How can PHP developers use hidden input fields to improve form submission handling and processing?

When handling form submissions in PHP, developers can use hidden input fields to pass additional data along with the form submission. This hidden data can be used for various purposes such as identifying the source of the form submission or storing session information. By including hidden input fields in the form, PHP developers can enhance the processing and handling of form submissions. 

<form method="post" action="process_form.php">
    <input type="hidden" name="source" value="contact_form">
    <input type="hidden" name="session_id" value="<?php echo session_id(); ?>">
    <!-- Other form fields here -->
    <button type="submit">Submit</button>
</form>
