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



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


Example #1 $_COOKIE example

echo 'Hello ' htmlspecialchars($_COOKIE["name"]) . '!';

Assuming the "name" cookie has been set earlier

The above example will output something similar to:

Hello Hannes!



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.

$_COOKIE returns an array if there are more than one cookie saved under the given key.

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.
