unsetting cookie variable

[subwiz]

i have set some cookie variables. but when i try to unset them:

setcookie('reg_sname','');
setcookie('reg_name','');
setcookie('reg_email','');

i check after unsetting them:

if(!empty($reg_sname))

but it always shows that reg_sname has some value in it!

Cookies are set on the client. Whatever you do to them does not appear in your script until then next time the script is accessed by the client.
