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 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.
