缩进给吃了....
