How can users maintain their session across different pages in PHP?

Users can maintain their session across different pages in PHP by starting the session using session_start() at the beginning of each page where session data needs to be accessed. This ensures that the session data is available across multiple pages until the session is destroyed. Additionally, session variables can be set and accessed using the $_SESSION superglobal array. 

<?php
// Start the session
session_start();

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

// Access the session variable on another page
session_start();
echo $_SESSION['username'];
?>
