What security risks should be considered when developing an online shop in PHP, especially regarding session management and data handling?

One security risk to consider when developing an online shop in PHP is session hijacking, where an attacker can steal a user's session and impersonate them. To mitigate this risk, you should use secure session management techniques, such as regenerating session IDs after a successful login or periodically throughout the session. 

// Start secure session management
session_start();

// Regenerate session ID after successful login
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in'] === true) {
    session_regenerate_id();
}
