What are some best practices for passing input values through multiple pages in a PHP form?

When passing input values through multiple pages in a PHP form, it is best practice to use sessions to store the values temporarily. This ensures that the values are retained as the user navigates through the form pages. By using sessions, you can easily access the input values on each page without the need to constantly pass them through URLs or hidden form fields. 

// Start a session to store input values
session_start();

// Set input values in session variables
$_SESSION['name'] = $_POST['name'];
$_SESSION['email'] = $_POST['email'];

// Retrieve input values from session variables on subsequent pages
$name = $_SESSION['name'];
$email = $_SESSION['email'];
