How can hidden fields be used to improve form submission handling in PHP?

Hidden fields can be used to pass additional data along with form submissions in PHP. This can be useful for storing information that should not be visible or editable by users, such as user IDs or timestamps. By including hidden fields in a form, this data can be sent to the server along with the rest of the form data, allowing for more efficient and accurate processing of form submissions. 

<form method="post" action="submit_form.php">
    <input type="hidden" name="user_id" value="<?php echo $user_id; ?>">
    <input type="hidden" name="timestamp" value="<?php echo time(); ?>">
    
    <!-- Other form fields go here -->
    
    <input type="submit" value="Submit">
</form>
