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

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.

Usage

Models Resource

list

Lists the currently available models, and provides basic information about each one such as the owner and availability.

$response = $client->models()->list();

$response->object; // 'list'

foreach ($response->data as $result) {
    $result->id; // 'text-davinci-003'
    $result->object; // 'model'
    // ...
}

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

retrieve

Retrieves a model instance, providing basic information about the model such as the owner and permissioning.

$response = $client->models()->retrieve('text-davinci-003');

$response->id; // 'text-davinci-003'
$response->object; // 'model'
$response->created; // 1642018370
$response->ownedBy; // 'openai'
$response->root; // 'text-davinci-003'
$response->parent; // null

foreach ($response->permission as $result) {
    $result->id; // 'modelperm-7E53j9OtnMZggjqlwMxW4QG7' 
    $result->object; // 'model_permission' 
    $result->created; // 1664307523
