Data Mapper Design Pattern in PHP

• It transfers the data between persistent layer and in memory layer.
• It keeps the in memory layer and the persistent data layer independent of each other.

Persistance Layers

• Json place holder api
• Base url: https://jsonplaceholder.typicode.com
• Sample data: https://jsonplaceholder.typicode.com/users/1

In memory Layers

User {
    getId
    getEmail
}

Mapper

We will implement UserMapper class in order to map external api data in to User class and vise versa.
