Are there best practices for handling sessions in PHP to ensure continuity and security across different pages or sections of a website?

When handling sessions in PHP, it is important to ensure continuity and security across different pages or sections of a website. To achieve this, best practices include starting the session at the beginning of each page, setting session variables securely, and destroying the session when it is no longer needed. 

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

// Set session variables securely
$_SESSION['user_id'] = htmlentities($_POST['user_id']);

// Destroy the session when it is no longer needed
session_destroy();
?>
