Instructor for PHP
A PHP library for structured data extraction from LLMs, unified LLM API access, and building AI agents.
What is Instructor for PHP?
Instructor for PHP is a framework-agnostic toolkit that simplifies integrating Large Language Models (LLMs) into PHP applications. It provides a unified API for over 20 LLM providers and enables developers to extract strongly-typed, validated data from LLM outputs without writing boilerplate parsing code. The library transforms messy model outputs into typed PHP objects, arrays, or enums using simple class definitions.
PHP developers building applications that require structured data extraction from LLMs, such as those working on AI agents, data processing pipelines, or any system needing validated outputs from language models. It is particularly useful for teams using Laravel or Symfony, as it offers first-party framework integrations.
Developers choose Instructor for PHP because it eliminates the need to manually parse and validate LLM JSON responses, reducing boilerplate and errors. Its unique selling point is the combination of a unified API for multiple LLM providers with automatic validation, retry logic, and support for multiple output modes (JSON, JSON Schema, tool calling, markdown), all while remaining framework-agnostic.
