How can PHP sessions be managed effectively across different pages on a website?

To manage PHP sessions effectively across different pages on a website, you can use the session_start() function at the beginning of each page where you want to access session variables. This function initializes a session or resumes the current one based on a session ID passed via a GET or POST request, or a cookie. Make sure to set session variables using the $_SESSION superglobal array and unset them when they are no longer needed to keep the session data secure and organized. 

<?php
session_start();

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

// Access session variable
echo $_SESSION['username'];

// Unset session variable
unset($_SESSION['username']);
?>
