sure! Use the PHP language to call the OpenAI API to interact with the ChatGPT-3.5 model. First, make sure you have PHP 7.2 or newer installed and have an OpenAI API key available.
Below is a basic PHP example showing how to use the OpenAI API to talk to the ChatGPT-3.5 model:
```php
<?php
// 函数用于向OpenAI API发送请求
function openaiChat($messages) {
$apiKey = 'YOUR_OPENAI_API_KEY';
$url = 'https://api.openai.com/v1/engines/davinci-codex/completions';
$headers = array(
'Content-Type: application/json',
'Authorization: Bearer ' . $apiKey
);
$data = array(
'messages' => $messages
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
// 设置用户和AI的初始对话
$chat = array(
array('role' => 'system', 'content' => 'You are a helpful assistant.'),
array('role' => 'user', 'content' => 'Who won the world series in 2020?'),
array('role' => 'assistant', 'content' => '')
);
// 与AI进行对话
while (true) {
// 调用OpenAI API发送请求
$response = openaiChat($chat);
// 处理API响应
$json = json_decode($response, true);
$message = end($json['choices']);
$chat[] = array('role' => 'user', 'content' => ''); // 准备用户输入的占位符
if ($message['role'] == 'assistant') {
// 显示AI的回复
echo 'AI: ' . $message['message']['content'] . "\n";
// 获取用户输入
$userInput = trim(fgets(STDIN));
// 更新对话
$chat[count($chat) - 1]['content'] = $userInput;
} else {
// AI已经完成对话,退出循环
break;
}
}
```
The above is a basic example, you can modify and extend it according to your needs. Remember to replace `YOUR_OPENAI_API_KEY` with your own OpenAI API key.
This code will implement a simple dialogue loop until the AI finishes the dialogue. In each loop, it sends a request to the OpenAI API, gets a reply from the AI, and then waits for the user to enter the next line of dialogue. The AI's reply is extracted by `$message['message']['content']`.
Note that user input in this example is obtained on the command line using `fgets(STDIN)`. If you use your code in other contexts such as a web application, you may need to use a different method for getting user input.
Hope this example can help you! Feel free to ask if further guidance is needed.
