In php, You can use the setcookie() function to set a cookie.
Let’s see the basic syntax of used to set a cookie in php:
<?php setcookie(cookie_name, cookie_value, [expiry_time], [cookie_path], [domain], [secure], [httponly]); ?>

To retrieve or access a cookie in PHP, you can use $_COOKIE variable.

echo 'Hello '.($_COOKIE['first_name']!='' ? $_COOKIE['first_name'] : 'Guest');

<?php
setcookie("first_name", "Tutsmake.com", time() - 360,'/');
