Let's look at your two setcookie() calls:
setcookie("cookie[andrea]", "$andrea")
setcookie("cookie[$andrea]", "")
Just for debugging purposes, assume $andrea is initialized prior to this
as follows:
$andrea = 29;
So, your code says that you want a cookie with the following name and
value (available on the next request):
$_COOKIE['cookie[andrea]'] = 29;
Is that really what you want?
Of course, it's very odd that if $andrea is not set, you want a cookie
like this:
$_COOKIE['cookie[]'] = '';
In addition, you will be generating a notice, because you're using
$andrea in the name of the cookie, although you're first making certain
that $andrea isn't set.
I'm also a bit concerned about where $andrea originates. Is this coming
from the user, and you're trusting it? That's a very dangerous practice.
If you explain your problem, we might be able to offer some help.
