  • Can we create object of abstract class in PHP?

    PHP has 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.
    Methods defined as abstract simply declare the method's signature; they cannot define the implementation.

  • How many objects of abstract class can be?

    Solution: The answer to the question of how many instances of an abstract class can be created is zero.
    That is, we cannot create an instance of an abstract class as it does not have any complete implementation.
    An abstract class acts like a template or an empty structure.

  • Can abstract classes have objects?

    You can't create an object of an abstract class type.
    However, you can use pointers and references to abstract class types.
    You create an abstract class by declaring at least one pure virtual member function.
    That's a virtual function declared by using the pure specifier ( = 0 ) syntax.

  • An abstract class is like the normal class it contains variables it contains protected variables functions it contains constructor only one thing is different it contains abstract method.
    Abstract must contains the abstract method and those methods must be defined in its inheriting class.

An abstract class is a class that has at least one abstract method. Abstract methods can only have names and arguments, and no other code. Thus, we cannot create objects out of abstract classes.
