cookie problem for logout script.. (n00b question probably)

[snek_one]

Alright, I am using a downloaded script from Hotscripts which I've been editing to my heart's content for a while now.. But I am running into some difficulities..

For some weird reason I can not make a log-out script which works!

Here's the (relavent) code snippets from the script:

$md5str = MD5( TIME() );
$cookie_val = "$username-$encrypted_password-$md5str";
$setcookie( "php_prof_auth", $cookie_val, time()+EXPIRE);

I tried writing my own little log-out script with a bit of help from the PHP manual, but for some weird reason it does not want to work:

$cookie = $_COOKIE['php_prof_auth'];
if(@setcookie ("php_prof_auth", $cookie, time() - 14400)){
	echo "It worked!";
} else {
	echo "It didn't work!<BR><BR>";
	echo "DEBUG:<BR>";
	echo $cookie;
	}

The echo of $cookie shows this:
"prof-pr7fXtm8GZqPo-d6b6b959352e39336d1c773084961ffa"

Does anybody have any ideas on this??

I got a deadline in 4 days and this is really starting to pee me off 😉

ok, well I changed the time()+NUMBER line to just "0" and it logs out automatically when the browser is closed now.. I guess that'll do for now but if anyone could still clear this up I'd be very greatful...

I hate not knowing the answer once I've created the question 😉

i'm guessing you want to logout from the cookie ok

setcookie("cookie_name", "", time() - 86400);

that code sets $_COOKIE[cookie_name] to " ", and gives it a minus date, which makes it expired
