## What it is
A PHP library and Stack middleware that implements the W3C CORS recommendation for http-foundation/http-kernel based applications. It can be used standalone as a CorsService or wrapped around an application as Stack middleware to handle preflight and actual CORS requests.

## Use cases
- add CORS headers to a PHP HTTP application
- handle preflight OPTIONS requests
- allow cross-origin API access from browsers
- configure allowed origins, methods, and headers for CORS
- enable credentialed cross-origin requests

## When to choose
- you run a Symfony, Laravel, or StackPHP-style PHP app needing CORS support
- you want a small, standards-compliant CORS implementation usable as library or middleware

## When to avoid
- your framework already ships a maintained CORS package you prefer
- you are not using http-foundation/http-kernel based request/response objects

## Facets
- artifact type: library
- maturity: stable
- function: middleware, http-server, security
- domain: web-development, backend, apis, security
- platform: php
- tags: cors, stackphp, http-foundation, http-kernel, cross-origin
