if I run this:
$today = date('Y-m-d H:i:s');
$expire = time()+(20*60);
$ssid = md5(rand()*1000000000);
setcookie('id', $ssid, $expire) or die("couldn't set cookie. login failed.");
It always dies. Any ideas why?
You must set the cookie before doing anything else that produces output. Once the HTTP headers are sent, it’s too late to set the cookie.
