Re: 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='') {

Outside your function, or in, I don't care, define a variable/constant that will be used as a buffer size. $buffer = 1024;

if ( is_file("$file") ) {

    if ($mime == '') {
      $mime=exec("file -i -b $file");
    }
    $STRG="; filename=\"" . basename($file) . "\"";

Don't do the following...

XXXX>     $FSIZE=filesize("$file");

    if ($type == 'show') {
      header("Content-Disposition: inline" . $STRG );
    } else {
      header("Content-Disposition: attachment" . $STRG);
    }
    header("Content-Type: " . $mime);
    $HANDLER=fopen("$file", r);

Then here, do this... $current_size = 0; while ( !feof($HANDLER) ) { $current_size += $buffer; echo fread($HANDLE, $buffer); } Now, do what you want with $current_size Maybe have a variable that you check it against that contains the users allow amount of transfer... $current_size = 0; while ( !feof($HANDLER) && $current_size < $allowed_limit ) { $current_size += $buffer; echo fread($HANDLE, $buffer); } Hope this gets you leading down the right path...

    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. Thanks, Greetings and nice Day/Evening
