Class abstraction – PHP

In PHP, class abstraction refers to the ability to define abstract classes that cannot be instantiated directly, but can only be inherited by other classes. Abstract classes serve as templates for concrete classes that extend them, providing a common interface and implementation for a group of related classes.

An abstract class is defined using the “abstract” keyword in PHP and can contain both abstract and non-abstract methods. Abstract methods are defined without any implementation and must be overridden by concrete subclasses. Non-abstract methods can have an implementation and can also be overridden by subclasses.

By using class abstraction in PHP, you can create more organized and modular code, making it easier to maintain and update. It also enables you to define a common set of methods and properties that can be shared among multiple classes, reducing redundancy and improving code reusability.
