OpenAI PHP is a supercharged PHP API client that allows you to interact with the Open AI API.
Requires PHP 8.1+
First, install OpenAI via the Composer package manager:
composer require openai-php/clientThen, interact with OpenAI's API:
$client = OpenAI::client('YOUR_API_KEY');
$result = $client->completions()->create([
'model' => 'davinci',
'prompt' => 'PHP is',
]);
echo $result['choices'][0]['text']; // an open-source, widely-used, server-side scripting language.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'
