What's the best way to validate data in both controllers and models, before creating/reading/updating/deleting this data

Maybe with a multidimensional session array:

Code:

session_start();

$_SESSION['errors']['controller'][] = 'error caught in the controller';

$_SESSION['errors']['model'][] = 'error caught in the model';
