Help -- Headers already sent....

session_start()
session_destroy();
echo "<center><font color=red>You are now logged
out!</strong></font></center><br />";
header("Location: index.php");

Can somebody tell me why this bit of code in my logout script doesn't
work? what it's supposed to do is destroy the current session and then
redirect to the home page, but it says that 'Headers already sent' when
i try to do the redirect [header("location: index.php");].

RTFM: <http://www.php.net/session_start>
<http://www.php.net/header>

especially this bit:[color=blue]

Headers must be sent before anything else. So either make sure you do
not send anything before the headers or use output buffering. Check
ob_start() and ob_end_flush() in the PHP manual.
