What is the primary difference between session data and flashdata in CodeIgniter?
- Flashdata is only available during the next server request and is then automatically cleared.
- Flashdata is stored in cookies, while session data is not.
- Session data is only used for flash messages and not other data.
- Session data persists throughout the user's entire session.
The primary difference between session data and flashdata in CodeIgniter lies in their lifespan. Session data persists throughout the user's entire session, while flashdata is only available during the next server request and is automatically cleared afterward. Flashdata is useful for temporary messages or data that needs to be displayed once, such as flash messages, while session data is suitable for information that should persist across multiple requests during a user's session. Understanding this difference is crucial for effective use of session-related features in CodeIgniter.
