The Idea: Creating Blueprints for Objects

Before you write any code, you should understand what you are trying to achieve. In object-oriented programming, you use classes as blueprints to create objects. For example, if you want to represent cars in your code, you can define a class called Car.

Below, you define a simple Car class and then create an object from it.

CarExample.php

CarExample.php

copy
1234567891011
<?php // Define a simple Car class class Car { } // Create an object of the Car class $myCar = new Car(); // Output the object to show it exists var_dump($myCar);

The class Car {} line defines a new class named Car. The line $myCar = new Car(); creates an object (an instance) of the Car class and assigns it to the variable $myCar. This is the basic way to define a class and create an object in PHP.
