Using PHP_XLSXWriter, if I write an .xlsx file to the server, download and then open it in Excel all works well :-
include_once("xlsxwriter.class.php");
$filename = "example.xlsx";
$rows = array(
array('year','month','amount'),
array('2003','1','220'),
array('2003','2','153.5'),
);
$writer = new XLSXWriter();
$writer->writeSheet($rows);
$writer->writeToFile("/path/to/file/$filename");
However if I output the file direct from the browser, opening the downloded file gives me the error message "Excel cannot open the file 'example.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."
include_once("xlsxwriter.class.php");
$filename = "example.xlsx";
header('Content-disposition: attachment; filename="'.XLSXWriter::sanitize_filename($filename).'"');
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header('Content-Transfer-Encoding: base64');
header('Cache-Control: must-revalidate');
header('Pragma: public');
$rows = array(
array('year','month','amount'),
array('2003','1','220'),
array('2003','2','153.5'),
);
$writer = new XLSXWriter();
$writer->writeSheet($rows);
$writer->writeToStdOut();
This is running on a Ubuntu 20 server running Apache2 and PHP 7.2
Any ideas what is going wrong?
Many thanks
I found the problem....I had a single space outside the tags in the xlsxwriter.class.php file. Infuriating.

I'm trying to download a .rar file from a cloud (for sake of simplicity I'm using my google drive storage), the file is downloading perfectly, but once i want to open the .rar file , it says that "the archive is either unknown format or damaged" , tried all methods even cURL ,but it didnt want to work,
Im just wondering what I'm missing in my code, thank you
<?php
$filename = 'stu.rar';
if ( file_put_contents( $filename,file_get_contents("mygoogleDriveLink/search?q=stu.rar"))) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$filename.'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
//header('Content-Length: '.filesize($filename));
readfile($filename);
//print_r("this is ".$id);
exit();
}
else{
echo "err";
}
You may use file_put_contents to save the file to the server first, before you stream it to your browser.
if you do not need to stream to user's web browser, then you may remove the codes from start streaming to end streaming.
Please try the following:
<?php
// Initialize a file URL to the variable
$url = 'http://www.xxxxxxxxxxx.com/xxxxx.rar';
// Use basename() function to return the base name of file
$file_name = basename($url);
// Use file_get_contents() function to get the file
// from url and use file_put_contents() function to
// save the file by using base name
if(file_put_contents( $file_name,file_get_contents($url))) {
// File successfully saved in the server
// start streaming . The following is to stream and save to browser
$file_name = $file_name;
$file_url = $file_name;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
exit;
/// end streaming
}
else {
echo "File downloading failed.";
}
?>
I am having issues opening exported excel file.
I was having the same issue earlier and I had to store it to some path first, and then read the file and write it to the output buffer.
That worked with no issues on my local machine.
But the same issue occurred in the server.
Here's what I did earlier:
// Save Excel 2007 file
$lsFileName = isset($file_name) && $file_name != null ? $file_name.'.xlsx' : 'Report.xlsx';
$upload_dir = "upload/export_dump/";
if(is_dir($upload_dir) == false) {
mkdir($upload_dir, 0777);
}
$lsSavePath = $upload_dir.$lsFileName;
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->setIncludeCharts(TRUE);
$objWriter->save($lsSavePath);
$lnFilesize = filesize($lsSavePath);
// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/force-download');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header("Content-Disposition: attachment; filename=" . utf8_decode($lsFileName));
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
header('Cache-Control: max-age=0');
header("Content-Length:" . $lnFilesize);
readfile($lsSavePath);
EDIT: I tried checking if any outputs are made prior to reading file.
.
.
header("Content-Length:" . $lnFilesize);
$output = ob_get_contents();
if(!empty($output)) {
var_dump($output);
die('Something was definitely printed!');
} else {
readfile($lsSavePath);
}
But the file gets downloaded, and the same repair message pops up.
NOTE: On downloading the file from the server itself (not through browser) and opening the file, there is no issue.
everybody, im running in some issue right now, see for internal situations with the server that i cant control or anything right now i cant use base64 encoded files directly over the website cause when the server delivers content to the browser it has a limit of characters for those tasks and it directly affects base64 encoded files cause of the lenght of those strings, so i made for one system a php script that delivers an already existing base64 pdf files to the client as a downloadable file, and it worked just like this:
$reg = File::find($args->string('id')); //querying the file from database
$filename = $reg->filename; //the original file name
$base64 = $reg->file; //the base64 encoded file
$meta_type = explode(',', $base64) [0]; //getting the meta type of the file
$meta_type = str_replace('data:', '', $meta_type);
$meta_type = str_replace(';base64', '', $meta_type);
$file = explode(',', $base64) [1];
$file = base64_decode($base64); //decoding the base64 string
header('Content-Description: File Transfer');
header('Content-Type: ' . $meta_type);
header('Content-Disposition: attachment; filename="' . $filename . '"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . (strlen($file)));
echo $file;
this worked just fine when i use pdf files but when i try to use it on some 'xlsx' files it seem to work, it download the file, the filesize and all seem to match the original, but excel cant open the file, does anybody have an idea of what im i missing here?? :)
I am pretty sure, its happening, because you are not exiting your function and it continues to fill up buffers. You have to stop the script immediatelly after your stream is ready, clean the buffer and exit.
If its a valid Excel file, all you have to do is:
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Cache-Control: must-revalidate');
header('Expires: 0');
header('Pragma: public');
header('Content-Disposition: attachment; filename="' . $filename . '"');
if (ob_get_contents() || ob_get_length()) {
ob_end_clean(); //or ob_end_flush();
}
exit();
I am working on a project where I get a file stream and write this file to the servers local disk.
