OpenAI PHP for Laravel 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:

• Nuno Maduro: github.com/sponsors/nunomaduro
• Sandro Gehri: github.com/sponsors/gehrisandro

Note: This repository contains the integration code of the OpenAI PHP for Laravel. If you want to use the OpenAI PHP client in a framework-agnostic way, take a look at the openai-php/client repository.

Get Started

Requires PHP 8.1+

First, install OpenAI via the Composer package manager:

composer require openai-php/laravel

Next, publish the configuration file:

php artisan vendor:publish --provider="OpenAI\Laravel\ServiceProvider"

This will create a config/openai.php configuration file in your project, which you can modify to your needs using environment variables:

OPENAI_API_KEY=sk-...

Finally, you may use the OpenAI facade to access the OpenAI API:

use OpenAI\Laravel\Facades\OpenAI;

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

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

Usage

For usage examples, take a look at the openai-php/client repository.

Testing

The OpenAI facade comes with a fake() method that allows you to fake the API responses.

The fake responses are returned in the order they are provided to the fake() method.

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.

use OpenAI\Laravel\Facades\OpenAI;
use OpenAI\Responses\Completions\CreateResponse;

OpenAI::fake([
    CreateResponse::fake([
        'choices' => [
            [
                'text' => 'awesome!',
            ],
        ],
    ]),
]);

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

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

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

// assert completion create request was sent
OpenAI::assertSent(Completions::class, function (string $method, array $parameters): bool {
    return $method === 'create' &&
        $parameters['model'] === 'text-davinci-003' &&
        $parameters['prompt'] === 'PHP is ';
});

For more testing examples, take a look at the openai-php/client repository.
