OOP/PHP - What is the best pattern when you have multiple objects with shared relations?

Let's imagine i have these models:

• Classified
• Mobile phone
• Computer;
• Etc...

The classified has some generic attributes like (title, price, and so on). And Mobile phone has specific attributes like Computer and other models.

Since i have to implement some controllers to create a REST api i'm thinking on:

• MobilePhoneListController;
• MobilePhoneSinglePageController;
• ComputerListController;
• ComputerSinglePageController;
• ClassifiedTrait (for shared operations).

But there are any kind of pattern which fits better on a situation like this one?
