  Introduction The Data TransferObject (DTO) in PHP is a design pattern that allows you to transfer data between software application subsystems or layers in a structured way. DTOs are simple objects that typically contain fields to store data and may include methods for accessing and manipulating that data. They are used to encapsulate and transfer data between different parts of an application, helping to improve maintainability and reduce coupling between components.

  DTO vs. POPO DTO(Data Transfer Object) is used to transfer data between layers or systems. POPO (Plain Old PHP Object) is a simple PHP object without framework dependencies. DTOs are a specialized type of POPO, focused only on carrying data. DTOs typically have no business logic; POPOs might include behavior or methods. All DTOs are POPOs, but not all POPOs are DTOs.

  Why Use DTOs? DataSecurity: Prevents exposing sensitive fields (e.g., passwords, tokens). Decoupling: Separates internal models from external data consumers (like APIs). Data Consistency: Ensures only the required and validated data is transferred. Code Clarity: Makes code easier to understand and maintain by defining clear data structures. Testing Friendly: Simplifies unit testing since DTOs are predictable and contain no logic.

  When to Use DTOs? Youneed to move data between different parts of your app. Making sure data types match up and stay consistent is crucial. Keeping your code neat and easy to manage is a priority.
