PHP Validation Libraries

This library is a PHP framework for enforcing data integrity and business rules by validating scalar values and complex object structures against predefined constraints. It provides a structured approach to inspecting object graphs and property metadata, ensuring that data conforms to expected requirements before it is processed by an application. The framework distinguishes itself through a metadata-driven mapping system that uses reflection or configuration files to apply rules directly to object properties. It supports contextual rule orchestration, allowing developers to organize constrai

Respect/Validation is a PHP validation library that operates on single input values through a fluent, chainable rule system. Each validator instance builds a linear constraint pipeline by appending rules to an internal stack, executing them sequentially and short-circuiting on the first failure. The library captures validation failures as structured exceptions, enabling callers to inspect detailed error metadata programmatically and respond with meaningful messages. The library distinguishes itself through its exception-based error handling model, which provides programmatic access to validat

This project is a PHP filesystem search component and file filtering library. It provides an object-oriented filesystem iterator designed to locate files and directories based on specific criteria. The library includes a project ignore file parser that allows the search process to respect version control exclusion patterns and metadata to skip unnecessary files. It covers a wide range of filtering capabilities, including the ability to isolate entries by name, path, size, and modification date. The tool also supports content-based filtering, type-based restrictions, and custom logic function

Eve is a REST API framework that maps database collections to web resources through declarative configuration files. It functions as a database-to-API mapper, automatically exposing data as RESTful endpoints with built-in support for CRUD operations and schema-based request validation. The project distinguishes itself through a HATEOAS API engine that generates hypermedia links and resource schemas for dynamic client discovery. It also includes an automated Swagger documentation generator that produces interactive specifications for client SDK generation and testing. The framework provides a
