Download counter of exe file in PHP - php

Question

I have a problem with counting downloads of file. There will be no problem if a link to the download file would look like this: http:// your.site.domain/download.php?file=filename.exe&customer=ABC_423. However my customer want to count statistics from link like this: http:// your.site.domain/downloadsfolder/ABC_423/filename.exe and also he needs to hotlink that link on other sites.
I think there would be solution in .htaccess file, but I don't know how to make a proper redirect.
My PHP script looks like this:
session_start();
define('SERVER_NAME', 'www.siteaddress.domain');
define('DOWNLOAD_PATH', 'http:// siteaddress.domain/versions/download');
define('DOWNLOAD_FILE', 'Setup.exe');
$filename = DOWNLOAD_PATH . '/' . $_GET['customer'] . '/' . DOWNLOAD_FILE;
$headers = get_headers($filename);
if ($headers[0] == 'HTTP/1.1 200 OK'){
// file exists, begin download procedure
if(isset($_GET['customer'])){
// begin update statistics
// mysql query to update specified row
}
// headers for downloading file
header("Content-Type: application/force-download");
header('Content-Type: application/x-unknown');
header("Content-Type: application/octet-stream");
//header("Content-Type: application/download"); // not sure if needed
header("Content-Disposition: attachment; filename=".basename($filename).";");
header("Accept-Ranges: bytes");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".remote_filesize(SERVER_NAME, $filename));
ob_clean();
flush();
readfile($filename);
exit;
}else{
echo 'File not found';
exit;
}

This is a simple RewriteRule in .htaccess. Something like this:
RewriteEngine On
RewriteRule ^/downloadsfolder/(.*)/(.*) /download.php?file=$2&customer=$1 [L]
Observe how a random char sequence is detected with (.*) and then used with $1 and $2 for each detected item in the translated URL.
Hope that helped!
