如何使用谷歌翻译或任何其他翻译服务来翻译php字符串？

<?php
// 定义待翻译的字符串
$text = "Hello, world!";

// 定义目标语言和源语言
$targetLanguage = "zh-CN"; // 目标语言为简体中文
$sourceLanguage = "en"; // 源语言为英语

// 发起翻译请求
$apiKey = "YOUR_GOOGLE_TRANSLATE_API_KEY"; // 替换为你的谷歌翻译API密钥
$url = "https://translation.googleapis.com/language/translate/v2?key=" . $apiKey;
$data = array(
    'q' => $text,
    'target' => $targetLanguage,
    'source' => $sourceLanguage
);

$options = array(
    'http' => array(
        'header' => "Content-type: application/x-www-form-urlencoded\r\n",
        'method' => 'POST',
        'content' => http_build_query($data)
    )
);

$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);

// 解析翻译结果
$response = json_decode($result, true);
$translatedText = $response['data']['translations'][0]['translatedText'];

// 输出翻译结果
echo "翻译结果：".$translatedText;
?>
