php 双重foreach的坑

Question

$cardInfo的JSON格式如下
{
"code":1,
"msg":"success",
"time":1524036614,
"data":{
"list":[
{
"id":1000,

想变换数组结构为
{
"code":1,
"msg":"success",
"time":1524036789,
"data":{
"list":[
{
"shop_id":1,
"shop_name":"测试商家1",
"goodsInfo":[
{goods1},{goods2}
]
},
{
"shop_id":2,
"shop_name":"测试商家2",
"goodsInfo":[
{goods3},{goods4}
]
}
]
}
}
于是有了如下代码
$cartInfo=collection($cartItems)->toArray();
$shops=array_column($cartInfo,'shopInfo','business_id');
$shop_list=[];
$shop_lists=[];
foreach($shopsas$key=>$shop){
foreach($cartInfoas$k=>$item){
if($item['business_id']===$key&&$item['shopInfo']['id']===$key){
$shop_list['shop_id']=$item['business_id'];
$shop_list['shop_name']=$item['shopInfo']['name'];
$shop_list['goodsInfo'][]=$item['goodsInfo'];
}
}
$shop_lists[]=$shop_list;
}
return$shop_lists;
但是出来的结果却是
{
"code":1,
"msg":"success",
"time":1524036931,
"data":{
"list":[
{
"shop_id":1,
"shop_name":"测试商家1",

"delete_time":null,

"sale_price":"60.00",
"host_per":"10.00",
"update_time":0,
"is_delete":0,
"delete_time":null
}
}
]
},
{

}
]
}

}
}
也就是在商家2里面所有商品都进去了。实际上商家1有一个商品，商家2有2个商品求问大佬们这是个什么情况？怎么解决？

Answer 1

$shop_lists=[];foreach($cardInfo['data']['list']as$v){if(empty($shop_lists[$v['business_id']])){$shop_lists[$v['business_id']]['shop_id']=$v['business_id'];$shop_lists[$v['business_id']]['shop_name']=$v['goodsInfo']['name'];}$shop_lists[$v['business_id']]['goodsInfo'][]=$v['goodsInfo'];}$cardInfo['data']['list']=$shop_lists;应该是你想要的答案
