Cookies not being saved?

Question

PHP

You need to display a variable that shows how many times the user has seen the banner.
In the banner code we have:
<?php
setcookie("Vas","0",time()+86400,"/","$v");
... // Banner code
$_COOKIE[$v]++;
echo('Views: '.($_COOKIE[$v]));
?>
Why doesn't $_COOKIE[$v] increase with every browser refresh?

Answer 1

because only setcookie sets/changes cookies.

Answer 2
