Also an abstract class cant directly create an object by the class.

Use of abstract class in php. Use of abstract classes are that all base classes implementing this class should give implementation of abstract methods declared in parent class. Thus we cannot create objects out of abstract classes. The abstract class compulsorily contains one method as abstract. Instead we need to create child classes that add the code into the bodies of the methods and use these child classes to create objects.

Use an abstract class to define a common base class for a family of types. Abstract class in php a class that has at least one method which is a method without any actual code in it just the name and the parameters and that has been marked as abstract is known as an abstract class. Unlike c abstract classes in php are declared with the help of abstract keyword. Php makes a way for the parent class to be more specific by making the use of abstract class and abstract methods.

Use an abstract class to provide default behavior. Subclass only a base class in a hierarchy to which the class logically belongs. Using an abstract class you can define behaviour while marking the class itself as incomplete. When we want to define an abstract class we need to use the keyword abstract.

When inheriting from an abstract class all methods marked abstract in the parents class declaration must be defined by the child. An abstract class is defined using the abstract keyword and abstract is a type of class. This comes in very handy. Also this abstract class can have other non abstract methods as well.

Methods defined as abstract simply declare the methods signature they cannot define the implementation. An object cant be created as an abstract class using the new keyword. Php 5 introduces abstract classes and methods. Classes defined as abstract cannot be instantiated and any class that contains at least one abstract method must also be abstract.

An abstract class can contain abstract as well as non abstract methods. Abstract methods can only have names and arguments and no other code. An abstract class is a class that has at least one abstract method. Abstract classes are the classes in which at least one method is abstract.

And an abstract class is something like an interface in php.
