Creating an Object
Lab: Introduction to PHP Object-Oriented Programming (OOP) for WordPress
Video Runtime: 07:57
The class is the blueprint. Then how do we make an object from it? You use the new
keyword. Think about that. If you wanted to build a house, the architect gives the blueprints to the craftsmen. They will build you a new house. The house is the object, built off the blueprint. Got it?! Do you see how new makes sense?
In this episode, you will create your first object from the blueprint you built in the last episode. You are creating a new user.
New terms that you will learn are:
- Instance – meaning the object, i.e. it’s an instance of the blueprint
- Instantiate – it’s the process of creating the object
You’ll also learn more about PHP Namespacing too, as you see I’m using it not here in this lab, but virtually every lab on Know the Code.
Don’t repeat yourself. Don’t repeat yourself. Don’t repeat yourself.
