fread(), file_get_contents(), and readfile() all store the data in memory -
there's no real way (AFAIK) of just sending right from disk.
However - something that might work is iteratively using stream_get_contents
(http://ca3.php.net/manual/en/function.stream-get-contents.php). You could
read the file in chunks, then destroy each chunk when you're done reading
it.
