Bug #44352 mysqli_connect_error() false negative for host errors From now on the mysqli object doesn't have that magic properties, like error, which were readable but not visible through isset(), property_exists() and var_dump(). All other ext/mysqli classes were fixed too. Now it will be easier to debug mysqli based applications.
