hi people,i want to know the difference between implementing abstract and extending an object(object inheritance) in php !according to what i know implementing abstract is using all code of parent class, and extending an object is also same including you can override a method...so if we have inheritance(i.e. extending an object) then why to use abstract ?

Abstract objects and inheritance aren't mutually exclusive.

 

Inheritance is when a class extends from another one. An abstract class is just a class that doesn't represent any particular object you're going to create.

 

An example of abstract class would be Vehicle. You extend Car and Bike from Vehicle, but you never create a new Vehicle.
