Meet the Class Blueprint
Lab: Introduction to PHP Object-Oriented Programming (OOP) for WordPress
Video Runtime: 04:53
The first step is to define our blueprint. In PHP, the keyword class
alerts PHP that this is a blueprint. The syntax is:
class Blueprint_Name { // define the blueprint in here }
An object is a noun, i.e. a thing. Therefore, its name should be a singular noun.
How you code the name varies depending upon if you are following PSR or the WordPress coding standard. Per PSR, class names should be in StudlyCaps, where the words are smooshed together and the first letter is capitalized. Per the WordPress Coding Standard, the words are separated by an underscore and the first letter of each word is capitalized.
The curly braces declare that the class has control over the code that is within them. That code is the blueprint that defines the characteristics and behavior.
Once upon a time, there was a developer... You! This is going to be a good story...
