Laravel分组集合返回对象而不是数组

问题描述：

我有以下查询

$outings = Outing::all()->groupBy(function ($item) {
   return Carbon::parse($item['start'])->format('m/d/Y');
});

return response()->json([
    'outings' => $outings
], 200);

响应返回一个对象，我需要它返回一个数组

The response is returning an object and I need it to return an array

如何使郊游成为数组而不是对象.

How can I get outings to be an array instead of an object.

如果我不对集合进行分组，而只是做

If I don't group the collection and just do

Outing::all();

它将返回一个数组而不是一个对象. Group by做的事情很奇怪.

It will return an array rather than an object. The Group by is doing something weird.

如果我DD($ outings)确实返回了一个集合，所以我认为将其返回到浏览器而不是数组时强制转换为对象是很奇怪的.

If I DD($outings) it does in fact return a collection, so I think it's odd that it gets cast to an object when returned to the browser rather than an array.

以下是我DD($ outings-> toArray())

Below is the output when I DD($outings->toArray())

谢谢

答

如果要数组，请使用此

If you want array then use this

$outings = Outing::all()->groupBy(function ($item) {
   return Carbon::parse($item['start'])->format('m/d/Y');
})->map(function($item){
    return $item->all();
});

return response()->json($outings, 200);

如果您希望日期作为键，那么

If you want date as key then

$outings = Outing::all()->groupBy(function ($item) {
   return Carbon::parse($item['start'])->format('m/d/Y');
});

return response()->json($outings->toArray(), 200);
