$_COOKIE - HTTP Cookies

$HTTP_COOKIE_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_COOKIE_VARS and $_COOKIE are different
variables and that PHP handles them as such)

$_COOKIE example
<?php
echo 'Hello ' . htmlspecialchars($_COOKIE["name"]) . '!';
?>
Assuming the "name" cookie has been set earlier
The above example will output something similar to:
Hello Hannes!
Note
This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script.
There is no need to do global $variable; to access it within functions or methods.
