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
