RE: [PHP-WIN] "Headers already sent" error message

First impression... From your code: echo "$type, $filename"; header ("Content-Type: $type; Content-Disposition: attachment; filename=$filename" ); The echo is sending output to the browser, and since it does this before the header command the header doesn't work. Try taking out that echo and see what happens.
