is session_unset() the correct way to clear and reset PHP Sessions variables?

Hey there,

I've used PHP sessions extensively in my projects, and while "session_unset()" can clear session variables, it might not be the best approach. Let me explain why.

`session_unset()` only removes the values stored in the session variables. It doesn't destroy the entire session itself. The session data and session ID will still persist until the session is officially destroyed. So, if you're looking to completely clear and reset the session, you might want to consider using `session_destroy()` instead.

The `session_destroy()` function destroys all session data associated with the current session and removes the session file from the server. It effectively terminates the session and starts a new one. To ensure proper removal of session data, it's always a good practice to call `session_destroy()` followed by `session_start()` to initiate a fresh session.

Here's an example of how you can clear and reset session variables using `session_destroy()`:

session_start();

session_destroy();

session_start();

Hey!

I understand the need to clear and reset PHP session variables. While using `session_unset()` can indeed clear the variables, there is another approach that I find more effective based on my personal experience.

Instead of solely relying on `session_unset()`, I prefer to use a combination of `session_unset()` and `session_regenerate_id()`. Let me explain why.

First, I use `session_unset()` to clear the session variables, ensuring that no residual data remains. However, it's important to note that the session ID itself remains the same.

To address that, I follow it up with `session_regenerate_id()`. This function generates a new session ID and replaces the existing one. This is crucial from a security standpoint as it helps prevent session fixation attacks.

Here is an example of how you can clear and reset session variables using these two functions:

session_start();

session_unset();

session_regenerate_id(true);
