比如下面是我从数据库中读取出来的数据,然后我想以suppliers_id为基准重新排列这个数组,有什么比较好的方法?
<code>[ { cart_id: "6", suppliers_id: "1", goods_name: "商品1", }, { cart_id: "7", suppliers_id: "1", goods_name: "商品2", } { cart_id: "7", suppliers_id: "1", goods_name: "商品3", } ]</code>
变成
<code>[ //suppliers_id 1: [ { cart_id: "6", suppliers_id: "1", goods_name: "商品1", }, { cart_id: "7", suppliers_id: "1", goods_name: "商品3", } ] //suppliers_id 2: [ { cart_id: "7", suppliers_id: "1", goods_name: "商品2", } ] ]</code>

看到标签是 php
表示无能为力。
如果是在前端处理你倒是可以用 sort(function(a,b){})
这种思路来。
使用PHP的uksort函数,这货可以接收两个参数
<code>$arr = [ {c:"213"} , {c:"dadad"}] function compare_func($a, $b){ return $a=>c - $b=>c; } uksrot($arr,"compare_func" );</code>
