How can hidden fields in HTML forms be utilized to pass data to PHP scripts?

Hidden fields in HTML forms can be utilized to pass data to PHP scripts by including them within the form tags but setting their type attribute to "hidden". This allows data to be sent along with the rest of the form data when the form is submitted without being visible to the user. In the PHP script, the hidden field values can be accessed using the $_POST or $_GET superglobals, depending on the form submission method. 

<form method="post" action="process_form.php">
  <input type="hidden" name="hidden_field" value="hidden_value">
  <!-- other form fields here -->
  <input type="submit" value="Submit">
</form>
```

In the PHP script (process_form.php):

```php
<?php
$hidden_value = $_POST['hidden_field'];
// Use $hidden_value as needed in the script
?>
