Deleting Cookies

[estrellas]

Why Cookies?
I'm using them for controlled access to certain pages. Here's how I create it:

if($_POST['Submit']){

	//assign a variable to the username the user input
	$username = $_POST['user'];

	//assign a password to the username the user input
	$password = $_POST['pass'];

	if ($username=="coolThing" && $password=="coolPass){
		// If username and password is right , store the session in a cookie
		setcookie ('logedin', '1',time()+30000); // Set the length of the cookie to 30000
		
		//Create the Session id's (as many as you want, can also do the same with cookied)
		$_SESSION['logedin'] = "1";
		$_COOKIE['logedin'] = "1";
		
}
}
?>

This works wonderfully.

The Problem?
LOGGING OUT.
Here's what I have right now and it doesn't seem to be working so well.

<?

// If the form was submited Log Off The User
if($_POST['logoff']){

// Delete the cookie
setcookie ('logedin','');
// Set its time to minus 300 (more secure)
setcookie ('logedin' , '',time()-300);
// End All Session ID'S
$_SESSION = array();
// KILL ALL SESSIONS
session_destroy();
//Rdirect User our
//Redirect user out
header("Location: login.php");
exit();
}

?>

do you guys have any clues why this is not deleting my cookie that is holding all of the login information?

here's the errors i'm getting by the way: (all 4 appear)

Warning: Cannot modify header information - headers already sent by ...

Warning: Cannot modify header information - headers already sent by ...

Warning: session_destroy(): Trying to destroy uninitialized session in ...

Warning: Cannot modify header information - headers already sent by ...

Thanks again and cheerio

For the first, second, and fourth errors, see section 1.4 of my FAQ "Debugging PHP code": faq434-2999

The third error is probably related to the same problem.
