How can PHP sessions be used to pass data between different pages in a form submission process?

PHP sessions can be used to pass data between different pages in a form submission process by storing the form data in session variables on one page and retrieving them on another page. This allows the data to persist across different pages without the need to pass it through URLs or hidden form fields. 

// On the first page where the form is submitted
session_start();
$_SESSION['form_data'] = $_POST;

// On the second page where the form data is needed
session_start();
if(isset($_SESSION['form_data'])){
    $form_data = $_SESSION['form_data'];
    // Now you can use $form_data to access the submitted form data
}
