This repository provides a PHP library for integrating with the pgvector extension in PostgreSQL, offering support for vector, halfvec, bit, and sparsevec data types. It includes core vector classes (Vector, HalfVector, SparseVector) and integrations for Laravel (Eloquent models, migrations, and a service provider) and Doctrine (DBAL types and DQL functions). The library enables developers to store and query vector embeddings using various distance metrics (L2, inner product, cosine, etc.) in their PHP applications. The architecture is modular, with separate namespaces for core functionality, Laravel, and Doctrine integrations, allowing users to adopt only the parts they need.
