Does this skill require specific external tools?

Yes, it is designed to work alongside PHPStan (level 9+), Rector, PHPat, and PHP-CS-Fixer to ensure code quality and automated migration.

Can it help with Symfony-specific modernization?

Yes, it includes specific patterns for Symfony architecture, including Dependency Injection (DI) patterns, PHP-based configuration, and PSR-14 event handling.

How does it handle unstructured data like associative arrays?

The skill identifies structured data stored in arrays and recommends refactoring them into typed DTOs or Value Objects to improve IDE support and static analysis.

What versions of PHP does this skill support?

It supports all modern versions from PHP 8.0 up to PHP 8.5, including features like constructor promotion, enums, match expressions, and readonly classes.

What is the minimum recommended PHPStan level?

The skill requires a minimum of PHPStan level 9 to enforce strict mixed type handling, though level 10 is recommended for maximum safety.

API開発

Upgrades legacy PHP applications to PHP 8.x standards using automated refactoring, strict type safety, and static analysis.

概要

The PHP Modernization skill transforms aging PHP codebases into high-performance, type-safe applications by leveraging modern features from PHP 8.0 through 8.5. It enforces strict architectural standards through PHPStan level 10, PSR/PER compliance, and the replacement of legacy arrays with typed DTOs and Value Objects. By integrating automated refactoring with Rector and architecture testing with PHPat, it ensures that your application remains maintainable, secure, and perfectly aligned with current industry best practices.
