Short Summary

This guide explains how to integrate OpenAI's GPT-3 API into a PHP web application for text generation. It outlines the required setup, including obtaining an API key and configuring a project structure. The implementation includes:

• config.php for securely storing the API key.
• gpt3.php for managing API requests and responses via cURL.
• index.php for a user-friendly web interface to collect prompts and display responses.

The guide provides step-by-step code examples, emphasizes security and best practices, and suggests enhancements for a more robust application.

Prerequisites

1. API Key: Obtain an OpenAI API key from OpenAI.
2. Environment Setup: Ensure PHP 5.6 is installed with cURL enabled.

---

Step 1: Set Up the Project

Create a basic folder structure:

project/
├── index.php
├── gpt3.php
└── config.php

---

Step 2: Configuration (config.php)

This file will store the OpenAI API key.

<?php
// config.php
define('OPENAI_API_KEY', 'your-openai-api-key-here');

---

Step 3: Create the GPT-3 Integration Logic (gpt3.php)

This file handles communication with the OpenAI API.

<?php
// gpt3.php
require_once 'config.php';

function generateText($prompt) {
    $apiUrl = 'https://api.openai.com/v1/completions';
    $data = [
        'model' => 'text-davinci-003', // Adjust model as needed
        'prompt' => $prompt,
        'max_tokens' => 100, // Set response length
        'temperature' => 0.7, // Creativity level
    ];
}

---

Step 4: Build the Web Interface (index.php)

Create a simple HTML form for input and output.

    <h1>GPT-3 Text Generator</h1>
    <form method="POST">
        <textarea name="prompt" placeholder="Enter your prompt here..."></textarea>
        <button type="submit">Generate Text</button>
    </form>
    <?php if ($response): ?>
        <div>




<hr>

<h3>
  
  
  Step 5: Test the Application
</h3>

<ol>
<li>Run a local server using PHP:
</li>
</ol>

<pre class="brush:php;toolbar:false">   php -S localhost:8000

1. Open http://localhost:8000 in your browser.
2. Enter a prompt, such as:

   Write a short story about a curious cat.

1. Submit the form to see the generated text.

Conclusion

Integrating OpenAI’s GPT-3 API into a PHP application is achievable with some adjustments for the older PHP version. By leveraging cURL, the application effectively communicates with the OpenAI API to generate text responses based on user prompts. This guide provides a foundational implementation, allowing developers to extend and customize the project to suit specific requirements.

Key takeaways:

• Use secure configurations for API keys.
• Ensure error handling for a smooth user experience.
• Explore various API parameters (e.g., max_tokens, temperature) to adjust output characteristics.

This integration opens the door for dynamic text generation features, making it a valuable addition to web applications. For more advanced functionalities, consider upgrading your environment and exploring modern PHP versions.
