How to create a similar structure Class1::$app->class2->method()?

Question

PHP

In Yii, you can call other classes and their methods through the main class. For example, Yii::$app->security->getRandomString(). And how is it possible to create such a structure? Or is there a common name for something like this?

Answer 1

Yii::$app is a static class property. In fact, something like a singleton. Total - anti-pattern.
