PHP API Client Architecture (Native)

A lightweight API-driven application built using Native PHP.
This project aims to teach PHP without a framework, demonstrating a clear separation between:

• API Server – Handles database operations and returns JSON response
• Client App – Consumes API via cURL and renders data in HTML views

The goal is to understand and implement RESTful API architecture,
cURL-based HTTP requests, and modular MVC structure without frameworks.

🔥 Features

🖥 Client App

• MVC-like structure (Controller, Views, CurlClient)
• Consume API via cURL (GET, POST, PUT, DELETE)
• Modal-based CRUD (Create, Read, Update, Delete)
• Clean route handling (web.php?action=...)
• Redirect, form request handling, and dynamic response

🌐 API Server

• RESTful API in Native PHP
• JSON responses with HTTP status codes
• Endpoint-based structure (users/index.php, users/create.php, etc.)
• PDO-based database access
• Password hashing for secure user storage

⚙️ Installation & Setup

1️⃣ Clone the Repository

git clone https://github.com/your-username/php-api-client-architecture.git
cd php-api-client-architecture

2️⃣ Configure API

api-server/config/database.php

$host = "localhost";
$db_name = "your_database";
$username = "root";
$password = "";

3️⃣ Configure Client API URL

client-app/config/api_config.php

define("API_BASE_URL", "http://localhost/belajar-php-native/api-server/endpoints/");

4️⃣ Ensure cURL is enabled in php.ini

extension=curl

Restart Apache/Laragon after enabling.

🚀 Usage

Run API

http://localhost/belajar-php-native/api-server/endpoints/users/index.php

Run Client Application

http://localhost/belajar-php-native/client-app/

Auto loads UsersController@index
Displays users table with modal-based CRUD

🚧 Future Enhancements

• 🔐 Authentication with token-based login (JWT / OAuth)
• ⚠ Server-side validation and error handling
• 📄 Pagination and search
• 📁 File upload via API (image/avatar)
• ⚛ Migration to AJAX (Single Page API Client)
• 🧱 Refactor toward mini PHP MVC Framework
