PHP 8.0 has a new feature that automatically promotes class constructor parameters to corresponding class properties with the same name if the constructor parameters are declared with a visibility modifier and are not of type. The new feature adds support for enumerations, or enums, to declare an enumerated set of values that are similar to class objects.
