In the previous exercise, we asked you to imagine a class for pets. Let’s see how we would actually create a PHP Pet class.

To define a Pet class, we use the class keyword followed by the class name (typically title cased in PHP) and curly brackets:

class Pet {

}

Within the curly brackets, we can add properties, which define the data each object of the class will contain. The syntax is similar to how we define variables:

class Pet {
  public $name, $color;
}

Note: The public keyword has to do with something called visibility. We’ll discuss this in depth later in the lesson.
