What are the potential pitfalls of using variable variables in PHP for handling survey data?

Using variable variables in PHP for handling survey data can lead to confusion, security vulnerabilities, and difficult debugging. It is better to use arrays to store survey data, as it provides a more organized and secure way to handle the information. 

// Using arrays to store survey data instead of variable variables
$surveyData = array(
    'question1' => $_POST['question1'],
    'question2' => $_POST['question2'],
    'question3' => $_POST['question3']
);
