ChatGPT PHP technical analysis: Building a real-time recommendation function for intelligent chatbots requires specific code examples

Abstract: With the rapid development of artificial intelligence, chatbots have become A common tool in modern society. This article will introduce how to use ChatGPT and PHP programming language to build an intelligent chatbot and implement real-time recommendation function. We will explain the working principle of ChatGPT in detail and give specific code examples to help readers get started quickly.

1. Introduction
   With the popularity of the Internet, people's needs are becoming more and more diverse. However, traditional intelligent chatbots often cannot meet the personalized needs of users. In order to solve this problem, we can use artificial intelligence technology to build an intelligent chatbot and add real-time recommendation functions to better provide users with personalized services. ChatGPT is a powerful natural language processing model that can help us achieve this goal.
2. How ChatGPT works
   ChatGPT is a natural language processing model based on deep learning. It learns people's question-asking and answering patterns in conversations by training on a large conversation corpus. When building a chatbot using ChatGPT, we first need to prepare a large amount of conversation data. Then, these data are input into the ChatGPT model for training, so that the model can learn to give reasonable answers to various questions. Finally, we can integrate the trained ChatGPT model into our chatbot.
3. Building the real-time recommendation function of chatbots
   When building chatbots, we usually need to consider the personalized needs of users. In order to better meet these needs, we can add a real-time recommendation function to recommend relevant information to users based on their questions.

In the PHP programming language, we can implement the real-time recommendation function by calling the ChatGPT API. First, we need to use PHP’s curl function to send an HTTP request to the ChatGPT API. The request needs to contain the user's question and set appropriate parameters. We can then parse the API's response to get the answer generated by the ChatGPT model.

The following is a specific code example:

<?php
function getRecommendation($question) {
    $api_url = 'https://api.openai.com/v1/engines/davinci-codex/completions';
    $headers = array(
        'Content-Type: application/json',
        'Authorization: Bearer YOUR_API_KEY'
    );
    $data = array(
        'prompt' => $question,
        'max_tokens' => 100,
        'temperature' => 0.7
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $api_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

    $response = curl_exec($ch);
    curl_close($ch);

    $answer = json_decode($response, true)['choices'][0]['text'];

    return $answer;
}

// 示例用法
$question = '请问有什么好的餐厅推荐？';
$recommendation = getRecommendation($question);

echo '根据您的提问，我为您推荐以下餐厅：' . $recommendation;
?>

In the above example code, the getRecommendation function accepts a question as a parameter and returns a recommended answer. We construct an HTTP request inside the function and call the ChatGPT API to obtain the recommended results. Finally, we print out the recommended results.

It is worth noting that YOUR_API_KEY in the sample code needs to be replaced with your ChatGPT API key. You can register and obtain this key on OpenAI’s official website.

4. Summary
   This article introduces how to use ChatGPT and PHP programming language to build an intelligent chat robot and implement real-time recommendation function. We explain how ChatGPT works in detail and provide specific code examples. Readers can perform practical operations based on the sample code, quickly build their own chatbot, and add personalized real-time recommendation functions according to needs.
