ErrorExceptionarray_merge():期望引數1是一個陣列，給定物件

$absent 變數 的資料結果 $belum_absen 變數的資料結果

我在 App\Reports\ExportReport.php 檔案夾中的代碼

class ReportExport implements FromCollection
{
  $absen = DB::table('attendance as in')
                            ->where('in.in_out', 'in')
                            ->where('in.company_id', \Session::get('selected_company'))
                            ->whereDate('in.created', $date)
                            ->leftJoin('attendance as out', function ($join) use ($date) {
                                $join->on('in.employee_id', 'out.employee_id')
                                    ->where('out.in_out', 'out')
                                    ->where('out.company_id', \Session::get('selected_company'))
                                    ->whereDate('out.created', $date);
                            })
                            ->join('employee', 'employee.id', 'in.employee_id')
                            ->join('location_library', 'location_library.id', 'in.attendance_location_id')
                            ->join('company as cp', 'cp.id', 'in.company_id')
                            ->join('employee_in_app as e_app', 'e_app.employee_id', 'in.employee_id')
                            ->join('employee_in_company', 'in.employee_id', 'employee_in_company.employee_id')
                            ->select('in.id', 'in.employee_id', 'in.attendance_time as in_time', 'out.attendance_time as out_time', 'in.work_hour_start', 'in.late_tolerance', 'employee.*', 'location_library.location_name', 'in.attendance_location_id', 'cp.alias', 'e_app.note', 'in.company_id', 'in.attendance_time', 'employee_in_company.ignore_work_hour', 'employee_in_company.attendance_group_id')
                            ->orderBy('in.attendance_time', 'DESC')
                            ->get();

  $belum_absen = EmployeeInCompany::where('company_id', \Session::get('selected_company'))
                        ->join('company', 'company.id', 'employee_in_company.company_id')
                        ->join('employee', 'employee.id', 'employee_in_company.employee_id')
                        ->whereNotIn('employee.id', $data)
                        ->select('employee.name','company.alias','employee.id')
                        ->orderBy('employee.name', 'asc')
                        ->get();

      $combine = array_merge($absen, $belum_absen);
      return $combine;
}
 

我正在制作匯出 excel，所以我想組合來自變數 $absent 和 $belum_absen 的資料，但是我收到錯誤“array_merge(): Expected parameter 1 to be an array, object given”有沒有辦法解決這個問題問題？幫幫我，謝謝

uj5u.com熱心網友回復：

這些查詢回傳集合，而不是陣列。所以你不能對它們使用陣列函式。Laravel 有非常有用的 Collection 方法。我建議你看看他們。https://laravel.com/docs/9.x/collections

你需要的方法是

return $absen->merge($belum_absen);

您不能使用 array_merge 來合并多個集合。您應該在 get() 之后使用 ->toArray() 將集合資料轉換為陣列。之后你可以使用array_merge。

class ReportExport implements FromCollection

  $absen = DB::table('attendance as in')
                            ->where('in.in_out', 'in')

                            ->whereDate('in.created', $date)
                            ->leftJoin('attendance as out', function ($join) use ($date) {
                                $join->on('in.employee_id', 'out.employee_id')
                                    ->where('out.in_out', 'out')
