How can PHP sessions be utilized to transfer variables between pages in a multi-page form?

To transfer variables between pages in a multi-page form using PHP sessions, you can store the form data in session variables on one page and retrieve it on subsequent pages. This allows you to maintain the data across multiple pages until the form is submitted. 

// Page 1: Store form data in session variables
session_start();
$_SESSION['name'] = $_POST['name'];
$_SESSION['email'] = $_POST['email'];

// Page 2: Retrieve form data from session variables
session_start();
$name = $_SESSION['name'];
$email = $_SESSION['email'];

// Page 3: Use the retrieved form data
session_start();
$name = $_SESSION['name'];
$email = $_SESSION['email'];
