What are some best practices for managing sessions in a PHP-based community website?

One best practice for managing sessions in a PHP-based community website is to set session cookie parameters to secure and httponly to prevent session hijacking and cross-site scripting attacks. Another best practice is to regenerate the session ID after a user logs in or out to prevent session fixation attacks. Additionally, always validate and sanitize user input before storing it in the session to prevent injection attacks. 

// Set session cookie parameters
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true
]);

// Regenerate session ID after login or logout
session_regenerate_id(true);

// Validate and sanitize user input before storing in session
$_SESSION['username'] = filter_var($_POST['username'], FILTER_SANITIZE_STRING);
