使用循环生成多个PDF文档

以下是我的 Laravel 控制器之一中的一些代码，用于生成多个时间表 PDF。它只创建 1 个，我确信这是由于 return 语句造成的，但我如何让它创建所有 PDF？我正在使用 barryvdh/laravel-dompdf。

public function alltimesheets(Request $request)
    {
        $weeks = Timesheet::where('week_ending', $request->week_ending)->get();
        $week_ending = Carbon::parse($request->week_ending)->format('d-m-Y');
        foreach($weeks as $hours)
        {

            $pdf = PDF::loadView('pdf.timesheet', compact('hours', 'week_ending'));
            $sheet = $pdf->setPaper('a4', 'landscape');
            return $sheet->download($hours->user->name.' - '.$week_ending.'.pdf');
        }
    }

首先将所有视图 html 放入一个变量中，然后将其传递给 PDF。

尝试以下代码：

public function alltimesheets(Request $request)
{
    $weeks = Timesheet::where('week_ending', $request->week_ending)->get();
    $week_ending = Carbon::parse($request->week_ending)->format('d-m-Y');
    $html = '';
    foreach($weeks as $hours)
    {
        $view = view('pdf.timesheet')->with(compact('hours', 'week_ending'));
        $html .= $view->render();
    }
    $pdf = PDF::loadHTML($html);            
    $sheet = $pdf->setPaper('a4', 'landscape');
    return $sheet->download('download.pdf');  // $hours can not be accessed outside foreach. So changed the file name to `download.pdf`.
}
