POSymfony2, print_r on collection of objects never completes

copied!<p>I am still new to Symfony2, and I am struggling my but off. I would actually like a proper answer to this question: <a href="https://stackoverflow.com/questions/19545916/symfony2-sessions-store-retrieve-array-collection-of-items-in-session">Symfony2 Sessions > Store & Retrieve array/collection of items in session</a> , but in the meantime I have had to resort to some "dirty" PHP using $_SESSION. However, I seem to have run into a snag where my function never completes. I am pretty sure it is because the question entity has a many to one mapping with the Quiz entity (So a quiz has questions, and each question has a quiz, which has questions, etc, etc, bad loop), but I do not know how to fix this. My code looks as follows:</p> <pre><code>public function nextQuestionAction() { $data = $this->getRequest()->request->all(); if (!isset($_SESSION['questions'])) { $quiz = $this->getDoctrine() ->getRepository('CriticalReadingQuizBundle:Quiz') ->find($data['quiz_id']); $questions = $quiz->getQuestions(); print_r($questions); die(); $_SESSION['questions'] = $questions; $question = $questions[0]; } else { foreach($_SESSION['questions'] as $key => $question) { if ($question['id'] == $data['question_id']) { if(isset($_SESSION['questions'][$key+1])) $question = $_SESSION['questions'][$key+1]; else { unset($_SESSION['questions']); } } } } return $this->createJsonResponse($question); } </code></pre> <p>I put in the print_r($questions); die(); to see what I get in my questions, but no surprise, that doesn't completeI either. I know that am doing/missing something stupid, but I do not know what it is. Any help will be greatly appreciated.</p>
