What potential issues can arise when session data changes with each page refresh or when switching between pages in an IFrame?

Potential issues that can arise when session data changes with each page refresh or when switching between pages in an IFrame include losing user data or state information, causing unexpected behavior or errors in the application. To solve this issue, you can use session_regenerate_id() function to generate a new session ID for each page load, ensuring that the session data remains consistent throughout the user's session. 

<?php
session_start();

// Regenerate session ID
session_regenerate_id();

// Your code logic here
?>
