Are there any common misconceptions or pitfalls when it comes to handling sessions in PHP, and how can developers avoid falling into these traps?

One common pitfall when handling sessions in PHP is not properly securing the session data. Developers should always use HTTPS to encrypt the data transferred between the client and server to prevent eavesdropping. Additionally, developers should avoid storing sensitive information in the session data and regularly regenerate session IDs to prevent session fixation attacks. 

<?php
// Start secure session
session_start([
    'cookie_lifetime' => 86400, // 1 day
    'cookie_secure' => true, // only send cookie over HTTPS
    'cookie_httponly' => true, // prevent client-side access to the cookie
]);

// Regenerate session ID to prevent session fixation
session_regenerate_id(true);
?>
