I'm having a bit of a problem with deleting a cookie. I have this code:
PHP Code:
if ($_GET['logout'] == "true")
{
    
$_SESSION = array();
    
session_destroy();
    
setcookie("loggedin""TRUE"time()-(3600 24));//the line with the problems

for some reason, it is giving a "headers already sent" error. What is wrong?
