laravel - 计数相同值 Laravel 集合

Question

我想在 laravel 集合中计算相同的值，这是我的数组：

[
 'January' => [
  [
   'status' => 'active',
  ], [
   'status' => 'active',
  ], [
   'status' => 'disable',
  ], [
   'status' => 'active',
  ], 

  'February' => [
   'status' => 'active',
  ], [
   'status' => 'active',
  ], [
   'status' => 'disable',
  ], [
   'status' => 'disable',
  ], 
 ]

我想计算相同的值是这样的：

[
 'January' => [
  'active' => 3
  'disable' => 1,
 ], 

 'February' => [
  'active' => 2,
  'disable' => 2,
 ]

如何做到这一点使用 laravel 集合？

您可以使用 Collection'smap并countBy执行此操作：

collect($array)->map(fn ($i) => collect($i)->countBy('status'));
