Jwt verify in php

Got it. I will post a working code for the new version. The key from twitch has to decoded.

function validate_twitch_jwt($jwt) {
    $secretKey = base64_decode("YOUR_KEY_FROM_TWITCH");
    try {
        $decoded = JWT::decode($jwt, new Key($secretKey, 'HS256'));
        return true;
    } catch (Exception $e) {
        $output['error'] = 'J An Error Occured';
        $output['error'] = $e->getMessage();
        echo json_encode($output);
    }
}
