Catalin,
Wow, that worked great, thanks.
I'm curious why you set a static buffer of 1024768... why not just do
filesize($file), as shown at http://www.php.net/fread ? Is it better
for memory usage to have a potentially smaller buffer? Also, you may
want an fclose($fp) after the file has been downloaded.
So is this a bug in PHP 5 or are they just purposely limiting the
abilities of the "readfile" command?
