a good work around to this is using the ob_start() and ob_end_flush() functions. These functions essentially stop loading the page and let you add values that should have been added in the header information. So try it this way.

ob_start();
setcookie("xhcookie", $mahname, time() - 3600);
ob_end_flush();

This should let you expire your cookie.

well i was told that i cant have any echo or prints before the set cookie; so i deleted tem and i still get that smae error; please help me this is a urgent problem

any help will be appreciated; all i need to do is have a form and get the username and pazssword off it then check it against my database; if succesful set a cookie

If you have any html before setcookie, you will get an error. setcookie has to be before any html is shown.

I have noticed another problem you are setting your cookie to expire in the past rather than in the future.

This could cause a problem once the script is working as you won't have a cookie for othe pages to user to check if you are logged in.
