problem with php sessions

[cyon]

hy,

I have a problem with php sessions.

these two lines:

<?php session_start();
echo session_id();
?>

shows the following error:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/cyonch/public_html/html/session.php:10) in /home/cyonch/public_html/html/session.php on line 10

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/cyonch/public_html/html/session.php:10) in /home/cyonch/public_html/html/session.php on line 10

has anyone an idea what the problem could be?

the site with the session can be found here:
