I'm currently working on a PHP project and I'm having a bit of trouble with session variables. Specifically, I'm not sure how to unset a session variable in PHP. I've been using session variables to store user information, but there are certain cases where I need to clear out a specific variable.
I've tried searching online for a solution, but I haven't been able to find a clear answer. I've come across functions like `session_unset()` and `unset($_SESSION['variable'])`, but I'm not quite sure which one is the correct approach.
I would really appreciate it if someone could help guide me in the right direction. Could you please explain the proper way to unset a session variable in PHP? Are there any best practices or considerations I should keep in mind while doing this?
Thank you in advance for your assistance!
