PHP開発でBaidu Wenxin Yiyanのランダムステートメントの言語変換機能を実装するにはどうすればよいですか?

<?php
$url = 'https://api.drrrapi.com/baidu/wenxin/get_random_sentence'; // 文心一言接口URL
$response = file_get_contents($url);
$data = json_decode($response, true);
if ($data && isset($data['content'])) {
    $content = $data['content']; // 获得语句内容
    // 此处将语句存储到数据库或者直接输出显示即可
}

<?php

function translate($text, $from, $to, $appid, $appkey)
{
    $url = 'https://fanyi-api.baidu.com/api/trans/vip/translate';
    $salt = random_int(10000, 99999);
    $sign = md5($appid . $text . $salt . $appkey);
    $query = http_build_query([
        'q' => $text,
        'from' => $from,
        'to' => $to,
        'appid' => $appid,
        'salt' => $salt,
        'sign' => $sign,
    ]);
    $response = file_get_contents($url . '?' . $query);
    $result = json_decode($response, true);
    if ($result && isset($result['trans_result'][0]['dst'])) {
        return $result['trans_result'][0]['dst'];
    }
    return '';
}

// 使用百度翻译接口进行语言转换
$text = 'Hello, world!';
$from = 'en';
$to = 'zh';
$appid = 'your_appid';
$appkey = 'your_appkey';

$translatedText = translate($text, $from, $to, $appid, $appkey);
if ($translatedText) {
    // 转换成功，可以将转换后的语句存储到数据库或者直接输出显示
    echo $translatedText;
} else {
    // 转换失败，处理错误逻辑
    echo 'Translation failed.';
}
