class Example extends BaseFunction
{
    public function __construct(
        private $location = 'Londra',
        private $unit = 'farhenheit',
    ) {
    }

    public function properties(): array
    {
        return $this->parameters();
    }
    public static function required(): array
    {
        return ['location'];

    }

    public function handle(): string
    {
        return $this->json([
            "location" => $this->location,
            "temperature" => "72",
            "unit" => $this->unit,

$yourApiKey = 'XXXXXXXXXXXX';
$yourOrganization = 'XXXXXXXXXX';
$example = new Example();

$messages = [
    ["role" => "system", "content" => "Hello I am helper"],
];
$functions = [
    $example->function()
];
$client = new Client($yourApiKey, $yourOrganization);
$openAI = new OpenAI($example, $client);
$chat = $openAI->chat($functions, $messages, 'handle'); //handle is functionName on example
var_dump($chat->say('How is weather in London?'));

First step, You call Client class

<?php
    use Ftuzlu\OpenAI\Client;

    $yourAPIKey=XXXXXX;
    $yourOrganization=XXXXX;
    $baseUrl = 'https://api.openai.com/';
    $client = new Client($yourApiKey, $yourOrganization, $baseUrl);

Second Step

<?php
    use Ftuzlu\OpenAI\OpenAI;

   $example = new Example(); //Example is your Class
   $openAI = new OpenAI($example, $client);
   $chat = $openAI->chat($functions, $messages, 'handle'); //handle is also your class's functionName.
