How to Create an Online Consulting Bot with ChatGPT and PHP

Introduction:
With the rapid development of artificial intelligence, online consulting bots have become an essential part of many websites and applications. By integrating ChatGPT API with PHP, we can easily develop an intelligent online customer service bot. This article will guide you through the process of creating this bot and provide detailed code examples.

Step 1: Preparations

Before starting, make sure your server supports PHP and has the necessary PHP environment and dependencies installed.

Step 2: Obtain the ChatGPT API Key

First, visit the OpenAI website and register for an account. Once registered, you can apply for a ChatGPT API key. After obtaining the key, be sure to keep it safe.

Step 3: Install and Configure ChatGPT PHP

You can use Composer to install the required PHP libraries. Run the following command to install the ChatGPT-related dependencies:

composer require openai/plugin-gpt3

After installation, you need to configure the API key. Create a .env file in the root directory of your project and add the following content:

OPENAI_API_KEY=your_api_key_here

Replace "your_api_key_here" with the actual API key you obtained.

Step 4: Create a ChatGPT Client

In your PHP application, you can use the following code to create a ChatGPT client:

use OpenAIOpenAI;

$openai = new OpenAI([
    'api_key' => $_ENV['OPENAI_API_KEY'],
]);

$chatGpt = $openai->createChatCompletion();

Step 5: Engage in Conversation with the User

Using the code example below, you can engage in a multi-turn conversation with the user and get responses from the bot:

$messages = [
    ['role' => 'system', 'content' => 'You are a helpful assistant.'],
    ['role' => 'user', 'content' => 'Who won the world series in 2020?'],
    ['role' => 'assistant', 'content' => 'The Los Angeles Dodgers won the World Series in 2020.'],
    ['role' => 'user', 'content' => 'Where was it played?'],
    ['role' => 'assistant', 'content' => 'The games were played in Arlington, Texas, at the Globe Life Field.'],
];

$response = $chatGpt->create([
    'messages' => $messages,
]);

Step 6: Process the Bot’s Response

Here is an example of how to extract the bot’s response content:

$reply = end($response['choices'])['message']['content'];

Step 7: Output the Bot’s Response

Use the following code to output the bot's response to the user:

echo $reply;

Conclusion

With the steps outlined above, you can easily create an online consulting bot based on ChatGPT and PHP. From obtaining the API key to implementing user interaction, the process is straightforward and easy to follow. I hope this guide helps you get started and build a powerful bot for your website or application.

Good luck in your ChatGPT PHP development journey, and I hope you create an efficient and intelligent online consulting bot!
