Answer 1

I assume that your code of foreach is correct you can try this modified header code
$filename=mt_rand(1,100000).'.xls'; //just some random filename
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header("Content-Disposition: attachment; filename='".$filename."'");
header("Pragma: public");
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); //downloadable file is in Excel 2003 format (.xls)
$objWriter->save('php://output'); //send it to user, of course you can save it to disk also!
exit;
Or You can also try Below code that is working for me in my project
$objPHPExcel->setActiveSheetIndex(0);
// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="Booking Report.xlsx"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
