Notes

"htmlspecialchars" is a function in PHP that is used to convert special characters to their corresponding HTML entities. This is important to prevent potential security vulnerabilities, such as cross-site scripting (XSS), where malicious users can inject scripts into your web pages.

"session_regenerate_id" is a function in PHP that is used to regenerate the session ID. It's often employed as a security measure to help prevent session fixation attacks. Session fixation is an attack where an attacker sets the session ID of a user, and if the user logs in with that fixed session ID, the attacker gains access to the user's session.

By periodically regenerating the session ID, even if the session is compromised, an attacker would need to continually guess or acquire the new session ID to maintain control over the session.
