How can JavaScript be used in conjunction with PHP to redirect after a file download?

When a file is downloaded using PHP, the browser stays on the same page after the download is completed. To redirect to a different page after the file download, JavaScript can be used in conjunction with PHP. This can be achieved by sending a JavaScript redirect script along with the file download response from the PHP script. 

<?php
$file = 'path/to/file.pdf';
header('Content-Description: File Transfer');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename=' . basename($file));
header('Content-Length: ' . filesize($file));
readfile($file);

echo '<script>window.location = "redirect_page.html";</script>';
exit;
?>
