Using PHPExcel to export to xlsx - php

Question

I am using PHPEXxcel to export an HTML Table generated using MYSQL and its like this.
<?php $query = "SELECT `Firstname`,`Lastname`,`Branch`,`Gender`,`Mobileno`, `Email`
FROM `student_details` WHERE Branch IN ('$branch') and `Year`='$year'
and Tenthresult > '$tenth' and
Twelthresult > '$twelth' and (CGPA > '$cgpa' || CGPA = '$cgpa')";
$result = mysql_query($query);
confirm_query($result);
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$rowCount = 1;
$objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount,'Firstname');
$objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount,'Lastname');
$objPHPExcel->getActiveSheet()->SetCellValue('C'.$rowCount,'Branch');
$objPHPExcel->getActiveSheet()->SetCellValue('D'.$rowCount,'Gender');
$objPHPExcel->getActiveSheet()->SetCellValue('E'.$rowCount,'Mobileno');
$objPHPExcel->getActiveSheet()->SetCellValue('F'.$rowCount,'Email');
while($row = mysql_fetch_array($result)){
$rowCount++;
$objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $row['0']);
$objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $row['1']);
$objPHPExcel->getActiveSheet()->SetCellValue('C'.$rowCount, $row['2']);
$objPHPExcel->getActiveSheet()->SetCellValue('D'.$rowCount, $row['3']);
$objPHPExcel->getActiveSheet()->SetCellValue('E'.$rowCount, $row['4']);
$objPHPExcel->getActiveSheet()->SetCellValue('F'.$rowCount, $row['5']);
}
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save('some_excel_file.xlsx');
?>
Its working but it saves the xlsx file in the root folder without showing to user any signs that its being downloaded.
This code rund when i click a button.now, can i make it to be downloaded like we download a mail attachment and showing the user in the front end that its being downloaded along with the location.
I tried using
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="01simple.xls"');
header('Cache-Control: max-age=0');
With this, i am getting what i wanted above but the xls file downloaded when opened shows
the message
'The File you are trying to open 'filename' is in a different format than the specified extension.....etc.Do you want to open now?
On opening it contains either the entire HTML Page or its simply blank...
Can anybody help me..?

Spreadsheets 101
There are many different spreadsheet file formats, each with their own different filename extensions, and that can be sent to a web browser using different mime types. These are described in the PHPExcel documentation, and each has its own different Writer in PHPExcel. You're mismatching two different formats
BIFF Format
Used by Microsoft Excel between versions 95 and 2003 File
extension: xls
PHPEXcel Writer: PHPExcel_Writer_Excel5
Mime Type: application/vnd.ms-excel
OfficeOpenXML Format
Used by Microsoft Excel since version 2007
File extension: xlsx
PHPEXcel Writer: PHPExcel_Writer_Excel2007
Mime Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
Don't mix and match: if you do, then Excel will (and justifiably) complain. If you want a BIFF file, use PHPExcel's BIFF Writer (Excel5), a file extension of .xls, and the mime type listed above for BIFF Format. If you want an OfficeOpenXML file, then use PHPExcel's Excel2007 Writer, a file extension of .xlsx, and the mime type listed above for OfficeOpenXML.
EDIT
Note that the examples provided with the PHPExcel distribution include 01simple-download-xls.php and 01simple-download-xlsx.php to demonstrate exactly what you want

Just adding those headers only sends those headers. The rest of your code is still the same, so you're saving your xls to your root folder like you used to.
Sending the headers only makes the page you would normally see be send with xls headers. Something which is not what you want, and you're getting your HTML page but with the wrong headers.
What you need to do is send those headers and then stream the xlsx.
Looking at a random thread (I know, bad idea, but this'll get you a headstart on what to do) here, you can find examples like this:
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=$filename.xls");
header("Content-Transfer-Encoding: binary ");
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->setOffice2003Compatibility(true);
$objWriter->save('php://output');

I do it with using below snippet.
// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="test_file.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');

try this ..
header('Content-Type: application/vnd.ms-excel');
$filename = "Reports".date("d-m-Y-His").".xls";
header('Content-Disposition: attachment;filename='.$filename .' ');
header('Cache-Control: max-age=0');
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
