如何根据键名条件从集合中获取价值？

Question

我正在尝试从 PHP 中的集合中获取值。

$todaylog 变量包含来自 laravel 查询构建器的集合：

   $todaylog = [
   {
      "row_id":55,
      "emp_number":"IPPH0004",
      "timestamp":"03:30:23",
      "attendance_status":"Punch In",
      "date_created":"2021-10-01"
   },
   {
      "row_id":56,
      "emp_number":"IPPH0004",
      "timestamp":"11:32:50",
      "attendance_status":"Start Break",
      "date_created":"2021-10-01"
   },
   {
      "row_id":57,
      "emp_number":"IPPH0004",
      "timestamp":"11:33:09",
      "attendance_status":"End Break",
      "date_created":"2021-10-01"
   }
   ]

到目前为止我做了什么：但是这种方法太慢了：

$timein = DB::table('attendance')->select('timestamp')->where('attendance_status','Punch In')->get();

现在我想要这样的东西：（PS这只是一个伪代码）

$timein = (where) $todaylog.attendance_status = "Punch In"
$endbreak = (where) $todaylog.attendance_status = "End Break"

这可能吗？或者我必须将它们单独查询到数据库？谢谢

Answer 1

可以使用laravel集合where方法：

collect($todaylog)->where("attendance_status", "Punch In")->first();

Answer 2

Laravel 你需要的是这样的东西：

$rows = collect([
       [
           "row_id" => 55,
          "emp_number" => "IPPH0004",
          "timestamp" => "03:30:23",
          "attendance_status" => "Punch In",
          "date_created" => "2021-10-01"
       ],
       [
           "row_id" => 56,
          "emp_number" => "IPPH0004",
          "timestamp" => "11:32:50",
          "attendance_status" => "Start Break",
          "date_created" => "2021-10-01"
       ],
        [
           "row_id" => 57,
          "emp_number" => "IPPH0004",
          "timestamp" => "11:33:09",
          "attendance_status" => "End Break",
          "date_created" => "2021-10-01"
       ]]);

    dd($rows->where('row_id', 57));

结果：

Illuminate\Support\Collection {#446 ▼
  #items: array:1 [▼
    2 => array:5 [▼
      "row_id" => 57
      "emp_number" => "IPPH0004"
      "timestamp" => "11:33:09"
      "attendance_status" => "End Break"
      "date_created" => "2021-10-01"
    ]
  ]
}
