What are the best practices for starting a session in PHP and ensuring that it is maintained across multiple pages?

To start a session in PHP and ensure that it is maintained across multiple pages, you should use the session_start() function at the beginning of each page where you want to access session variables. Additionally, you should set session variables using the $_SESSION superglobal array and make sure to call session_write_close() at the end of each page to ensure that the session data is saved. 

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

// Set session variables
$_SESSION['username'] = 'john_doe';
$_SESSION['email'] = 'john@example.com';

// Access session variables
echo 'Username: ' . $_SESSION['username'];

// End the session
session_write_close();
?>
