php-sdk vs rust-sdk

php-sdk: The MCP PHP SDK is the official toolkit for implementing Model Context Protocol servers and clients in PHP. It offers a framework-agnostic API, allowing developers to expose PHP application functionality to AI agents or integrate with MCP servers.; rust-sdk: This is an official Rust SDK implementation for the Model Context Protocol (MCP), utilizing the Tokio async runtime. It enables developers to build and interact with AI agents by providing robust support for tools, resources, prompts, and advanced communication patterns.
