What is the static data type?

Question

Yii

I'm reading the Yii2 API, namely the description of the ActiForm::begin() method, and I see that static is written in the return field. Is it a pseudo type? or what? In fact, the method objects to the form object.

Answer 1

This is the class at the top of the inheritance hierarchy from which the method is called. Self and Static can be put in the same row. Self is the class in which this method is written, and static is the class from which the method is called. It may be the same class, or it may be a successor. Read about late static binding .
