Preface – This post is part of the ChatGPT series.

To integrate ChatGPT in PHP, you can use the open-source GPT-3 PHP library provided by OpenAI. This library allows you to easily access the GPT-3 API from within your PHP code, allowing you to integrate GPT-3 functionality into your PHP applications.

Here is an example of how to use the GPT-3 PHP library to integrate GPT-3 into a PHP application:

// Import the GPT-3 PHP library
require_once __DIR__ . '/vendor/autoload.php';
use OpenAI\Client;
// Set up the GPT-3 API client
$openai = new Client(getenv('OPENAI_SECRET'));
// Use the GPT-3 API client to generate text
$response = $openai->completions()->create([
    'engine' => 'davinci',
    'prompt' => 'Hello, world!',
    'temperature' => 0.5,
    'max_tokens' => 1024,
    'top_p' => 1,
    'frequency_penalty' => 0,
    'presence_penalty' => 0
]);
// Print the generated text
echo $response->get('choices')[0]['text'];
