Answers in Quiz listed randomly

The Answers in Quiz should be listed randomly.

That should work

I used the Shuffle function to mix the Array.

quiz.php

<form action="result.php" method="post" name="quiz" >
            <?php

                $quiz = Database::getInstance ()->createQuiz ( $_GET ['id'], $categories );
//              $lastId = Database::getInstance ()->getLastId();
                if (!(isset($_SESSION['login'])) or ($_SESSION['login'] == false)){
                    ?>
                <div class="col-md-12">
                <div class="alert alert-danger" role="alert">

                nicht angemeldet bist.

                foreach ( $quiz->__get ( 'questions' ) as $question ) {
