PHPExcel 导出不起作用：显示“无法访问该网站”

我已经从服务器克隆了一个项目并安装在我的本地设置中。 我正在尝试使用 PHPExcel 将 Excel 文件导出到浏览器。它在服务器中运行良好。但是本地设置有问题。 我还检查了列和字段的数量，它们都很好。 下面是代码：

<?php
//PHPExcel starts from here
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Asia/Kathmandu');

if (PHP_SAPI == 'cli')
    die('Error in loading PHPExcel');


// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Set document properties
$objPHPExcel->getProperties()->setCreator("GBD Admin")
        ->setLastModifiedBy("GBD Admin")
        ->setTitle("Weekly checkin/checkout log")
        ->setDescription("Test document for PHPExcel, generated using PHP classes.")
        ->setKeywords("Checkin/Checkout Logs")
        ->setCategory("Checkin/Checkout Logs");


// Add some data
$objPHPExcel->setActiveSheetIndex(0)
        ->setCellValue('A1', 'Date of Export')
        ->setCellValue('B1', $now)
        ->setCellValue('A3', 'Employee Name')
        ->setCellValue('B3', ' Checkin-date')
        ->setCellValue('C3', ' Checkin-time')
        ->setCellValue('D3', ' Checkout-date')
        ->setCellValue('E3', ' Checkout-time')
        //                        ->setCellValue('F3', ' Total-time Spent')
        //                        ->setCellValue('G3', ' Over-time')
        ->setCellValue('F3', ' Early checkout-remarks')
        ->setCellValue('G3', ' Late checkin-remarks');

//                        Newly added statement below
//                        ->setCellValue('H3', ' Absent/Leave Remarks');
$objPHPExcel->getActiveSheet()->getStyle('A1:B1')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->getStyle('A3:H3')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->fromArray($results, null, 'A5');
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(45);
$objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(45);

// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Login-data-' . $now);


// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);


// Redirect output to a client’s web browser (Excel5)
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="Login_data_' . $now . '.xls"');
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('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header('Pragma: public'); // HTTP/1.0

$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
?>

我一直收到这个错误：

无法访问该网站

网页位于http://localhost/gbdportal-new/导出 http://localhost/gbdportal-new/Export可能 暂时关闭或者可能已永久移动到新网站 地址。 ERR_INVALID_RESPONSE

它与当前在服务器上运行的实时版本运行良好。可能是什么问题呢？

这是 phpExcel 与 php7 结合的一个 bug：
