Export data to pdf in Laravel downloading only 2 pages irrespective of data

I have huge amount of data in my DB. But when I try to export data to pdf in Laravel only 2 pages are downloading.

public function pdfview(Request $request) {

     $members = DB::table('members')->where('id_card_issued',0)->get();
     $pdf = PDF::loadView('admin.myPDF', compact('members'));
     return $pdf->download('id_card.pdf');
    }

I want all the data to be downloaded. But now only getting last 2 data in my database table
