SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Backend architectures for PHP projects often suffer from unclear boundaries between controllers, services, and persistence layers, leading to tangled code, fragile maintenance, and inconsistent transaction handling.

Core Features & Use Cases

Establish clear separation between Controller, Service/Handler, and Repository layers to improve testability and maintainability.
Provide guidance on data access patterns, transactions, caching, and background jobs to improve performance and reliability across Yii2, Laravel, and Symfony.
Assist during refactors or new module design to minimize architectural drift and enforce consistent error translation.

Quick Start

Begin by mapping existing controllers to services and repositories and enforce explicit transaction boundaries to ensure predictable state changes.

FAQPage Schema

How do I separate controller, service, and repository layers in PHP backends?▼

Separate PHP backend layers by enforcing clear boundaries between transport, business logic, and persistence. This structure isolates controllers from data access, improving maintainability and testability across Yii2, Laravel, and Symfony projects.

What is the best way to handle database transactions and error translation during PHP module refactoring?▼

Database transaction handling requires explicit transaction scopes at service boundaries. By translating exceptions at these boundaries during PHP module refactoring, you ensure predictable state changes and enforce consistent error handling across data access layers.

Does this backend architecture pattern work with Laravel, Symfony, and Yii2 frameworks?▼

This backend architecture pattern works with Laravel, Symfony, and Yii2 frameworks. It applies consistent design boundaries across these PHP platforms to improve testability, minimize architectural drift, and maintain reliable data access.

How do I map existing controllers to services and repositories to reduce architectural drift?▼

Map existing controllers to services and repositories by evaluating current dependencies and enforcing explicit transaction boundaries. This process isolates business logic from transport layers, yielding predictable state changes and reducing architectural drift.

Why does tangled PHP backend code cause fragile maintenance and inconsistent transaction handling?▼

Tangled PHP backend code causes fragile maintenance because unclear boundaries between controllers and persistence layers mix transport and business logic. This lack of separation leads to inconsistent transaction handling and fragile state changes during updates.
