=================

Tip

For more detailed information and comprehensive guides, please visit our [official documentation](https://doctrine-pgvector.partitech.com)

Partitech Doctrine PgVector is a Doctrine extension for integrating PostgreSQL vector types into your PHP projects using Doctrine ORM. This module simplifies using vectors in your database by providing calculation functions such as distance, inner product, and cosine similarity.

📦 Installation
--------------

[](#-installation)

You can install Partitech Doctrine PgVector via Composer:

```
composer require partitech/doctrine-pgvector
```

⚙️ Configuration
----------------

[](#️-configuration)

Add the types and functions to your Doctrine configuration:

```
doctrine:
    dbal:
        types:
            vector: Partitech\DoctrinePgVector\Type\VectorType
    orm:
        dql:
            string_functions:
                distance: Partitech\DoctrinePgVector\Query\Distance
                inner_product: Partitech\DoctrinePgVector\Query\InnerProduct
                cosine_similarity: Partitech\DoctrinePgVector\Query\CosineSimilarity
```

🛠️ Usage
--------

[](#️-usage)

### Vector Types

[](#vector-types)

Use vector types directly in your Doctrine entities:

```
/** @Column(type="vector") */
private $vector;
```

### Available DQL Functions

[](#available-dql-functions)

- `distance(vector, vector)`
- `inner_product(vector, vector)`
- `cosine_similarity(vector, vector)`

These functions can be directly used in your Doctrine queries.

📌 Examples
----------

[](#-examples)

Example query using distance:

```
$query = $entityManager->createQuery(
    'SELECT e FROM Entity e ORDER BY distance(e.vector, :inputVector) ASC'
);
$query->setParameter('inputVector', [0.1, 0.2, 0.3]);
$result = $query->getResult();
```

✅ Testing and Development
-------------------------

[](#-testing-and-development)

To run unit tests:

```
composer test
```
