三, ChatGPT PHP application examples in website development
In order to better understand the application of ChatGPT PHP in website development, we will start with a simple online Q&A system and demonstrate how to use ChatGPT PHP to handle user questions and Generate reply. The following is a basic PHP filechatbot.php, used to handle user input and output:

complete($userMessage); // 获取回复内容 $botReply = $response['choices'][0]['message']['content']; // 返回回复给用户 echo json_encode(['reply' => $botReply]);

In the above code, we first introduce the ChatGPT library and create a ChatCompletion Example. Then, we call thecomplete()method based on the user's input to get the reply. Finally, we return a reply to the user.

On the web page, we can use the following HTML code to display the dialog box and send user input:

 
 
  发送 
 
 

In the above example, we use JavaScript code to monitor the click event of the send button and obtain user input. , and send a POST request to the server via XHR (XMLHttpRequest). After the server responds, we use JavaScript to display the returned reply on the web page and clear the user input box.
