# $_COOKIE

# $HTTP_COOKIE_VARS [deprecated]

$_COOKIE -- $HTTP_COOKIE_VARS [deprecated] — HTTP Cookies

### Description

An associative array of variables passed to the current script via 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)

### Changelog

Version | Description
--- | ---
4.1.0 | Introduced $_COOKIE that deprecated $HTTP_COOKIE_VARS.

### Examples

Example #1 $_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!

### Notes

> 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.
