download file then redirect to another page

Question

I need to download an apk application but I need to keep the user in my page or redirect him to another page with header I can only download the application or redirect him to another page, but I can't do both at the same time my php code :

    $b= "location"; 



    echo "<script>window.location.href = '$b';</script>" ; 

            $file = 'apk.apk';

if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);

}

According to my research for 5 minutes. what you are requesting is impossible.

Take as an example a page that downloads something then redirects to "thank you for downloading"

The way they actually do it is they take you to the "thank you" page, and then they start the download.

To implement this in your code, you'd need to open up $b location first, and in that script you start the download by redirecting to a PHP script that contains the downloading.

Example:

download.php

$file = 'apk.apk';

if (file_exists($file))
{
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.basename($file).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    readfile($file);
}

hello.php

$b= "download.php"; 
echo "Hello! <script>window.location.href = '$b';</script>" ;

When you visit hello.php you will see Hello! and the download will start

I tried to do that but it download the application then exit the page without calling the javascript code — Rami Osman, Mar 01 '16 at 11:46

@aron9forever thanks for your help, I found a good way to do that :

$e= "url.com" ; 



echo "<script>setTimeout(function(){window.location.href = '$e';} ,2)</script>" ; 


echo "<iframe src='download.php' ></iframe>" ;

and the download.php :

<?php
$file = 'apk1.apk';

if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);

}
?>

download file then redirect to another page
