How can one ensure session persistence between different pages in a PHP application?

To ensure session persistence between different pages in a PHP application, you need to start the session on each page where you want to access session variables. This can be done by calling session_start() at the beginning of each page. This allows you to store and retrieve session data across multiple pages within the same session. 

<?php
session_start();

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

// Retrieve session variables
echo $_SESSION['username'];
?>
