How to implement chat GPT in Laravel

1. Install the guzzlehttp/guzzle package using Composer:

   bash
   composer require guzzlehttp/guzzle
   

2. Create a new controller that will handle the chatbot logic:

   go
   php artisan make:controller ChatbotController
   

3. In the ChatbotController, import the GuzzleHttp\Client class:

   arduino
   use GuzzleHttp\Client;
   

4. Create a function that will handle the chatbot requests. In this function, you will make a POST request to the ChatGPT API endpoint and pass the user's message as a parameter:

   php
   public function chatbot(Request $request)
   {
       $client = new Client();
       $response = $client->post('https://api.openai.com/v1/engine/<ENGINE-ID>/completions', [
           'headers' => [
               'Authorization' => 'Bearer <API-KEY>',
               'Content-Type' => 'application/json',
           ],
           'json' => [
               'prompt' => $request->message,
               'max_tokens' => 50,
               'temperature' => 0.7,
           ],
       ]);
       $result = json_decode($response->getBody()->getContents(), true);
       return response()->json(['message' => $result['choices'][0]['text']]);
   }

5. In the routes/web.php file, create a new route that will point to the chatbot function in the ChatbotController:

   css
   Route::post('/chatbot', 'ChatbotController@chatbot');
   

6. Finally, in your front-end, create a form that will submit the user's message to the chatbot route using AJAX:

   php
   <form id="chat-form">
       <input type="text" name="message" placeholder="Type your message...">
       <button type="submit">Send</button>
   </form>
   <div id="chat-messages"></div>
   <script>
       $('#chat-form').submit(function(e) {
           e.preventDefault();
           $.ajax({
               type: 'POST',
               url: '/chatbot',
               data: $('#chat-form').serialize(),
               success: function(response) {
                   $('#chat-messages').append('<p>You: ' + $('#chat-form input[name=message]').val() + '</p>');
                   $('#chat-messages').append('<p>Chatbot: ' + response.message + '</p>');
                   $('#chat-form input[name=message]').val('');
               },
           });
       });
   </script>

That's it! With these steps, you should now be able to implement ChatGPT in Laravel
