The PHP $_COOKIE variable is used to retrieve a cookie value.

In the example below, we retrieve the value of the cookie named "user" and display it on a page:

<?php
// Print a cookie
echo $_COOKIE["user"];
// A way to view all cookies
print_r($_COOKIE);
?>

When deleting a cookie you should assure that the expiration date is in the past, to trigger the removal mechanism in your browser.

Examples:

PHP Code:

  <?php

// set the expiration date to one hour ago

setcookie ("TestCookie", "", time() - 3600);

setcookie ("TestCookie", "", time() - 3600, "/~rasmus/", ".example.com", 1);

?>
