Answer by OZ_ for How do I make my PHP IDE understand Dependency Injection Containers?

You can define class of the variable 'manually':

/** @var YourClassType $mailer */$mailer = $container['mailer'];

In PhpStorm (and by standards), use two asterisks and write the data type before the name of the variable.

You can write the data type without the name of the variable (but not the name without the data type).
