psr15-chain-request-handler

Introduction

A PSR-15 compatible chain request handler for PHP. This package allows you to combine multiple request handlers in a chain, processing HTTP requests sequentially until a handler returns a non-404 response. If all handlers return 404, a final 404 response is returned.

Features

• Chain multiple PSR-15 request handlers
• Automatically skips handlers that return 404
• Simple API for adding handlers dynamically
• Fully PSR-15 compatible
• Well-tested and easy to integrate
