单击URL到不加载并停留在当前页面的php页面（仅加载cookie）

Question

I want to create an hyperlink() to a PHP file in server that runs the PHP without open a new page, staying in the page where I click the hyperlink.

Consideration 1: Without JS or jQuery, etc in the page where the <a> is. Consideration 2: PHP code has to run completely without open it in a new page. web user do not feel changes in the current page and stay in the same page.

HTML:

<a href="http://localhost/test_site/php/create_cookie.php?name=Alan&lastname=Harper">Save your name for future access.</a>

PHP:

<?php //create_cookie.php
`$cookie_name = "user_name";
$cookie_value = $_GET['name'] . " " . $_GET['lastname'];
setcookie($cookie_name, $cookie_value, time() + 86400, "/");
$_COOKIE['$cookie_name'] = $cookie_value;`

?>

Answer 1

Just redirect back in the PHP-file to the file with the link, and set the redirect-time to 0.

Something like header('location: <originalfile>'); at the bottom of the php-file.
