php - 如何在laravel中获取所有月份的记录数

Question

我已经应用了 group by with with created_at column using DB query 但喜欢用 laravel eloquent 来做

输出应该是这样的:-

Array
(
  [1] => 2
  [2] => 3
  [3] => 7
  [4] => 4
  [5] => 5
  [6] => 7
  [7] => 2
  [8] => 9
  [9] => 0
  [10] => 4
  [11] => 0
  [12] => 0
)

请提供任何帮助我做到这一点。

请尝试以下步骤:-

1. 运行composer安装包:composer require nesbot/carbon
2. 在您的代码之上:使用 Carbon\Carbon；

假设我有模型用户，

$users = User::select('id', 'created_at')
->get()
->groupBy(function($date) {
    //return Carbon::parse($date->created_at)->format('Y'); // grouping by years
    return Carbon::parse($date->created_at)->format('m'); // grouping by months
});

$usermcount = [];
$userArr = [];

foreach ($users as $key => $value) {
    $usermcount[(int)$key] = count($value);
}

for($i = 1; $i <= 12; $i++){
    if(!empty($usermcount[$i])){
        $userArr[$i] = $usermcount[$i];    
    }else{
        $userArr[$i] = 0;    
    }
}

希望它能帮助你制作这样的数组。
