Explanations for yii2?
Tell me, please, what is this and do I understand correctly?
PS I'm familiar with OOP, I'm studying in detail.
Here in yii2 Yii::$app->session->setFlash
Yii::$app - here, as I understand it:
Yii is a (namespace) abbreviated name where to refer to the Yii class.
Next, :: this is what we are accessing the $app property of the Yii class.
But further it is not clear, -> is this a call to the method (as far as I understand) in which we turn to the setFlash method?
