    'Authorization',
    'Bearer YOUR_API_KEY'
);

// 创建 OpenAI API 客户端
$client = new DefaultApi(null, $configuration);

// 设置对话的系统提示消息
$system_prompt = "您是有关 PHP 开发的专家。请与我的 PHP 聊天机器人开始对话：";

// 设置用户提示消息
$user_prompt = "任意用户输入的消息";

// 设置对话的历史记录
$chat_history = array(
    array('role' => 'system', 'content' => $system_prompt),
