if i want to delete and set a cookie with the same name?

[searain]

if i want to delete and set a cookie with the same name, the book "PHP for professionals" said that I would have to use

<?php
//set a new one
setcookie("username", "joe");
//delete an old one
setcookie("username");
?>

BECAUSE, PHP sends cookies to the server in the reverse order to that of setcookie() calles in php script.

So I have to set up the new one first and delete the old one later in the script order.

Is that true? or is that still true in the php 4.2?

I have trouble to verify this. In my test, this is WRONG!

to delete the cookie

just set the expire time

time()-1000000000000 (or any big number )

and your cookie will be deleted

it is wrong as of some minor version of 4.0..........so you should set the blank one first.
