SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PHP codebases often lag behind PHP 8.x features, leading to maintainability and safety issues. This skill helps teams modernize by adopting constructor property promotion, unions, enums, readonly classes, and improved static analysis readiness.

Core Features & Use Cases

  • Constructor Property Promotion: Simplifies class construction by declaring properties in the constructor.
  • Readonly Classes and Enums: Enables immutable data structures and fixed value sets.
  • Match Expressions & Named Arguments: Improves readability and clarity of control flow.
  • DTOs and Value Objects: Replaces arrays with structured data types for safer APIs.
  • Static Analysis Guidance: Aligns with PHPStan, Rector, PHPat, and PHP-CS-Fixer to enforce quality.

Quick Start

Audit your codebase for PHP version compatibility and implement constructor property promotion where possible to begin modernization.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I modernize PHP code to use constructor property promotion and readonly classes?

Modernize PHP code by applying constructor property promotion to declare properties directly in constructors, and converting data structures to readonly classes. This simplifies class construction and enforces safer type usage in PHP 8.2-8.4 projects.

What is the best way to replace arrays with DTOs and value objects in PHP 8?

Replace arrays with Data Transfer Objects and Value Objects to create structured data types for safer APIs. This modernization leverages PHP 8.x features like enums and unions to enforce type safety and reduce runtime errors.

Can I use PHPStan and Rector for automated PHP 8 code modernization?

Yes, PHPStan and Rector are supported for PHP 8 code modernization. PHPStan provides static analysis readiness, while Rector automates code upgrades. Additional guidance covers PHPat and PHP-CS-Fixer to enforce quality and apply modern patterns.

Does upgrading to PHP 8.4 require match expressions and named arguments?

Upgrading to PHP 8.4 does not strictly require match expressions and named arguments, but adopting them improves readability and control flow clarity. Modernizing PHP apps involves applying these features alongside enums and unions for safer, faster upgrades.

When should I not use readonly classes during PHP code modernization?

Avoid using readonly classes during PHP code modernization when your data structures require mutability after instantiation. Readonly classes enforce immutability, so if your application logic relies on modifying object state post-creation, this pattern is unsuitable.
