php翻译功能实现
PHP 翻译功能实现方法
使用 Google Translate API
注册 Google Cloud 账号并启用 Cloud Translation API，获取 API 密钥。安装官方客户端库：
composer require google/cloud-translate示例代码：
require 'vendor/autoload.php';
use Google\Cloud\Translate\V2\TranslateClient;
$translate = new TranslateClient(['key' => 'YOUR_API_KEY']);
$result = $translate->translate('Hello world', ['target' => 'zh-CN']);
echo $result['text'];使用 Microsoft Azure Translator
创建 Azure 资源获取密钥和终结点。安装 Azure SDK：
composer require microsoft/azure-storage示例代码：
require 'vendor/autoload.php';
use MicrosoftAzure\Storage\Common\ServicesBuilder;
$connectionString = "Endpoint=YOUR_ENDPOINT;Key=YOUR_KEY";
$translator = ServicesBuilder::getInstance()->createTranslationService($connectionString);
$result = $translator->translate('Hello', 'fr');
echo $result[0]['Translations'][0]['Text'];使用 DeepL API
获取 DeepL API 密钥，通过 cURL 发送请求：
$text = "Hello world";
$targetLang = "DE";
$apiKey = "YOUR_DEEPL_KEY";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.deepl.com/v2/translate");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query([
'text' => $text,
'target_lang' => $targetLang,
'auth_key' => $apiKey
]));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
$result = json_decode($response, true);
echo $result['translations'][0]['text'];使用本地翻译库
安装 PHP 本地化包：
composer require php-intl示例代码：
$translator = new MessageFormatter('fr_FR', "{0,number}");
echo $translator->format([42]); // 输出法语格式数字注意事项
API 服务通常有免费额度限制，超出后会产生费用。建议缓存翻译结果减少 API 调用。处理特殊字符时注意转义，非拉丁语系文本需确保编码正确。
