HELP! cookie check sniplet

seabird

I retrieved this little code from the sniplet page.

<?PHP
setcookie("TEMPCOOKIE", "NOVALUE", time() + 60 * 60);

$cookieinfo = $HTTP_COOKIE_VARS["TEMPCOOKIE"];

if ($cookieinfo == "$cookieinfo") {
echo "you have cookies enabled";
exit;
} else {
echo "you have cookies disabled";
exit;
}
?>

It works fine inside it's own file, but when I paste the code into another site I get a error message stating:

Warning:

Cannot add header information - headers already sent by (output started at c:\apache\htdocs\php_new\tmpgutk33o2t3.php:9) in c:\apache\htdocs\php_new\tmpgutk33o2t3.php on line 50

Where did it go wrong????

the output tells you: in this script on line 9, something was already outputted. That may be a single space before <?php or text or whatever... before any (!) output is send, you have to send your cookies;

This line before the header...

<?
setcookie("TEMPCOOKIE", "NOVALUE", time() + 60 * 60);
?>

Now echo out your coookie value somwhere in the body of the page by using..

echo $TEMPCOOKIE;

Thanx guys,
it works.

one more thing,

I'm running this localhost for now, and I wanted to see if it would also say cookie disabled. I set my firewall to block the cookie, but it still excepts the cookie and says (correct) cookies enabled.

Why won't it block my cookie??

Firewalls don't block cookies, browser settings do. If you are using IE, you go into tools options and in the privacy tab you can disable them or enable them. Cookies are passed to the client as part of the HTTP process and therefore look just like a page request response.
