PHP Library for Decoding TCF2 Consent Strings

We created this utility class to be able to have a fast and lightweight library for decoding TCF2 consent strings.

Installation

Require the package via composer

composer require mobilefuse/php-tcf2-decoder

Usage

use MobileFuse\Tcf2Decoder\ConsentString;

$consent = ConsentString::decode("COvFyGBOvFyGBAbAAAENAPCAAOAAAAAAAAAAAEEUACCKAAA.IFoEUQQgAIQwgIwQABAEAAAAOIAACAIAAAAQAIAgEAACEAAAAAgAQBAAAAAAAGBAAgAAAAAAAFAAECAAAgAAQARAEQAAAAAJAAIAAgAAAYQEAAAQmAgBC3ZAYzUw");

var_dump($consent);
