Implementing session management and user authentication in PHP web applications Mocktest

Prepared statements in user authentication help prevent SQL injection attacks by separating SQL logic from user input, ensuring that user-supplied data is treated as data and not executable SQL code.

Remember me functionality in PHP involves using persistent cookies with long expiration times to store a unique token on the user's device, allowing them to stay logged in across browser sessions.

Using HTTPS to encrypt session data during transmission ensures that session data exchanged between the client and the server is encrypted, preventing eavesdropping and tampering.

Regenerating session IDs after successful authentication in PHP helps prevent session fixation attacks by ensuring that each user is assigned a new session ID upon login, making it harder for attackers to hijack sessions.

The session_regenerate_id() function in PHP regenerates the session ID to prevent session fixation attacks by generating a new, unique session ID for the user.

The session_set_cookie_params() function in PHP is used to set session cookie attributes such as expiration time, path, domain, secure, and httponly flags.

Securely managing session data in PHP involves storing sensitive session data server-side, either in server memory, a database, or a session storage mechanism.

The session_write_close() function in PHP writes session data to the session file and closes the session, releasing the session lock and allowing other scripts to access the session file.

The session_destroy() function in PHP is used to destroy a session and delete all session data from the server, effectively logging the user out and terminating the session.

The recommended approach for handling session data in PHP forms is to use form validation to validate user input and include CSRF tokens to prevent cross-site request forgery attacks.
