What is this?

Curated list of PHP libraries and tools for Machine Learning, AI, NLP, LLMs and Data Science.
Focused on code-first resources: packages, SDKs, frameworks, and building blocks.
Aimed at PHP developers who want to add intelligent features to existing apps or build new AI-powered systems.

How to use this list

Classic ML / traditional models – start with php-ai/php-ml and RubixML/RubixML.
LLM-powered apps & agents – see LLMs & AI APIs, Embeddings & Vector Search, and framework integrations (Laravel/Symfony).
RAG (Retrieval-Augmented Generation) – combine php-rag with vector databases like pgvector or Meilisearch.
Numerical computing & math – explore Math, Statistics & Linear Algebra for tensors, matrices, and statistics.
Production integration – use Interop & Model Serving and framework integrations to wire models into real apps.

Quick Start

For beginners new to PHP ML/AI:

# Install a core ML library
composer require rubix/ml
composer require php-ai/phpml

# Install LLM client
composer require openai-php/client

# Install vector search for RAG
composer require llphant/llphant

Basic examples:

Classification: Use RubixML/RubixML with KNearestNeighbors for simple classification tasks
LLM integration: Use openai-php/client to call GPT models from PHP
Text analysis: Use php-ai/php-ml for sentiment analysis and tokenization
Vector search: Use LLPhant/LLPhant with pgvector for semantic search
