Show HN: phpClaw – AI agent runtime for PHP with tools, memory and guards

phpClaw is an AI agent runtime for PHP that provides built-in tools, memory management, security guards, and a ReAct loop without framework dependencies or vendor lock-in. It supports multiple LLM providers (Anthropic, OpenAI, Groq, Gemini, etc.) and allows developers to quickly create AI agents with capabilities like shell commands, HTTP requests, database queries, and code search through a simple builder pattern. The framework emphasizes security with prompt injection defenses and memory abstraction, distinguishing itself from basic LLM SDKs by providing a complete agent runtime rather than just an API client.
