Framework-agnostic PHP library for OpenSimulator grid management

⚠️ Important Notice

This is a pure PHP library – it does nothing by itself!

The OpenSimulator Engine provides core functionality for managing OpenSim grids, but requires a parent application to function. It handles database operations, configuration management, and OpenSim protocol communication, but provides no user interface or web endpoints.

📜 Project History

This library consolidates over a decade of OpenSimulator integration work that was previously scattered across multiple projects. While the dedicated engine repository is recent, the functionality has evolved through years of real-world usage in production OpenSim grids.

The code has been battle-tested across different implementations before being organized into this reusable, framework-agnostic library.

🎯 What This Library Does

✅ Database Operations – Robust/OpenSim database management
✅ OpenSim Protocol – REST API communication with grids
✅ Configuration Management – Grid and region settings management and storage
✅ Security Functions – Input validation and output escaping
✅ Form Generation – Dynamic configuration forms
✅ Installation – Process setup automation (initiated by parent)

🚫 What This Library Does NOT Do

❌ No web interface or HTML pages
❌ No user HTTP request handling
❌ No user authentication
❌ No WordPress or other CMS/framework dependencies
❌ No standalone application functionality

For Developers:

Use this engine to build your own OpenSim management applications
Integrate OpenSim functionality into existing PHP projects
Create custom grid administration tools

🚀 Quick Start for End Users

Don’t install this directly! Instead, choose a complete solution:

W4OS WordPress Plugin – Complete WordPress integration for OpenSim grids. Best for: Complete integration in a WordPress website.
OpenSim Helpers – Provides mainly helpers/ required by OpenSim grids to function properly, as well as minimal webui features. Best for: Separate helpers management, with minimal integration with the website.

🛠️ Developer Installation

As Composer Package

composer require magicoli/opensim-engine

As Git Submodule

git submodule add https://github.com/magicoli/opensim-engine.git engine

Usage in Code


// Bootstrap the engine
require_once 'engine/bootstrap.php';
// or require_once 'vendor/magicoli/opensim-engine/bootstrap.php' if installed via composer

// Engine provides the core classes and functions // See parent projects (W4OS, Helpers) for implementation examples

🤝 Contributing

This library follows strict architectural principles:

Framework-agnostic (no WordPress, no Laravel, etc.)
Pure data processing (no HTTP input/output)
Explicit data passing (no global variables)

See DEVELOPERS.md for complete guidelines.

Note: The library is undergoing architectural migration. API documentation and examples will be added once the refactoring is complete and the API is stable.
