$_COOKIE

(PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8)

$_COOKIE — HTTP Cookies

Description

An associative array of variables passed to the current script via HTTP Cookies.

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.
