What are some key considerations when designing a survey manager in PHP for user-generated questions and unlimited answer options?

When designing a survey manager in PHP for user-generated questions and unlimited answer options, it is important to dynamically generate input fields for both the questions and answer options. This can be achieved by using arrays to store the user input data and iterating through them to display the form fields. Additionally, proper validation should be implemented to ensure that the user input is sanitized and secure. 

<?php
// Sample PHP code for survey manager with user-generated questions and unlimited answer options

// Initialize arrays to store questions and answers
$questions = [];
$answers = [];

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Retrieve user input for questions
    $questions = $_POST['questions'];

    // Retrieve user input for answers
    foreach ($_POST['answers'] as $key => $value) {
        $answers[$key] = explode(',', $value);
    }

    // Display the submitted questions and answers
    foreach ($questions as $key => $question) {
        echo "Question: $question <br>";
        echo "Answers: ";
        foreach ($answers[$key] as $answer) {
            echo "$answer, ";
        }
        echo "<br><br>";
    }
}
?>

<form method="post">
    <label for="questions">Enter your question:</label>
    <input type="text" name="questions[]"><br>

    <label for="answers">Enter your answers (separate with comma):</label>
    <input type="text" name="answers[0]"><br>

    <button type="button" id="add-answer">Add Answer</button><br>

    <input type="submit" value="Submit">
</form>

<script>
    document.getElementById('add-answer').addEventListener('click', function() {
        var answerInput = document.createElement('input');
        answerInput.setAttribute('type', 'text');
        answerInput.setAttribute('name', 'answers[]');
        document.querySelector('form').appendChild(answerInput);
    });
</script>
