Example of using Late Static Binding in PHP.
Article Introduction：Delayed static binding in PHP: flexible database queries
Lazy static binding (LSB) is a feature in PHP that allows a subclass to reference a static property or method of its parent class using the static keyword.

The value ultimately comes from the class that calls the function.
Application scenario: dynamic database query
