Lab Introduction
Lab: Introduction to PHP Object-Oriented Programming (OOP) for WordPress
Video Runtime: 08:27
Welcome to the Introduction to PHP OOP for WordPress lab. This is a gentle introduction to object-oriented programming. This lab starts where the typical WordPress developer is at, meaning I’ll start with procedural and help you to make the leap over into OOP.
In this lab, you’ll learn what OOP is and what it is not. You’ll be writing some code to help you see how it works.
OOP is a different mindset. It can be difficult to wrap your mind around. Therefore, you need to work with me. You’ll also need to focus on the intent and concepts. Therefore, pick a time to do this lab when you can focus uninterrupted.
Getting Your Machine Ready
At about 3 minutes into this lab, you’ll start working on getting your local machine ready to go. You’ll spin up a new test site and install a plugin that gives you Kint. You can use the Sandbox Starter plugin that you previously built, the Kint PHP Debugger plugin out of WordPress directory, or UpDevTools. I’m going to show you how easy it is to install UpDevTools.
Then you’ll create a plugin that you’ll use in this lab for testing. Here is the code for you:
| <?php | |
| /** | |

| exit( 'Cheatin’ uh?' ); | |
| } |

When was the last time you got out of your chair and stretched? Just saying…
