## Get Started

> **Requires [PHP 8.1+](https://php.net/releases/)**

First, install OpenAI via the [Composer](https://getcomposer.org/) package manager:

```bash
composer require openai-php/client
```

Ensure that the `php-http/discovery` composer plugin is allowed to run or install a client manually if your project does not already have a PSR-18 client integrated.
```bash
composer require guzzlehttp/guzzle
```

Then, interact with OpenAI's API:

```php
$yourApiKey = getenv('YOUR_API_KEY');
$client = OpenAI::client($yourApiKey);

$result = $client->chat()->create([
    'model' => 'gpt-4',
    'messages' => [
        ['role' => 'user', 'content' => 'Hello!'],
    ],
]);

echo $result->choices[0]->message->content; // Hello! How can I assist you today?
```

If necessary, it is possible to configure and create a separate client.

```php
$yourApiKey = getenv('YOUR_API_KEY');

$client = OpenAI::factory()
    ->withApiKey($yourApiKey)
    ->withOrganization('your-organization') // default: null
    ->withBaseUri('openai.example.com/v1') // default: api.openai.com/v1
    ->withHttpClient($client = new \GuzzleHttp\Client([])) // default: HTTP client found using PSR-18 HTTP Client Discovery
    ->withHttpHeader('X-My-Header', 'foo')
    ->withQueryParam('my-param', 'bar')
    ->withStreamHandler(fn (RequestInterface $request): ResponseInterface => $client->send($request, [
        'stream' => true // Allows to provide a custom stream handler for the http client.
    ]))
    ->make();
```

## Usage

$response->fileCounts->failed; // 0
$response->fileCounts->cancelled; // 0
$response->fileCounts->total; // 1

$response->toArray(); // ['id' => 'vsfb_123', ...]
```

#### `cancel`

Cancel a vector store file batch. This attempts to cancel the processing of files in this batch as soon as possible.

```php
$response = $client->vectorStores()->batches()->cancel(
    vectorStoreId: 'vs_vzfQhlTWVUl38QGqQAoQjeDF',
    fileBatchId: 'vsfb_123',
);

$response->id; // 'vsfb_123'
$response->object; // 'vector_store.files_batch'
$response->createdAt; // 1698107661
$response->vectorStoreId; // 'vs_vzfQhlTWVUl38QGqQAoQjeDF'
$response->status; // 'cancelling'
$response->fileCounts->inProgress; // 1
$response->fileCounts->completed; // 0
$response->fileCounts->failed; // 0
$response->fileCounts->cancelled; // 0
$response->fileCounts->total; // 1

$response->toArray(); // ['id' => 'vsfb_123', ...]
```

#### `list`

Returns a list of vector store files.

```php
$response = $client->vectorStores()->batches()->listFiles(
    vectorStoreId: 'vs_vzfQhlTWVUl38QGqQAoQjeDF',
    fileBatchId: 'vsfb_123',
    parameters: [
        'limit' => 10,
    ],
);

$response->object; // 'list'
$response->firstId; // 'file-fUU0hFRuQ1GzhOweTNeJlCXG'
$response->lastId; // 'file-D5DPOgBxSoEBTmYBgUESdPpa'
$response->hasMore; // true

foreach ($response->data as $result) {
    $result->id; // 'file-fUU0hFRuQ1GzhOweTNeJlCXG'
    // ...
}

$response->toArray(); // ['object' => 'list', ...]]
```

### `Edits` Resource (deprecated)

> OpenAI has deprecated the Edits API and will stop working by January 4, 2024.
> https://openai.com/blog/gpt-4-api-general-availability#deprecation-of-the-edits-api

#### `create`

Creates a new edit for the provided input, instruction, and parameters.

```php
$response = $client->edits()->create([
    'model' => 'text-davinci-edit-001',
    'input' => 'What day of the wek is it?',
    'instruction' => 'Fix the spelling mistakes',
]);

$response->object; // 'edit'
$response->created; // 1589478378

foreach ($response->choices as $result) {
    $result->text; // 'What day of the week is it?'
    $result->index; // 0
}

$response->usage->promptTokens; // 25,
$response->usage->completionTokens; // 32,
$response->usage->totalTokens; // 57

$response->toArray(); // ['object' => 'edit', ...]
```

## Meta Information

On all response objects you can access the meta information returned by the API via the `meta()` method.

```php
$response = $client->completions()->create([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'Say this is a test',
]);

$meta = $response->meta();

$meta->requestId; // '574a03e2faaf4e9fd703958e4ddc66f5'

$meta->openai->model; // 'gpt-3.5-turbo-instruct'
$meta->openai->organization; // 'org-jwe45798ASN82s'
$meta->openai->version; // '2020-10-01'
$meta->openai->processingMs; // 425

$meta->requestLimit->limit; // 3000
$meta->requestLimit->remaining; // 2999
$meta->requestLimit->reset; // '20ms'

$meta->tokenLimit->limit; // 250000
$meta->tokenLimit->remaining; // 249984
$meta->tokenLimit->reset; // '3ms'
```

The `toArray()` method returns the meta information in the form originally returned by the API.

