How can hidden fields be used in PHP forms to ensure specific parameters are included in form submissions?

Hidden fields can be used in PHP forms to ensure specific parameters are included in form submissions without the user being able to see or modify them. This is useful for passing data that should not be changed by the user, such as user IDs or security tokens. By adding hidden fields to the form, the parameters are automatically included in the form submission. 

<form method="post" action="process_form.php">
    <input type="hidden" name="user_id" value="<?php echo $user_id; ?>">
    <input type="hidden" name="csrf_token" value="<?php echo generate_csrf_token(); ?>">
    <!-- Other form fields -->
    <button type="submit">Submit</button>
</form>
