Ever needed to share logic between two php classes without extending another class? Introducing php traits! 🤩

Let's say you have the following classes that don't share a common base class.

class Product {
    public function getPrice() {
        return $this->price / 100;
    }
}

class Order {
    public function getPrice() {
        return $this->price / 100;
    }
}

As you can see they share some portion of logic. So how to extract that when they don't share a common class? 🤔

Easy: Use a trait! 😁

trait HasPrice {
    public function getPrice() {
        return $this->price / 100;
    }
}

class Product {
    use HasPrice;
}

class Order {
    use HasPrice;
}

And that's it! You successfully extracted the shared logic without extending a class. Awesome, right? 😊
