Destroy a cookie

[Nixon]

Hi all, how do you destroy a cookie? I have read up on it and nowhere seems to give a method that works, I set the cookie using this method:

setcookie ( "sessionusername", "$username", time()+86400 );
setcookie ( "sessionpassword", "$password", time()+86400 );

and then 'try' and destroy it using this method:

setcookie ( "sessionusername" );
setcookie ( "sessionpassword" );

I have also tried setting the time into minus figures. Any ideas?

Thanks.

set the cookie back using passed time.
