## What it is
Valitron is a lightweight, standalone input validation library for PHP with zero dependencies. It provides a simple, fluent rule-based API for validating arrays of data such as $_POST input, with support for custom validation rules and dot-notation access to nested arrays.

## Use cases
- validate form input in php
- validate $_POST data before saving
- check required fields and email format in php
- validate nested arrays with dot syntax
- add custom validation rules without dependencies
- lightweight php validation library for small projects

## When to choose
- you need a dependency-free validation library for a PHP project
- you want simple, readable validation rules applied in a single call
- you are validating plain arrays like form submissions or JSON-decoded data
- you need to extend validation with custom callback rules

## When to avoid
- you need framework-integrated validation with ORM or request object support
- you require advanced features like conditional rule groups or schema-based validation
- your project already uses a full-featured framework validator like Laravel's or Symfony's
