Write a markdown tutorial with code examples to get started with OpenAI’s GPT-3 completion API, using the latest text-davinci-003 model, in a modern symfony 6 web application using PHP 8 features. The main example is about having GPT-3 fill a symfony form (with multiple fields) initial data using a textarea where the user can enter a natural language description of the information. The code dynamically builds a completion prompt by using the symfony form field names and description. The code uses a composer package for the openapi sdk that is uses guzzle. The code examples only include changes to the code and not entire files.
Before the tutorial write a viral tweet to share the tutorial.

Tutorial: Using OpenAI's GPT-3 Completion API in a Symfony 6 Web Application
This tutorial will show you how to use the latest text-davinci-003 model of OpenAI's GPT-3 Completion API to dynamically fill a Symfony 6 web application form with natural language data using PHP 8 features.
Step 1: Install OpenAI SDK
Install the OpenAI SDK using Composer by running the following command.
composer require openai/sdk
Step 2: Create a GPT-3 Client
Create a GPT-3 client object using the OpenAI SDK with Guzzle.
$client = newOpenAI\Client('<YOUR_API_KEY>', new \GuzzleHttp\Client());
Step 3: Build the Completion Prompt
Build the completion prompt using the Symfony form field names and descriptions.
$prompt =
'Please enter a natural language description of the form fields: '.
implode(', ', array_map(
function ($field) {
return$field['name'].' ('.$field['description'].')';
},
$form->getFields()
));
Step 4: Make the GPT-3 Completion Request
Make a GPT-3 completion request with the prompt and the natural language data.
