ChatGPT PHP development practice: creating intelligent navigation assistant function

Introduction:
ChatGPT is an open source artificial intelligence language model developed by OpenAI. It can be used to create chatbots, smart assistants, or other natural language processing applications. This article will introduce how to use PHP language to develop an intelligent navigation assistant function, providing a user-friendly question and answer system through ChatGPT to help users find the information they need.

Step 1: Environment setup
First, make sure PHP and Composer are installed on the server. Then, create a new PHP file in the project directory, such as index.php. Next, we will use Composer to install the ChatGPT PHP package officially provided by OpenAI.

In the command line, enter the project directory and run the following command:

composer require openai/php-chatgpt

Step 2: Introduce the ChatGPT class and generate API credentials
In the index.php file, we first need to introduce ChatGPT class and generate an OpenAI API credential. Replace YOUR_API_KEY with your OpenAI API credentials:

<?php
require 'vendor/autoload.php';

use OpenaiApiChatCompleteRequest;
use OpenaiConfig;

$apiKey = 'YOUR_API_KEY';
$config = new Config($apiKey);

Step 3: Implement the Q&A feature of ChatGPT
In the PHP file, we can have a conversation by sending a request to the OpenAI API.

In the index.php file, we can create a simple HTML form to receive user input:

<form method="POST">
  <input type="text" name="user_input" placeholder="请输入您的问题">
  <input type="submit" value="提交">
</form>

Then, we can Obtain user input from the index.php file and use ChatGPT to generate a response:

if(isset($_POST['user_input'])){
  // 获取用户输入
  $userInput = $_POST['user_input'];

  // 创建 ChatCompleteRequest 对象
  $request = new ChatCompleteRequest();
  $request->setModel('gpt-3.5-turbo');
  $request->setMessages([['role' => 'system', 'content' => '您好，请问有什么可以帮助您的呢？'], ['role' => 'user', 'content' => $userInput]]);

  // 调用 ChatComplete API
  $response = $config->openai()->chat()->create($request);

  // 打印 ChatGPT 响应
  echo $response->getChoices()[0]->get('message')->get('content');
}

Step 4: Improve the navigation assistant function
We can provide users with templates for frequently asked questions to make it more convenient for users to ask questions. For example, we can pre-define some common questions and corresponding answers:

$commonQuestions = [
  '如何重置密码' => '您可以在用户设置中找到密码重置选项。',
  '如何修改个人资料' => '请登录后访问个人资料页面，您可以在那里修改您的个人资料。',
  '如何联系客服' => '您可以通过客服热线 123-456-789，或发送电子邮件至 support@example.com 与我们取得联系。'
];

Then, after receiving user input, we can check whether the user input matches the predefined frequently asked questions and return the corresponding answers:

if(isset($_POST['user_input'])){
  // ... 之前的代码

  // 检查用户输入是否为常见问题
  foreach($commonQuestions as $question => $answer){
    if(strtolower($userInput) == strtolower($question)){
      echo $answer;
      exit();
    }
  }
}

Conclusion:
By using PHP and ChatGPT, we can easily create an intelligent navigation assistant function to provide users with question and answer services. Developers can further improve functions and provide more frequently asked questions and corresponding answers based on actual needs. I hope this article can provide you with some reference and help in developing intelligent navigation assistant functions.
