PHPExcel export not working : displays "the website cannot be reached" - php

Question

I have cloned a project from server and installed in my local setup.
I am trying to export excel file to the browser using PHPExcel. It is working fine in the server. But there is problem with the local setup.
Also I checked number of columns and fields and they are fine.
Below is the code:
<?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('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, 'Excel5');
$objWriter->save('php://output');
exit;
?>
I have been getting this error:
This site can’t be reached
The webpage at http://localhost/gbdportal-new/Export might be
temporarily down or it may have moved permanently to a new web
address. ERR_INVALID_RESPONSE
It is working fine with the live version currently running on the server. What could be the problem?

This is a bug in phpExcel in combination with php7:
