How can PHP session values be maintained and shared across multiple frames within a website?

To maintain and share PHP session values across multiple frames within a website, you can use the session_start() function at the beginning of each PHP script that needs to access session values. This function initializes the session data for the current session. By doing this, you can ensure that session values are maintained and shared across all frames within the website. 

<?php
session_start();

// Set session variables
$_SESSION['user_id'] = 12345;
$_SESSION['username'] = 'john_doe';

// Access session variables
echo 'User ID: ' . $_SESSION['user_id'];
echo 'Username: ' . $_SESSION['username'];
?>
