Secure Polyglot Notes API (PHP Layer)

A lightweight, high-performance, and secure native RESTful Notes API built using Modern PHP (Native PDO) and backed by a PostgreSQL database running inside a Docker container.

This project implements strict user isolation via JWT Authentication using a Front Controller routing architecture.

Features

• Zero Heavy Frameworks: Built using pure, modern native PHP.
• Front Controller Architecture: All requests are funneled through a single routing engine (index.php).
• JWT Authentication: User validation and secure stateless token signatures via firebase/php-jwt.
• Data Isolation: Database parameters strictly query user IDs to prevent cross-account leaks.
