How can the XAMPP development environment impact the functionality of PHP session variables?

When using XAMPP, the default session save path might not be set correctly, which can lead to issues with PHP session variables not being stored or retrieved properly. To solve this issue, you can manually set the session save path in your PHP configuration file (php.ini) to a writable directory.

// Set the session save path to a writable directory
session_save_path("C:/xampp/tmp");
