ChatGPT PHP technology analysis: key steps to build an automated intelligent interactive system, specific code examples are required

1. Introduction

ChatGPT It is a language model based on artificial intelligence that can generate realistic dialogue and realize automated intelligent interaction. It is widely used in customer service robots, voice assistants and other fields in various scenarios. This article will introduce how to use PHP language to build an automated intelligent interaction system based on ChatGPT, and provide specific code examples.

2. Preparation

First, we need to register an OpenAI account and obtain the API key. The API key is the necessary credential to communicate with ChatGPT. After obtaining the API key, we can use Composer to install the OpenAI API’s PHP SDK library.

composer require openai/api

Next, create a PHP file and introduce the OpenAI API library.

<?php

require 'vendor/autoload.php';

use OpenAIApiLanguageCompletionv1LanguageCompletion;
use OpenAIApiLanguageClassification;

// 设置API密钥
$apiKey = "YOUR_API_KEY";

3. Implementing the automated intelligent interaction system

Next, we need to implement the key steps of the automated intelligent interaction system. The first step is to enter the user's question and submit it to ChatGPT.

// 用户输入的问题
$userInput = "请问，今天的天气如何？";

// ChatGPT的回答
$chatGptResponse = LanguageCompletion::create([
    'prompt' => $userInput,
    'model' => 'gpt-3.5-turbo',
    'max_tokens' => 100,
    'temperature' => 0.7,
    'n' => 1
]);

In the above code, we send a text prompt (prompt) to ChatGPT through the API and specify the language model (model) used. We can also control the length of the answer, the diversity of the answer, etc. by adjusting parameters. Next, we extract the ChatGPT answer text from the answer.

// 提取回答文本
$chatGptAnswer = $chatGptResponse->choices[0]->text;

Next, we can perform corresponding follow-up operations based on the answers given by ChatGPT. For example, we can send the answer to the user or perform further processing based on the answer.

// 处理ChatGPT的回答
echo "ChatGPT回答：" . $chatGptAnswer;

// 其他后续操作
// ...

Finally, we need to make sure we end the conversation appropriately to avoid unnecessary waste of resources.

// 结束对话
unset($chatGptResponse);

4. Summary

Through the above steps, we can use the PHP language to build an automated intelligent interaction system based on ChatGPT. We first register an OpenAI account and obtain an API key. Then, install the PHP SDK library of OpenAI API through Composer and import the library file. Next, we enter the user's question and submit it to ChatGPT. Finally, we extract the ChatGPT answer text from the answer and perform follow-up operations as needed. It is important to note that we need to end the conversation appropriately to avoid wasting resources.

I hope this article will be helpful to developers who use PHP to build automated intelligent interactive systems. Detailed code examples and more application scenarios can be found in OpenAI’s official documentation.
