force download help

[mike760534211]

i am using a force download of files and the script i am using is:
<?php

$file = $_REQUEST['file'];

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

header("Content-Type: application/force-download");
header( "Content-Disposition: attachment; filename=".basename($file));

header( "Content-Description: File Transfer");
header('Accept-Ranges: bytes');
header('Content-Length: ' . filesize($file));
@readfile($file);

?>
and it is called from the following script:
<?php

function direcho($path) {
global $filetotal, $fullsize, $totaldirs;
  $ignore = array(".php",".gif");
    $ext = strtoupper(substr(strrchr($file_name, "."), 1));
if ($dir = opendir($path)) {
  while (false !== ($file = readdir($dir))) {
  if (is_dir($path."/".$file)) {                    // if it's a dir, check it's contents too
  if ($file != '.' && $file != '..' ) {            // but dont go recursive on '.' and '..'
    echo '<li><img src="folder.gif"><font color=red size=5>' . $file . '</font></li><ul>';
    direcho($path."/".$file );
    echo '</ul>';
    $totaldirs++;
  }
  }
  elseif(!stripos($file, ".php") && !stripos($file, ".gif")) {                      //if it's not a dir, just output.
  $tab = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
  $filesize = $tab . '(' . filesize ($path.'/'.$file ) . ' bytes)';
  echo "<li><A HREF=download.php?file=$file>$file</a></li>";
  $fullsize = $fullsize + filesize ($path.'/'.$file);
  $filetotal++;
  }
}
closedir($dir);
}
}

direcho('.');

$fullsize = round($fullsize / 1024 / 1024, 2);

echo "<font size=4 face=\"Arial, Helvetica, sans-serif\" color=red>
Total files - $filetotal files

Total dirs - $totaldirs directories

Total size - $fullsize MB
";
?>
which lists all the files in a directory, generatesa a link to the file and then forces the download from the link.
the problem is that when the download runs it does not download the complete file.  it makes the file a random size when downloading and does not force download the entire file.

can someone help with this please.

When I download one of the files and open it in note page it contains the following error message:
<br />
<b>Warning</b>:  filesize() [<a href='function.filesize'>function.filesize</a>]: stat failed for [file.ext] in <b>%webroot%\download.php</b> on line <b>14</b><br />

in my script it lists the items in a directory and all the subdirectories when you download a file that is not in a sub-directory it will download the file fine.  but if you click a link to a file that is in a sub direcotry it wont download the file correctly because it cant read the file size.  how would i correct this.

function direcho($path) {
global $filetotal, $fullsize, $totaldirs;
  $ignore = array(".php",".gif");
    $ext = strtoupper(substr(strrchr($file_name, "."), 1));
if ($dir = opendir($path)) {
  while (false !== ($file = readdir($dir))) {
  if (is_dir($path."/".$file)) {                    // if it's a dir, check it's contents too
  if ($file != '.' && $file != '..' ) {            // but dont go recursive on '.' and '..'
    echo '<li><img src="folder.gif"><font color=red size=5>' . $file . '</font></li><ul>';
    direcho($path."/".$file );
    echo '</ul>';
    $totaldirs++;
  }
  }
  elseif(!stripos($file, ".php") && !stripos($file, ".gif")) {                      //if it's not a dir, just output.
  $tab = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
  $filesize = $tab . '(' . filesize ($path.'/'.$file ) . ' bytes)';
  echo "<li><A HREF=download.php?file=$file>$file</a></li>";
  $fullsize = $fullsize + filesize ($path.'/'.$file);
  $filetotal++;
  }
}
closedir($dir);
}
}
