24Example Explained
25The Strawberry class is inherited from the Fruit class.
26
27This means that the Strawberry class can use the public $name and $color properties as well as the public __construct() and intro() methods from the Fruit class because of inheritance.
28
29The Strawberry class also has its own method: message().
