100site — Multi-Site CMS (PHP-Fusion Modification)

100site is a lightweight multi-site content management system developed in 2015 based on PHP-Fusion. It enables managing multiple websites using a single codebase, with each site connected to a separate database depending on the domain.

🧩 What is PHP-Fusion?

PHP-Fusion is an open-source lightweight CMS written in PHP. This project is a modification (fork) of the original PHP-Fusion system, enhanced with multi-site support to allow running multiple websites from the same script.

🔁 Features

• Multi-site architecture: Manage multiple websites using one codebase.
• Domain-based DB routing: Automatically switches database based on the domain name.
• Preserves PHP-Fusion’s core: All original modules, admin panel, and CMS features remain intact.
• Separate content and configuration: Each site stores its own settings and content in its individual database.

---

🏗 Project Structure Overview

The structure mostly follows the standard PHP-Fusion layout with added routing logic for dynamic database switching based on domain.

Key Files:

• maincore.php – PHP-Fusion's main core file.
• config.php – Uses router output to establish DB connection.
• index.php – Entry point of the CMS.
• administration/ – Standard PHP-Fusion admin panel.

⚙️ Installation Guide

1. Upload the project

Upload all files to your web hosting or VPS server.

2. Configure domain-based DB routing

Edit the config/config_router.php file like this:

if ($_SERVER['HTTP_HOST']=="100site.loc") {
	// database settings
	$db_host = "localhost";
	$db_user = "root";
	$db_pass = "";
	$db_name = "100site";
	$db_prefix = "c2y_";
	define("DB_PREFIX", "c2y_");
	define("COOKIE_PREFIX", "mz4_");
	define("SITE", "site1");
	define("ROBOTS", "Disallow");
}


3. Create databases

Use the official fusion.sql from PHP-Fusion to initialize each site’s database. This will create necessary tables such as site_settings, users, news, etc.

4. Configure domains

Each domain (or subdomain) should point to the root directory where the script is hosted.

⸻

👨‍💻 Admin and User Panel

The classic PHP-Fusion admin panel is fully functional per site. Each website connects to its own database and has independent content, users, and settings.

⸻

📌 Use Cases
	•	Web studios managing multiple client sites from one CMS instance.
	•	Regional versions of a single website.
	•	Lightweight multi-site setups on shared hosting environments.

⸻

🛡 Security Notes
	•	Add config.php to .gitignore to avoid exposing DB credentials.
	•	Ensure your server supports PHP 7.x or higher.
	•	It is recommended to migrate to PDO for secure DB connections in the future.
