PHP 7.0.6 Released

    $_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.

    beware, dots (.) in cookie names are replaces by underscores (_)

    The value of $_COOKIE is determined by the content of cookies received in the user agent's request.

    If you set a cookie (ie send it to the browser), it won't be sent back until the next request and so the data won't be present in $_COOKIE.
