PHP Mastery Object-Oriented Design & Test-Driven Development

In this lecture we start by examining the basic structure of a PHP class, create a class with properties and behaviors, create an object and use it.

Now that you know how to create and instantiate a class, you can learn how to initialize an object using a constructor.

Encapsulation refers to protecting the internals of an object from direct manipulation by the client. The client can send messages, but the client cannot directly change the properties in the object. Lets see how to encapsulate an object in PHP.

Inheritance is the ability for a subclass to inherits all of the public and protected methods and properties from the parent class.

Declaring class properties or methods as static makes them accessible without needing an instantiation of the class. Let talk about Static Methods & Properties and learn how to use them in PHP.

With Object-oriented programming, the possibilities are endless, let's now consider a new concept in OOP called method chaining.

In this lecture you will learn both theoretical and practical implementation of abstract classes in PHP using a simple case study

In this lecture, you will learn both the theoretical and practical implementation of abstract classes in PHP using a simple case study.

In this lecture, you will learn about object interfaces in PHP, why they are important, why you should use them, and also how to use interfaces using a simple case study.

Let's talk more about late static binding and fix a bug from the last lecture using late static binding.

Let's now discuss about namespaces and autoloading in PHP as these are two very important aspects when building model applications

In this video I'll go over the requirements for the simple grading class that we are going to build

Lets build the class to compute result for 5 subjects in a semester

Time to tie everything together by linking the grading class to the form and outputting relevant data to the UI
