Setting up a chatbot website using GPT-3 and PHP can be done in a few simple steps. Here's how:

Install PHP on your computer: You can download and install PHP from the official website (https://www.php.net/downloads.php). Follow the instructions provided to complete the installation process.
Create a new folder for your chatbot website: Open your favorite text editor and create a new folder for your chatbot website. Save it as "index.php".
Add HTML code: Open the "index.php" file in your text editor and add the following HTML code:

<html>
<head>
<title>Chatbot Demo</title>
</head>
<body>
<h1>Chatbot Demo</h1>
<form method="post">
<label for="prompt">Enter your message:</label><br>
<input type="text" id="prompt" name="prompt"><br>
<label for="answer">Response:</label><br>
<input type="text" id="answer" name="answer" readonly><br>
<input type="submit" value="Send">
</form>
</body>
</html>

This code will create a simple webpage with a text box to enter a message and another text box to display the response.

Add PHP code: Below the HTML code, add the following PHP code:

<?php
require_once 'vendor/autoload.php';
use OpenAI\OpenAI;

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $prompt = $_POST['prompt'];
    $apiKey = 'YOUR_API_KEY_HERE';
    $engine = 'davinci';
    
    $openai = new OpenAI($apiKey);
    $response = $openai->complete($prompt, $engine);
    
    $answer = $response['choices'][0]['text'];
}
?>

This code will use the OpenAI API to generate a response based on the prompt entered by the user.

Install OpenAI for PHP: To use the OpenAI API in PHP, you need to install the OpenAI PHP SDK. You can do this using Composer by running the following command in your terminal:

composer require openai/php

This will install the OpenAI PHP SDK and all its dependencies.

Add your API key: Replace "YOUR_API_KEY_HERE" in the PHP code with your actual OpenAI API key.
Test your chatbot: Save the "index.php" file and open it in your web browser. Enter a message in the prompt text box and click "Send". The chatbot should generate a response based on the message.

That's it! You now have a simple chatbot website using GPT-3 and PHP.
