How to set up autocompletion in PhpStorm?

Question

PHP

// Тут создаю экземпляр класса
$Mango = new Mango($DataBase);

// пытаюсь использовать один из методов класса
$Mango->

And instead of a list of class methods, I see "no suggestion". And if you click on Mango with the control, it opens the file with the class. Tried doing "Invalidate Caches" - didn't help.

Answer 1

Are you sure you are opening a project and not a separate file?
Everything should work right away.
