This project provides a PHP port of the LangChain library, enabling PHP developers to build applications leveraging large language models (LLMs) through composability. It aims to bring LangChain's powerful natural language processing capabilities to the PHP ecosystem, allowing for the integration of LLMs with external data sources and computations.

How It Works

The library faithfully ports LangChain's core concepts and features into PHP, preserving familiar syntax and structure. It facilitates the creation of complex LLM-powered applications by enabling developers to chain together LLMs with other computational resources or knowledge bases, a key advantage for building sophisticated AI applications within a PHP environment.
