README

A library for cookie management.

Features

• Manage your cookies
• Encrypt cookie with Crypt library(Optional)
• Manage SameSite
• Check useragent's support for SameSite

Install

composer

composer require mmdm/sim-cookie

Or you can simply download zip file from github and extract it, then put file to your project library and use it like other libraries.

Just add line below to autoload files:

require_once 'path_to_library/autoloader.php';

and you are good to go.

How to use

// to instantiate a cookie object
$cookie = new Cookie();

// then use cookie methods like
$cookie->get($cookie_name);

Use with Crypt library

If you need more security on cookies, use Crypt library.

// send crypt instance through cookie
// constructure (dependency injection)
$cookie = new Cookie($crypt);
// now your cookies are safe

If you don't need some of your cookies to be secure, pass false as last parameter of setValue of ISetCookie method.
