Class Static
Lab: Introduction to PHP Object-Oriented Programming (OOP) for WordPress
Video Runtime: 17:49
In PHP, a class can have static properties and methods. A static is bound to the class blueprint and not the object or any of the objects. Therefore, all of the objects share the static code. If the class has a static property, then any object that changes that property is reflected and changed for every single object of that class.
This is a very important episode. Make sure you watch it at least once. This episode will help you to cement the different of statics and objects.
You access the static with a double colon ::. Within the class, you can use either the class name or the keyword self, as self is a placeholder for the fully qualified class name. External to the class, you use the class name.
How can you access the static from an object? How is a static different from the internals of an object? Learn more by signing in or Go Pro.
If you listen carefully, you can hear the 1s and 0s flowing in your computer.
