blank out all headers

[Anon]

i am writing a few client application that will query the web server to get some status variables, but instead of stripping out the headers on the client side (which is how i do it now) how can i make this code:

<?php
echo "sent to client";
?>

ONLY send "sent to client" with NO header or footer information?

the reason i say footer information is because when i view the exact packets being sent, many times there is a 0 at the end that the client also has to strip off.

thanks
