You will also add a submit button, which lets users to send the cookie values to the server. The page should display the previous cookie values when it is loaded.

<!DOCTYPE html>
<?php
    $cookie_name = "user";
    $cookie_value = "John Doe";
    setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day
?>
<html>
<body>

<?php
if(!isset($_COOKIE[$cookie_name])) {
   echo "Cookie named '" . $cookie_name . "' is not set!";
} else {
   echo "Cookie '" . $cookie_name . "' is set!<br>";
   echo "Value is: " . $_COOKIE[$cookie_name];
}
?>
<p><strong>Note:</strong> You might have to reload the page to see the value of the cookie.</p>
</body>
</html>
