How can PHP sessions be utilized to transfer data between pages in a multi-step form process?

To transfer data between pages in a multi-step form process using PHP sessions, you can store form data in session variables as the user progresses through the form. This allows the data to persist across multiple pages until the form is submitted. By setting and retrieving session variables, you can easily pass data between different steps of the form. 

<?php
// Start the session
session_start();

// Store form data in session variables
$_SESSION['step1_data'] = $_POST['step1_data'];
$_SESSION['step2_data'] = $_POST['step2_data'];
$_SESSION['step3_data'] = $_POST['step3_data'];

// Retrieve form data from session variables
$step1_data = $_SESSION['step1_data'];
$step2_data = $_SESSION['step2_data'];
$step3_data = $_SESSION['step3_data'];
?>
