Object-Oriented PHP Part 3
CourseIn this series, we’ll continue to build the spaceship app that we’ve started in Introduction to Object-Oriented PHP and Object-Oriented PHP Part 2. In this tutorial, I’ll show you how to use the extends
keyword in PHP so that you can use it to inherit properties and methods from another class
.

In this tutorial, I will show you how to override a method that you’ve inherited from another class. By having two classes we are starting to shape the different behaviors and properties of each, while still keeping most things in common and not duplicated.
In this tutorial, I will show you the difference between public, private, and protected methods or properties in PHP classes. By the end of this lesson you will learn how to make things private at first, protected once you need to access them in a subclass, and public when you need to use it outside of its class and subclass.

In this tutorial, I will show you how to get around the problem of calling a function that you have overridden in your class: how to call the parent class method.

In this tutorial, I will show you how we can build a better blueprint and hierarchical structure for our app’s classes through the use of abstract classes.
Additional resources
In this tutorial, I will show you the power of abstract classes and how you can enforce subclasses to define certain functions. In this way, you can share logic but for things that are really specific to subclasses, you can force them to define certain functions, but with the specific logic required.

In this tutorial, I will show you how to extend an abstract class and ensure that all the methods that are required by the abstract class are included in this new class.

In this tutorial, I will show you how to handle new requirements for data storage by creating two smaller abstract classes out of our original data storage class. By creating these new abstract classes, we can build more flexibility into our code.

Now that we have created new abstract classes, we need to load and utilize them in our code. In this tutorial, I will show you how we can refactor our code to make use of our new abstract data loading classes.
We have an abstract class with methods that we require, but there’s no logic in these abstract methods. This is a perfect opportunity to use interfaces. In this tutorial, I will show you how to create and implement Interfaces. I will also explain how interfaces are useful when you will be sharing your code. But even if you’re not creating interfaces to share, chances are, if you’re using open source code — and definitely in Drupal — you will need to know how to implement interfaces.

TopicComposer is the preferred dependency management solution for PHP, is used by Drupal core, and is becoming increasingly popular for managing the modules and themes used for a Drupal project.
Drupal Console
TopicDrupal Console provides a command line utility for performing common site administration tasks, code generation scaffolding, and a Read-Evaluate-Print-Loop for interacting with your Drupal site.
Git
TopicThe Git version control system can help you keep track of changes in your codebase and make sure you don't unintentionally lose work.
Security
TopicKeeping a Drupal site secure requires monitoring security announcements, performing regular updates, and knowing how to properly use Drupal’s APIs to write secure code.
Drupal Composer Project
TopicThe Drupal Composer Project provides a scaffold for starting a new Drupal project and managing that project's dependencies with Composer. It was created before the drupal/recommended-project Composer project template was developed, which is the current best practice method for creating a new Drupal site with Composer.
