What is an abstract class in PHP?

How can it be used?

Solution

  • An abstract class is a class that contains at least one abstract method, which is a method without any actual code in it, just the name and the parameters, and that has been marked as "abstract".

    The purpose of this is to provide a kind of template to inherit from and to force the inheriting class to implement the abstract methods.

    An abstract class thus is something between a regular class and a pure interface. Also interfaces are a special case of abstract classes where ALL methods are abstract.

    See this section of the PHP manual for further reference.
