What are the benefits of using hidden input fields in PHP forms for passing data between different sections of a website?

Hidden input fields in PHP forms allow you to pass data between different sections of a website without displaying the information to the user. This can be useful for storing information that needs to be carried over from one page to another, such as user authentication tokens or session identifiers. By using hidden input fields, you can securely transfer data without exposing it to potential security risks. 

<form method="post" action="next_page.php">
    <input type="hidden" name="user_id" value="<?php echo $user_id; ?>">
    <input type="submit" value="Continue to Next Page">
</form>
