Core Laravel Package

Product Decisions This Supports

• High-Performance APIs/Microservices: Justify investment in a PHP-based async I/O framework to replace Node.js/Python for latency-sensitive workloads (e.g., real-time analytics, gaming backends, or trading systems).
• Roadmap for Scalability: Enable horizontal scaling of PHP applications without rewriting core logic (e.g., transitioning from synchronous Laravel to async event-driven architecture).
• Build vs. Buy: Avoid building a custom async PHP solution (high dev cost) when OpenSwoole’s core provides battle-tested primitives (coroutines, reactors, TCP/UDP).
• Use Cases:
  • WebSockets: Replace Pusher/Socket.io for custom real-time features (e.g., live collaboration tools, chat apps).
  • High-Concurrency APIs: Serve 10K+ concurrent requests with low resource usage (vs. traditional PHP-FPM).
  • Hybrid Architectures: Integrate with Laravel’s request lifecycle while offloading async tasks (e.g., background jobs, WebSocket handlers).
  • Legacy Modernization: Extend monolithic PHP apps with async capabilities without full rewrite.

When to Consider This Package

Adopt if:

• Your PHP stack (Laravel/Symfony) is a bottleneck for I/O-bound workloads (e.g., high request volume, WebSockets, or external API polling).
• You need sub-millisecond latency for real-time features and PHP’s synchronous model is prohibitive.
• Your team has PHP experience but lacks Node.js/Python async expertise (lower learning curve than rewriting in Go/Rust).
• You’re building serverless-like PHP functions (e.g., AWS Lambda equivalents with async execution).
• Open-source licensing aligns with your project (MIT-like permissive terms).

Look elsewhere if:

• Your workload is CPU-bound (OpenSwoole excels at I/O, not parallel compute; consider Rayon for PHP or Go/Rust).
• You need managed services (e.g., AWS App Runner, Heroku) that don’t support OpenSwoole’s coroutines.
• Your team lacks C/PHP extension experience (OpenSwoole requires PECL or Docker setup).
• You’re constrained by vendor lock-in (e.g., Laravel’s ecosystem may not fully support OpenSwoole’s async patterns yet).
• Alternatives (e.g., RoadRunner, Swoole’s PHP wrapper) offer better Laravel integration or commercial support.

How to Pitch It (Stakeholders)

For Executives: "OpenSwoole lets us keep PHP/Laravel for our proven stack while unlocking Node.js-level performance for real-time features—cutting cloud costs by 60% for high-concurrency APIs. For example, a WebSocket chat app could handle 10K users on a single server instead of 1K. It’s a low-risk bet: we reuse our PHP team’s skills, avoid rewriting in Go, and future-proof for async Laravel (already in development). Pilot with our [highest-latency service] to prove ROI in 3 months."

For Engineering: *"OpenSwoole gives us coroutines (like Go’s goroutines) and a reactor model natively in PHP. Key wins:

• Drop-in async: Replace sleep() with Swoole\Coroutine::sleep() for non-blocking I/O.
• Laravel-friendly: Use it alongside Laravel’s request lifecycle (e.g., offload WebSocket logic to a coroutine).
• Tooling: Works with Laravel’s service container, queues, and even Horizon for async jobs. Tradeoff: Requires PECL or Docker setup, but we can start with a micro-service (e.g., WebSocket gateway) to validate before full adoption. Alternatives like RoadRunner are higher-level but less flexible long-term."*
