GitHub - wpeverest/openai-php-client: ⚡️ OpenAI PHP is a supercharged community-maintained PHP API client that allows you to interact with OpenAI API.

OpenAI PHP is a community-maintained PHP API client that allows you to interact with the Open AI API. If you or your business relies on this package, it's important to support the developers who have contributed their time and effort to create and maintain this valuable tool:

Get Started

Requires PHP 8.1+

First, install OpenAI via the Composer package manager:

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.

composer require guzzlehttp/guzzle

Then, interact with OpenAI's API:

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

$result = $client->completions()->create([
    'model' => 'text-davinci-003',
    'prompt' => 'PHP is',
]);

echo $result['choices'][0]['text']; // an open-source, widely-used, server-side scripting language.

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

$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(new \GuzzleHttp\Client([])) // default: HTTP client found using PSR-18 HTTP Client Discovery
    ->withHttpHeader('X-My-Header', 'foo')
    ->withQueryParam('my-param', 'bar')
    ->make();
