How can hidden fields in a form be utilized to pass variables between PHP pages?

Hidden fields in a form can be utilized to pass variables between PHP pages by including the variables as values in the hidden input fields within the form. When the form is submitted, the variables will be sent along with the other form data to the PHP page, where they can be accessed using the $_POST or $_GET superglobals. 

<form method="post" action="process.php">
  <input type="hidden" name="variable1" value="value1">
  <input type="hidden" name="variable2" value="value2">
  <!-- Other form fields here -->
  <input type="submit" value="Submit">
</form>
```

In the process.php file:

```php
$variable1 = $_POST['variable1'];
$variable2 = $_POST['variable2'];

// Use the variables as needed
