MonkeysLegion Validation
========================

[](#monkeyslegionvalidation)

Attribute‑driven **DTO binding & validation layer** for the [MonkeysLegion](https://github.com/monkeyscloud) PHP framework.

---

✨ Features
----------

[](#features)

- **Attribute‑based constraints** – ship with `#[NotBlank]`, `#[Email]`, `#[Length]` (extend in minutes)
- **Automatic binding** – JSON body *and* query parameters → strongly‑typed DTO
- **PSR‑15 middleware** – intercepts the request, validates, and returns a *400 JSON* error payload if needed
- **Fail‑fast & zero‑magic** – no doctrine/metadata proxies, only native PHP reflection
- **Extensible** – write a new constraint attribute in <10 LOC
- **Lean footprint** – depends only on PSR interfaces + Laminas Diactoros for JsonResponse

---
