What is types of inheritance in php?

Question

Accepted Answer

There are three types of inheritance in PHP: single, multiple, and multilevel.

Single inheritance involves a child class inheriting from a single parent class.
Multiple inheritance involves a child class inheriting from multiple parent classes.
Multilevel inheritance involves a child class inheriting from a parent class, which in turn inherits from another parent class.
PHP only supports single inheritance natively, but multiple inheritance can be achieved using interfaces.
Example: class ChildClass extends ParentClass { ... }
Example: class ChildClass extends ParentClass1, ParentClass2 { ... }
Example: class ChildClass extends ParentClass { ... } class ParentClass extends GrandparentClass { ... }
Example: interface Interface1 { ... } interface Interface2 { ... } class ChildClass implements Interface1, Interface2 { ... }
