How to count transfered kBytes in File-Download

Hello *,

currently I have a function:

----[ '/usr/share/tdphp-vserver/includes/02_functions.inc' ]------------
<snip>
function fncPushBinary($type='show', $file, $mime='') {
if ( is_file("$file") ) {
if ($mime == '') {
$mime=exec("file -i -b $file");
}
$STRG="; filename=\"" . basename($file) . "\"";
$FSIZE=filesize("$file");
if ($type == 'show') {
header("Content-Disposition: inline" . $STRG );
} else {
header("Content-Disposition: attachment" . $STRG);
}
header("Content-Type: " . $mime);
$HANDLER=fopen("$file", r);
echo fread($HANDLER, $FSIZE);
fclose($HANDLER);
exit();
} else {
$ERRNO=2;
$ERRTX=sprintf( T_gettext("The requested binary file does not exist.<p>%s"), $file );
fncError($ERRNO, $ERRTX, $ERRPAGE);
}
}
<snip>
------------------------------------------------------------------------

which I want to modify it to count the kBytes a user download and block
after a definde amount...

(there are too many peoples in the world which want to suck anything for
free and unlimited and no one cares who pay the stuff... even if I have
100 TByte free traffic on one of my bigger servers)

My problem is now

1) how to count partial downloads
2) how to allow users to make partial downloads

any suggestions?

Oh, I should note, that the URL's looks like:

/?what=music&where=h&section=foo&name=I_love_php5.ogg

and the input to the function is already sanitized.
