$_COOKIE

$HTTP_COOKIE_VARS [deprecated]

(PHP 4 >= 4.1.0, PHP 5, PHP 7)

$_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.

Cookies with the same name the first cookie is used. Clients will send cookies with longer path before cookies with shorter path. This comes from RFC 6265 which says "Cookies with longer paths are listed before cookies with shorter paths.". So you get the best matching cookie for your current request.
