What are the benefits of using session variables in PHP for storing form data temporarily before final processing?

Using session variables in PHP to store form data temporarily before final processing can provide benefits such as maintaining data across multiple pages, ensuring data persistence even if the page is refreshed, and allowing for easier error handling and validation before submitting the form. 

<?php
session_start();

// Store form data in session variables
$_SESSION['name'] = $_POST['name'];
$_SESSION['email'] = $_POST['email'];
$_SESSION['message'] = $_POST['message'];

// Redirect to another page for final processing
header("Location: process_form.php");
exit;
?>
