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");].

Thanks in advance!

You cannot use headers after you print (echo) anything (including
errors produced by your script).

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