How can PHP sessions be properly set and utilized to store form data for processing?

To properly store form data for processing using PHP sessions, you can start a session, store the form data in session variables, and then retrieve and process the data as needed. This ensures that the form data is persistently available across multiple pages or requests until the session is destroyed. 

<?php
session_start();

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $_SESSION['form_data'] = $_POST;
    // Process the form data here
}

// Retrieve and use the form data stored in session
if(isset($_SESSION['form_data'])) {
    $formData = $_SESSION['form_data'];
    // Use the form data as needed
}
?>
