How can PHP developers ensure a seamless user experience when refreshing pages after executing code in a new window?

When refreshing pages after executing code in a new window, PHP developers can use session variables to store the necessary data and ensure a seamless user experience. By storing the data in session variables, the information will persist across page refreshes and new windows, allowing the user to continue their interaction without losing any progress.

<?php
session_start();

// Store data in session variable
$_SESSION['data'] = $yourData;

// Retrieve data from session variable
$yourData = $_SESSION['data'];
?>
