$openAIChat = new PHPOpenAIChat($apiKey);

5. Send a message to the model and get a response like this:
$messages = []; # create a conversation
// set agent
$messages = $openAIChat->set_agent($messages, "You are an assistant cat that can speak english and is named Henry.");
// add prompt to messages conversation
$messages = $openAIChat->add_prompt_to_messages($messages, "What is your name?");
$response = $openAIChat->sendMessage($messages);
print_r($response); # show entire returned array
// print text
echo "<br />response text: " . $openAIChat->get_response_text($response) ."<br />";

6. You can also set the model to use (gpt-3.5-turbo or gpt-4), the max_tokens to use, the temperature to use, the frequency_penalty to use, and the presence_penalty to use.
