        $quizData = WpProQuiz::with('questions')->where('id', $quizid)->first();

        $quizModels = [];
        if ($quizData) {
            $allquestions = $quizData->questions;
            foreach ($allquestions as $question) {
                $serializedAnswerData = rtrim($question->answer_data);
                $unserializedAnswerData = unserialize($serializedAnswerData);

                $answers = [];

                // Iterate through incomplete objects and treat them as arrays
                foreach ($unserializedAnswerData as $answerObject) {
                    // Convert the __PHP_Incomplete_Class objects to arrays
                    $answerArray = [
                        '_answer' => property_exists($answerObject, '_answer') ? $answerObject->_answer : null,
                        '_html' => property_exists($answerObject, '_html') ? $answerObject->_html : null,
                        '_points' => property_exists($answerObject, '_points') ? $answerObject->_points : null,
                        '_correct' => property_exists($answerObject, '_correct') ? $answerObject->_correct : null,
                        '_sortString' => property_exists($answerObject, '_sortString') ? $answerObject->_sortString : null,
                        '_sortStringHtml' => property_exists($answerObject, '_sortStringHtml') ? $answerObject->_sortStringHtml : null,
                        '_mapper' => property_exists($answerObject, '_mapper') ? $answerObject->_mapper : null,
                    ];

                    $answers[] = $answerArray;
                }

                // Now $answers is an array of associative arrays
                $quizModels[] = $answers;
            }
        }

        return $quizModels;
    }
