What are some common pitfalls in managing PHP sessions that could lead to session loss?

One common pitfall in managing PHP sessions that could lead to session loss is not properly setting the session save path. If the save path is not set or is not accessible by the web server, the session data may not be saved correctly, leading to session loss. To solve this issue, make sure to set the session save path to a writable directory on your server.

// Set the session save path to a writable directory
session_save_path('/path/to/writable/directory');
