How can session data be managed effectively in PHP scripts to avoid conflicts?

Session data can be managed effectively in PHP scripts to avoid conflicts by using session locking. This ensures that only one script can access the session data at a time, preventing conflicts when multiple scripts try to read or write to the session simultaneously. 

session_start();

// Lock the session data to prevent conflicts
session_write_close();

// Access and modify session data
$_SESSION['user_id'] = 123;

// Reopen the session for further modifications
session_start();

// Continue working with session data
$_SESSION['username'] = 'john_doe';
