REST API in PHP 7.4

A compact REST API built without a framework to demonstrate routing, authentication, validation, repositories, services, PDO and JSON responses directly in PHP.

This is an older project and I keep it public as part of my backend engineering history.

What it demonstrates

• PHP 7.4
• Object-oriented PHP
• Manual autoloading
• Namespaces
• PDO
• MySQL
• Repository and service separation
• Request validation
• Bearer authentication
• JSON responses
• GET, POST, PUT and DELETE endpoints

Structure

bootstrap.php
autoload.php
index.php
script_banco.sql

Routes

GET    /usuarios/listar
GET    /usuarios/listar/{id}
POST   /usuarios/cadastrar
PUT    /usuarios/atualizar/{id}
DELETE /usuarios/deletar/{id}

Local setup

1. Create a MySQL database named webservice.
2. Import script_banco.sql.
3. Configure the database values in bootstrap.php.
4. Serve the project with Apache or another environment compatible with the included .htaccess.

Historical context

This project intentionally remains close to the way I originally built it. It is not meant to represent my current preferred architecture or PHP version.

Its value in the portfolio is showing direct experience with lower-level PHP web-service concepts without relying on a framework.
