How can data be passed from one step to another in a multi-step form in PHP without using MySQL?

When working with a multi-step form in PHP, data can be passed from one step to another by using sessions to store the form data temporarily. By storing the form data in session variables, it can be accessed and manipulated across different steps of the form without the need to use MySQL or a database. 

<?php
session_start();

// Step 1: Collect form data and store in session variables
$_SESSION['name'] = $_POST['name'];
$_SESSION['email'] = $_POST['email'];

// Step 2: Retrieve form data from session variables
$name = $_SESSION['name'];
$email = $_SESSION['email'];

// Step 3: Display the form data in the next step
echo "Name: $name <br>";
echo "Email: $email";

// Additional steps can continue to use and manipulate the form data stored in session variables
?>