I then want PHP to download it but instead it just dumps out the data of the file to the page.
Below is how I am writing the file and trying to tell PHP to download it
$settingsManager = new SettingsManager();
$this->tempWriteLocation = $settingsManager->getSpecificSetting("hddFileWriterLocation");
$downloadUrl = $settingsManager->getSpecificSetting("tempFileUrlDownload") . "/$this->tempFileName";
if (!$this->checkIfDirectoryExists())
{
throw new Exception("Failed to create temp write directory: $this->tempWriteLocation");
}
$filePathAndName = "$this->tempWriteLocation\\$this->tempFileName";
$fh = fopen($filePathAndName, "w");
if (!$fh)
{
throw new Exception("Failed to open file handle for: $filePathAndName. " . error_get_last());
}
fwrite($fh, $this->fileData);
fclose($fh);
//return $downloadUrl;
header('Content-Description: File Transfer');
header('Content-Type: audio/wav');
header('Content-Disposition: attachment; filename='.basename($filePathAndName));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($filePathAndName));
ob_clean();
flush();
readfile($filePathAndName);
When the above code being run, I get the following output (only a snippet)
RIFF\tWAVELIST2INFOISFT%Aculab Media System Server V2.3.4b11fmt
##fact�sdata�sUU������UUUUUU�UUU��U���UU��UUU�UUUU���UU���UU�����UU
Just so you know the diamonds are actual output I get back, not anything wrong with Stack Overflow displaying something properly.
I've tried setting the content-type to be force-download but doesn't make any difference.
Try this header:
header('Content-type: audio/x-wav', true);
header('Content-Disposition: attachment;filename=wav-filename.wav');
and see if this works. From what I see you have you code formation setup correctly. Fixing the headers should download the file automatically.
I'm trying to use PHPWord to generate word documents. And the document can be generated successfully. But there is a problem where my generated word document will be saved on the server. How can I make it available to download straight away?
Sample:
$PHPWord = new PHPWord();
//Searching for values to replace
$document = $PHPWord->loadTemplate('doc/Temp1.docx');
$document->setValue('Name', $Name);
$document->setValue('No', $No);
$document->save('php://output'); //it auto save into my 'doc' directory.
How can i link to the header to download it as follows:
header("Content-Disposition: attachment; filename='php://output'"); //not sure how to link this filename to the php://output..
Kindly advise.
php://output is a write-only stream, that writes to your screen (like echo).
So, $document->save('php://output'); will not save the file anywhere on the server, it will just echo it out.
Seems, $document->save, doesn't support stream wrappers, so it literally made a file called "php://output". Try using another file name (I suggest a temp file, as you just want to echo it out).
$temp_file = tempnam(sys_get_temp_dir(), 'PHPWord');
$document->save($temp_file);
In the header, the filename field is what PHP tells the browser the file is named, it doesn't have to be a name of a file on the server. It's just the name the browser will save it as.
header("Content-Disposition: attachment; filename='myFile.docx'");
So, putting it all together:
$PHPWord = new PHPWord();
//Searching for values to replace
$document = $PHPWord->loadTemplate('doc/Temp1.docx');
$document->setValue('Name', $Name);
$document->setValue('No', $No);
// // save as a random file in temp file
$temp_file = tempnam(sys_get_temp_dir(), 'PHPWord');
$document->save($temp_file);
// Your browser will name the file "myFile.docx"
// regardless of what it's named on the server
header("Content-Disposition: attachment; filename='myFile.docx'");
readfile($temp_file); // or echo file_get_contents($temp_file);
unlink($temp_file); // remove temp file
$objWriter = PHPWord_IOFactory::createWriter($PHPWord, 'Word2007');
$filename = 'MyFile.docx';
$objWriter->save($filename);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($filename));
flush();
readfile($filename);
unlink($filename); // deletes the temporary file
exit;
This is work for me:
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007', $download = true);
header("Content-Disposition: attachment; filename='File.docx'");
$objWriter->save("php://output");
now whit Ver 0.13.0
https://github.com/PHPOffice/PHPWord
<?
require_once "../include/PHPWord-develop/bootstrap.php";
$templateProcessor = new \PhpOffice\PhpWord\TemplateProcessor('template.docx');
$templateProcessor->setValue('var01', 'Sun');
$templateProcessor->setValue('var02', 'Mercury');
//#####################################################
// Save File
//#####################################################
//#####################################################
header("Content-Disposition: attachment; filename='output01.docx'");
$templateProcessor->saveAs('php://output');

A simple solution for Laravel based on #user3214824 answer.
// ...
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($PHPWord, 'Word2007');
$doc_name = 'fileName.docx';
$objWriter->save($doc_name); // saving in the public path just for testing
return response()->download(public_path($doc_name))->deleteFileAfterSend(true);
Sorry this came in later. I stumbled on this while trying to solve the same problem. I was able to get it working on Laravel 5 using below:
$file_dir = $template_upload_dir.DIRECTORY_SEPARATOR.'filename.docx';
$tags = array();
if (file_exists($file_dir)) {
$templateProcessor = new TemplateProcessor($file_dir);
$tags = $templateProcessor->getVariables();
$replace = array('');
$templateProcessor->setValue($tags, $replace);
$save_file_name = $fullname.'-'.$inv_code.'-'.date('YmdHis').'.docx';
$templateProcessor->saveAs($save_file_name);
return response()->download($save_file_name)->deleteFileAfterSend(true);
}
Hope it helps someone!!!
// Save File
$objWriter = PHPWord_IOFactory::createWriter($PHPWord, 'Word2007');
header("Content-Disposition: attachment; filename='myFile.docx'");
$objWriter->save("php://output");
