What are the potential pitfalls of using session_write_close() in Zend Framework?

Using session_write_close() in Zend Framework can potentially cause issues with session data not being properly saved if there are still session variables being accessed after the call to session_write_close(). To avoid this pitfall, make sure to close the session only after all necessary session data has been read or written.

// Save session data before closing the session
$_SESSION['example_data'] = 'example_value';

// Close the session after all necessary data has been read or written
session_write_close();
