How can PHP sessions be effectively used to store form data across multiple pages?

To store form data across multiple pages using PHP sessions, you can capture the form data on the first page, store it in session variables, and then retrieve and display the data on subsequent pages by accessing the session variables.

// Start the session
session_start();

// Capture form data from the first page
$_SESSION['name'] = $_POST['name'];
$_SESSION['email'] = $_POST['email'];

// Retrieve and display the form data on subsequent pages
echo "Name: " . $_SESSION['name'];
echo "Email: " . $_SESSION['email'];
