How can file downloads be managed in PHP without affecting database updates on click events?

When handling file downloads in PHP, it's important to ensure that database updates are not affected by click events. One way to achieve this is by using a separate PHP script to handle the file download process, separate from the script that performs database updates. This way, the database updates can continue uninterrupted while the file download is being processed. 

<?php
// Separate PHP script for handling file download
if(isset($_GET['file'])) {
    $file = $_GET['file'];
    $filepath = 'path/to/files/' . $file;

    if(file_exists($filepath)) {
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename=' . basename($filepath));
        header('Expires: 0');
        header('Cache-Control: must-revalidate');
        header('Pragma: public');
        header('Content-Length: ' . filesize($filepath));
        readfile($filepath);
        exit;
    } else {
        echo 'File not found.';
    }
}
?>
