How to use ChatGPT PHP to develop online consultation robots
Introduction:
With the rapid development of artificial intelligence, robot consultation is becoming more and more common. The development of an online consultation robot can be easily achieved through ChatGPT PHP. This article will lead readers to understand how to use ChatGPT PHP to develop an online consultation robot and provide specific code examples.
Step 1: Preparation
First, make sure that your server supports the PHP programming language and has installed the required related environments and dependent libraries.
Step 2: Obtain the ChatGPT API key
Visit the OpenAI official website (https://www.openai.com) to register and create an account. Then, apply for a ChatGPT API key. Once you obtain your API key, make sure you keep it in a safe place.
Step 3: Install and configure ChatGPT PHP
You can use Composer to install ChatGPT PHP. Execute the following code in the terminal:
composer require openai/plugin-gpt3
After the installation is complete, you need to configure it so that the API key can be used correctly. Create a .env file in the root directory of your project and add the following code to the file:
OPENAI_API_KEY=your_api_key_here
Replace "your_api_key_here" with your ChatGPT API key.
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: Have a conversation with the user
Using the following code example, you can have a conversation with the user and get the robot's reply:
$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, ]);
Multiple rounds of conversations between the user and the robot can be performed by adding the $messages
array dialogue. First, add the user with the role "system" in the $messages
array, followed by the interactive conversation between the user and the robot.
Step 6: Process the bot's reply
Use the following code to extract content from the bot's reply:
$reply = end($response['choices'])['message']['content'];
Step 7: Output the bot's reply
Finally, use the following Code to output the robot's reply to the user:
echo $reply;
Summary:
By following the above steps, we can easily develop an online consultation robot using ChatGPT PHP. From getting an API key to starting a conversation with the user to extracting the bot's responses, this article gives you a basic code sample.
I hope this article can be helpful to your ChatGPT PHP development journey. I wish you the best in developing a powerful online consultation robot!
