PHP xlsx header
Solution 1
Depends on your browsers so many things can cause such behavior such as Content-length
, Cache-Control
etc
Also Change
Content-type
to Content-Type
Content-disposition
to Content-Disposition
Try
$file = "myfile.xlsx" ;
header('Content-Disposition: attachment; filename=' . $file );
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Length: ' . filesize($file));
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate');
header('Pragma: public');
readfile('myfile.xlsx');
Solution 2
Depending on your web browser, the filename may not be saving fully with periods. If the filename is incomplete, you can try and replace this header:
header('Content-disposition: attachment; filename=myfile.xlsx');
with
$filename = "myfile.xlsx";
header('Content-Disposition: attachment; filename="' . $filename . '"');
Solution 3
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save($filename);
header('Content-Disposition: attachment; filename="' . $filename . '"');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Length: ' . filesize($filename));
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate');
header('Pragma: public');
readfile($filename);
return;
This solution works for me, but when i'm trying to open downloaded file i'm getting an error. For .pdf file is just empty.

GTCrais almost 3 years
so this works:
myphpfile.php:
<?php header('Content-disposition: attachment; filename=myfile.pdf'); header('Content-type: application/pdf'); readfile('myfile.pdf'); ?>
that php file is called here and the PDF download works fine:
<a class = "oglasavanje" href = "../../cjenik/myphpfile.php">download</a><br/>
but this doesn't work:
<?php header('Content-disposition: attachment; filename=myfile.xlsx'); header('Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); readfile('myfile.xlsx'); ?>
both .pdf and .xlsx files are in the same folder. When I click on the 'download' link the download windows pops up, I save the file, but the file can't be opened. It gives me the following error:
Excel cannot open the file 'myfile.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
The file opens fine when I open it manually (i.e. without downloading it via the link)
I'm using WAMP, if that's of importance.
Any help is appreciated.
--- EDIT ---
I've found this piece of code on php.net:
ob_clean(); flush();
so the final code looks like this and it works:
$file = "myfile.xlsx"; header('Content-disposition: attachment; filename='.$file); header('Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Length: ' . filesize($file)); header('Content-Transfer-Encoding: binary'); header('Cache-Control: must-revalidate'); header('Pragma: public'); ob_clean(); flush(); readfile($file);
Thanks everyone for the answers.

Marcus Vinicius Pompeu almost 3 yearsCan you explain why your solution is better than the accepted one, from six years ago? And could you ident the code?
