This helper is loaded using the following code::

    $this->load->helper('cookie');

Available Functions
===================

The following functions are available:


.. php:function:: set_cookie($name[, $value = ''[, $expire = 0[, $domain = ''[, $path = '/'[, $prefix = ''[, $secure = NULL[, $httponly = NULL[, $samesite = NULL]]]]]]]])

    :param    mixed    $name: Cookie name *or* associative array of all of the parameters available to this function
    :param    string    $value: Cookie value
    :param    int    $expire: Number of seconds until expiration
    :param    string    $domain: Cookie domain (usually: .yourdomain.com)
    :param    string    $path: Cookie path
    :param    string    $prefix: Cookie name prefix
    :param    bool    $secure: Whether to only send the cookie through HTTPS
    :param    bool    $httponly: Whether to hide the cookie from JavaScript
    :param    string    $samesite: SameSite attribute ('Lax', 'Strict', 'None')
    :rtype:    void

    This helper function gives you friendlier syntax to set browser
    cookies. Refer to the :doc:`Input Library <../libraries/input>` for
    a description of its use, as this function is an alias for
    ``CI_Input::set_cookie()``.

.. php:function:: get_cookie($index[, $xss_clean = FALSE])

    :param    string    $index: Cookie name
    :param    bool    $xss_clean: Whether to apply XSS filtering to the returned value
    :returns:    The cookie value or NULL if not found
    :rtype:    mixed

    This helper function gives you friendlier syntax to get browser
    cookies. Refer to the :doc:`Input Library <../libraries/input>` for
    detailed description of its use, as this function acts very
    similarly to ``CI_Input::cookie()``, except it will also prepend
    the ``$config['cookie_prefix']`` that you might've set in your
    *application/config/config.php* file.

.. php:function:: delete_cookie($name[, $domain = ''[, $path = '/'[, $prefix = '']]])

    :param    string    $name: Cookie name
    :param    string    $domain: Cookie domain (usually: .yourdomain.com)
    :param    string    $path: Cookie path
    :param    string    $prefix: Cookie name prefix
    :rtype:    void

    Lets you delete a cookie. Unless you've set a custom path or other
    values, only the name of the cookie is needed.
    ::

        delete_cookie('name');

    This function is otherwise identical to ``set_cookie()``, except that it
    does not have the value and expiration parameters. You can submit an
    array of values in the first parameter or you can set discrete
    parameters.
    ::

        delete_cookie($name, $domain, $path, $prefix);
