How can hidden fields be used in PHP forms to pass information to another script?

Hidden fields can be used in PHP forms to pass information to another script by including them within the form tags but setting their type attribute to "hidden". This allows data to be sent along with the form submission without it being visible or editable by the user. The hidden fields can then be accessed in the receiving script using the $_POST or $_GET superglobals, depending on the form submission method. 

<form action="process.php" method="post">
  <input type="hidden" name="hidden_field_name" value="hidden_field_value">
  <!-- Other form fields here -->
  <input type="submit" value="Submit">
</form>
```

In the "process.php" script, you can access the value of the hidden field like this:

```php
$hiddenFieldValue = $_POST['hidden_field_name'];
