What does php class object mean?

Class − Defines the abstract characteristics of a thing. The definition of a class includes the form of the data and the operations on the data.

Object − is an instance of a class.

In object-oriented programming (English: Object-oriented programming, abbreviation: OOP), an object is a whole composed of information and a description of how to process the information, and is an abstraction of the real world.

In the real world, the things we face are objects, such as computers, televisions, bicycles, etc.

The main three characteristics of the object:

The behavior of the object: what operations can be applied to the object, turning on the light and turning off the light are behaviors.

The shape of the object: how the object responds, color, size, and appearance when those methods are applied.

Representation of objects: The representation of objects is equivalent to an ID card. It specifically distinguishes the differences between the same behaviors and states.

For example, Animal is an abstract class. We can specify a dog and a sheep, and dogs and sheep are concrete objects. They have color attributes, can be written, can run and other behavioral states. .
