I am using below php to open pdf, it is working in Windows browser (eg. Windows Google Chrome), but failure to open by Mobile App (eg: Android Google Chrome), it will be download instead of open.
<?php
$com_no = $_POST['comno'];
$date = $_POST["date"];
$name_of_doc = $_POST["name_of_doc"];
// Store the file name into variable
$file = $com_no.'.pdf';
$filename = $date."_".$name_of_doc;
// Header content type
header('Content-type: application/pdf');
header('Content-disposition: inline; filename="'.$filename.'.pdf"');
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
// Read the file
#readfile($file);
?>
How shoule I rewrite it to support both open in the Windows and Mobile ?
Thank you very much !
TLDR: you can't program it as it is a browser configuration
If your PDF is opened in your desktop browser you have a configuration in your desktop-browser how to handle files of this type.
By default your browser should ask you what to do with data of that mime type.
You get the option:
open with browser
open with other application
store file
and maybe an option
[ ] always perform this action for files of this type
once you checked the option you no longer get bothered.
BTW:
even if you select open in browser, the file is downloaded in a temp folder to get shown.

I have these PHP headers that will force a download (Intranet site) that works on Chrome without prompting the popup, but I cannot avoid the popup warning in Internet Explorer 11 (Version 11.657.18362.0) on Windows 10.
I've tried adding to IE "intranet" site and "internet" site the internal server address this would run from (http://[server]), lower the security levels to the lowest settings for this zone under "intranet" and also "internet". Close and open Internet Explorer and it still has the popup warning.
Here is my PHP code below:
if ($_REQUEST['c']){
$num = $_REQUEST['c'];
$cmd = "test.exe $num";
$ctype ="application/octet-stream";
ob_end_clean();
header('Content-Description: File Transfer');
header('Content-Type:' . $ctype);
header('Content-Disposition: attachment; filename="test.bat"');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: no-cache, must-revalidate');
header('Pragma: public');
header('Content-Length: ' . strlen($cmd));
echo($cmd);
exit;
}
Additionally, once the bat file has downloaded, there is a separate AutoIt script on the user's computer that will scan the download folder for this specific file and will automatically run the file and delete it without the user having to do anything. The idea is to limit the user's clicking to just one time.
This is the popup that I get from IE when I click to download the bat file below:
Any ideas what's wrong or other suggestions around this?
I'm able to reproduce the problem, but it seems that IE browser will keep display this prompt when downloading the bat file for security reason, and we can't disable it.
As a workaround, I suggest you could convert the bat file to a ZIP file, and then download it. Here are some related threads about how to Zip files using JavaScript, you could check them:

I have an Issable (Asterisk based VoIP solution) in my company. I am developing an application in PHP which part of it I need to play the recorded calls. the application is located in a separate server from the Issabel. I already have access to the sound file path which for example is:
/var/spool/asterisk/monitor/2018/10/20/rg-600-2122238507-20181020-223323-1540062203.100880.wav
When I want to play this file using HTML's audio tag by adding the ip address of the issabel server at the beginning of this path, nothing happens and even the Isaabel blocks my IP address since the server is password protected. Any solution to play the file located in this path from my PHP application would be appreciated.
As FélixGagnon-Grenier mentioned the solution to this problem is solved by streaming the audio to the application. I have created stream.php in the server containing the following code:
<?php
$filePath = $_GET['file'];
$fileName = basename($filePath);
$fp=fopen($filePath, "rb");
header("Content-type: application/octet-stream");
header('Content-disposition: attachment; filename=$fileName');
header("Content-transfer-encoding: binary");
header("Content-length: ".filesize($filePath)." ");
fpassthru($fp);
fclose($fp);
and in my application which is located in another server I used HTML5 audio tag to call the file and send the path to the audio file with GET method:
<audio controls>
<source src="https://<SERVER_IP>/stream.php?file='.$callRecordPath.'" type="audio/wav">
Your browser does not support the audio element.
</audio>
and it worked for me!
Thanks
We are trying to force download an .apk file when users reach our website using the below script
$path = "../../".$_GET['file'];
header("Content-Description: File Transfer");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=".$_GET['file'] );
#readfile($path);
Whenever we reach the site and download starts, the following error of "This file can harm your device pops out" in android chrome only. But the same file, when we try to download it by typing in url address bar, it downloads without any warning message.
Any solutions to this. Thanks in advance.
I have a PHP script that is currently working locally that I'd like to put on a server.
Currently, the user choose a .txt file, the PHP script works on it and outputs a new file based on what it read in the file.
The problem is that I can only select files in the folder with the script, and not elsewhere.
I use a to get the file name, but it only gives out the name of the file, and not it's absolute path.
From what I've read, I think that I need to upload the file to the server, process it with the script and then give it back to the user.
I'm not sure this is the correct method though.
Also, while I have found plenty of informations on uploading files to the server, I don't know how to put the new file created by the script in the folder where the original file is located.
You cannot read or write files directly on the client's machine. The client will need to upload the file by selecting it in the browser, the server receives the data, processes the data and returns data. This returned data can be presented in the form of a file download by setting the appropriate HTTP headers. The client will have to acknowledge the file download and save it somewhere of his choosing.
Your server has no business knowing anything about files or folders on the client's machine. It can only communicate with it over the HTTP protocol and send and receive data.
You will have to give the file back to the client, as a downloadable file. You can "write" it to the user by setting some headers. Take a look:
<?php
$file = 'random_text_file.txt';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
}
?>
That will prompt a download of the file to the user.
I want to give to the users of a PHP intranet the possibility to open/save PDF files, which are located in a folder on the Apache server. The PDFs have company private information, so I don't want to put them in a web folder.
echo '<form name="openpdf" method="POST" action="downloadPDF.php">';
echo '<input type="hidden" name="pdf">';
echo'</form>';
<tr>
<td> PDFFile1 </td>
<td></td></tr>
downloadPDF.php:
<?
$pdf=$_POST["pdf"];
if (file_exists($pdf)) {
header('Content-Description: File Transfer');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename='.basename($pdf));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($pdf));
ob_clean();
flush();
readfile($pdf);
exit;
}
?>
The problem is when the user open/save a file, the path is pointing for that folder but in the client PC and not at the server.
If you process the PDFs internally on the server from PHP, you should omit the file:/// from the URL.
So it should be
$pdf="c:/pdfs/example.pdf";
The server does not know the client PC, so readfile does not work here.
You might want to try with a redirect, but I must admit I have no clue if browsers allow that for security reasons (you're switching protocols with the redirect).
What at the moment you are doing is that
Javascript is putting a value of c:\pdfs\example.pdf in the pdf field of your form on click and submitting it to downloadpdf.php.
On server, Downloadpdf.php is assigning $_POST["pdf"] value to $pdf.
If file $pdf exists, it is simply proceeding to offer user to download this file.
Now, this may work where server & client is same computer(specifically on a PC, because of C: drive); i.e. like on Local XAMPP. But on real world, where user and server will be on totally different computers, the if (file_exists($pdf)) is always going to fail(unless On server's C: actually there is a file exaple.pdf in folder pdfs)
In real world, step 3 will fail, because $pdf = c:\pdfs\example.pdf and server will look into its own C: drive (if it is a windows server).
You should
1 Try to upload file with an HTML File Upload Box.
2 Get/fetch it on server using $_FILES and do processing
3. Send required headers for downloading.
