You have a basic misunderstanding about how cookies work. The first time
you load up your page nothing is set and you issue:
setcookie("C_name",$name);
setcookie("C_email",$email);
Since $name and $email are empty, this will generate these SetCookie
headers in the response:
Set-Cookie: C_name=deleted; expires=Tue, 13-Mar-01 15:30:14 GMT
Set-Cookie: C_email=deleted; expires=Tue, 13-Mar-01 15:30:14 GMT
ie. it deletes the cookies unless $name and $email are set.
Now, when $name and $email are set, then of course these cookies will be
sent. But sending a cookie during a request doesn't affect the current
request in any way. A cookie is only effective on the subsequent request
when the browser decides to send it back to you. You obviously cannot
receive the cookie in the request that generated it. Universal rules of
causality are working against you here.
To summarize, there is absolutely no bug here.
