How can PHP sessions be utilized to store temporary form data in a multi-page form scenario?

When dealing with a multi-page form scenario in PHP, you can utilize sessions to store temporary form data as the user navigates through the different pages. This allows you to maintain the form data across multiple pages until the form is submitted, ensuring a seamless user experience. 

<?php
session_start();

// Check if form data has been submitted
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Store form data in session variables
    $_SESSION['name'] = $_POST['name'];
    $_SESSION['email'] = $_POST['email'];
    // Add more form fields as needed
}

// Retrieve form data from session variables
$name = isset($_SESSION['name']) ? $_SESSION['name'] : '';
$email = isset($_SESSION['email']) ? $_SESSION['email'] : '';
// Add more form fields as needed
?>
