我有以下数组,我希望能够通过集合
组织它$collection = Collection($total);
$filter = $collection->groupBy('date_general')->toArray();
[2017-11-14] => Array
(
[0] => Array
(
[status] => pending
[date_general] => 2017-11-14
[user_id] => 164
)
[1] => Array
(
[status] => pending
[date_general] => 2017-11-14
[user_id] => 112
)
)
到目前为止,我已经按日期组织了数组。现在我需要在每个日期内按用户组织它,也就是说它是:
[2017-11-14] => Array
(
[164] => Array
(
[0] => Array
(
[status] => pending
[date_general] => 2017-11-14
[user_id] => 164
)
)
[112] => Array
(
[0] => Array
(
[status] => pending
[date_general] => 2017-11-14
[user_id] => 112
)
)
)
答案 0 :(得分:4)
您必须处理每个日期组并单独分组其内容。
$collection = collection($total)
->groupBy('date_general')
->map(function ($data) {
return collection($data)->groupBy('user_id')->toArray();
});
