How can PHP be used to automatically refresh a page after a download process?

To automatically refresh a page after a download process in PHP, you can use the header() function to set the refresh interval and redirect the user back to the page. This can be done by sending a header with the "Refresh" value set to the number of seconds before the page should be refreshed, along with the URL of the page.

<?php
// Start the download process here

// Redirect back to the page after 5 seconds
header("Refresh: 5; URL=your_page_url_here.php");
?>
