README

Attribute-based validation for PHP 8.4+ : validate method parameters, return values and property access using compact, reusable attributes

Validator - Declarative validation using PHP 8+ attributes

A lightweight, framework-agnostic library that lets you declare validation rules as PHP attributes. Validate method parameters, method return values, and property get/set using compact, reusable attribute classes ( for example #[Range], #[Pattern], #[Vector] ) Built-in caching of reflection metadata keeps runtime overhead low

📦 Installation

Install via Composer :

composer require taknone/attributes

Then enable Composer autoload in your project :

require_once __DIR__.'/vendor/autoload.php';

🚀 Quickstart

The repository includes an examples directory with runnable examples and small helper scripts

Contributing

PRs welcome ! Follow a few rules :

1. Run and add example for new validators
2. Keep attribute constructor arguments constant expressions ( required by PHP attributes )
3. Document behavior for corner cases ( nullability, casting, unique semantics )
