Today i get strange thing for my phpstorm 8. Usually its hinting anything, but since today when i try to instantiate some class its noting show up. Except custom class i made during the work. Example if i want start mysqli connection, i type $var = new my... usually this will showing mysqli & co. But its gone now, i trying to fix this by go to setting > language and frameworks > php and change the setting there but still no luck. Any idea for this?