```php
$meta->toArray();

// [ 
//   'x-request-id' => '574a03e2faaf4e9fd703958e4ddc66f5',
//   'openai-model' => 'gpt-3.5-turbo-instruct',
//   'openai-organization' => 'org-jwe45798ASN82s',
//   'openai-processing-ms' => 402,
//   'openai-version' => '2020-10-01',
//   'x-ratelimit-limit-requests' => 3000,
//   'x-ratelimit-remaining-requests' => 2999,
//   'x-ratelimit-reset-requests' => '20ms',
//   'x-ratelimit-limit-tokens' => 250000,
//   'x-ratelimit-remaining-tokens' => 249983,
//   'x-ratelimit-reset-tokens' => '3ms',
// ]
```

On streaming responses you can access the meta information on the reponse stream object.

```php
$stream = $client->completions()->createStreamed([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'Say this is a test',
]);
    
$stream->meta(); 
```

## Troubleshooting

### Timeout

You may run into a timeout when sending requests to the API. The default timeout depends on the HTTP client used.

You can increase the timeout by configuring the HTTP client and passing in to the factory.

This example illustrates how to increase the timeout using Guzzle.
```php
OpenAI::factory()
    ->withApiKey($apiKey)
    ->withOrganization($organization)
    ->withHttpClient(new \GuzzleHttp\Client(['timeout' => $timeout]))
    ->make();
```

## Testing

The package provides a fake implementation of the `OpenAI\Client` class that allows you to fake the API responses.

To test your code ensure you swap the `OpenAI\Client` class with the `OpenAI\Testing\ClientFake` class in your test case.

The fake responses are returned in the order they are provided while creating the fake client.

All responses are having a `fake()` method that allows you to easily create a response object by only providing the parameters relevant for your test case.

```php
use OpenAI\Testing\ClientFake;
use OpenAI\Responses\Completions\CreateResponse;

$client = new ClientFake([
    CreateResponse::fake([
        'choices' => [
            [
                'text' => 'awesome!',
            ],
        ],
    ]),
]);

$completion = $client->completions()->create([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'PHP is ',
]);

expect($completion['choices'][0]['text'])->toBe('awesome!');
```

In case of a streamed response you can optionally provide a resource holding the fake response data.

```php
use OpenAI\Testing\ClientFake;
use OpenAI\Responses\Chat\CreateStreamedResponse;

$client = new ClientFake([
    CreateStreamedResponse::fake(fopen('file.txt', 'r'););
]);

$completion = $client->chat()->createStreamed([
        'model' => 'gpt-3.5-turbo',
        'messages' => [
            ['role' => 'user', 'content' => 'Hello!'],
        ],
]);

expect($response->getIterator()->current())
        ->id->toBe('chatcmpl-6yo21W6LVo8Tw2yBf7aGf2g17IeIl');
```

After the requests have been sent there are various methods to ensure that the expected requests were sent:

```php
// assert completion create request was sent
$client->assertSent(Completions::class, function (string $method, array $parameters): bool {
    return $method === 'create' &&
        $parameters['model'] === 'gpt-3.5-turbo-instruct' &&
        $parameters['prompt'] === 'PHP is ';
});
// or
$client->completions()->assertSent(function (string $method, array $parameters): bool {
    // ...
});

// assert 2 completion create requests were sent
$client->assertSent(Completions::class, 2);

// assert no completion create requests were sent
$client->assertNotSent(Completions::class);
// or
$client->completions()->assertNotSent();

// assert no requests were sent
$client->assertNothingSent();
```

To write tests expecting the API request to fail you can provide a `Throwable` object as the response.

```php
$client = new ClientFake([
    new \OpenAI\Exceptions\ErrorException([
        'message' => 'The model `gpt-1` does not exist',
        'type' => 'invalid_request_error',
        'code' => null,
    ])
]);

// the `ErrorException` will be thrown
$completion = $client->completions()->create([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'PHP is ',
]);
```

## Services

### Azure

In order to use the Azure OpenAI Service, it is necessary to construct the client manually using the factory.

```php
$client = OpenAI::factory()
    ->withBaseUri('{your-resource-name}.openai.azure.com/openai/deployments/{deployment-id}')
    ->withHttpHeader('api-key', '{your-api-key}')
    ->withQueryParam('api-version', '{version}')
    ->make();
```

To use Azure, you must deploy a model, identified by the {deployment-id}, which is already incorporated into the API calls. As a result, you do not have to provide the model during the calls since it is included in the `BaseUri`.

Therefore, a basic sample completion call would be:

```php
$result = $client->completions()->create([
    'prompt' => 'PHP is'
]);
```
