PHP Classes/Objects

This lesson is part of PHP · All levels

Summary

A class is a blueprint that defines a property as data and a method as behavior, whereas an object is a real instance made of that class. In PHP you create an object with the new keyword, then access its members using the -> sign. With OOP, code becomes more organized, reusable, and easier to maintain as the project grows.

Key points

Class describes structure and behavior, objects are the result of an instance of a class.
The data-storage property and the method running the action, both of which are accessed via the -> sign.
The new keyword is used to make an object from a class.
$this refers to an object running so that the method can access its own properties.
