        if($file != '.' && $file != '..') {
            echo '<a href="download.php?file=' . $file . '">' . $file . '</a><br>';
        }
    }
}

// Function to handle file downloads
function downloadFile($directory, $file) {
    $filepath = $directory . $file;
    if(file_exists($filepath)) {
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename="' . $file . '"');
        readfile($filepath);
        exit;
    } else {
        echo 'File not found.';
    }
}
