setcookie function is used for setting up a cookie. In the following example, if you use $_COOKIE command, you will view one cookie value, and if you see print_r ($_COOKIE), you will view all cookie value.
We have set the cookie value for up to one month duration.
setcookie("cookie", "Rose India", $expire);
echo $_COOKIE["cookie"]; # view one cookie value
