PHP Baidu Translation API realizes mutual translation method sharing from German to English

PHP Baidu Translation API realizes the sharing of mutual translation methods from German to English

Introduction:
With the development of globalization, language translation has become a necessary factor for cross-border communication and cooperation. Baidu Translation API provides developers with translation services between 27 languages ​​around the world. This article will introduce how to use PHP language combined with Baidu Translation API to realize the mutual translation function from German to English, and share the corresponding code examples.

Preparation work:
Before we start, we need to do the following preparation work:

1. Register a Baidu developer account and obtain the App ID and key;
2. Install CURL extension in PHP environment.

PHP code example:
The following is a simple PHP code example to implement the German to English translation function.

<?php

// 设置百度翻译API接口地址
$url = 'https://fanyi-api.baidu.com/api/trans/vip/translate';

// 设置App ID和密钥
$appId = 'your_app_id';
$secretKey = 'your_secret_key';

// 设置待翻译的文本
$query = 'Hallo Welt!';

// 设定源语言和目标语言
$from = 'de';
$to = 'en';

// 生成随机数和签名
$salt = mt_rand(10000, 99999);
$sign = md5($appId . $query . $salt . $secretKey);

// 构建请求参数
$data = array(
    'q' => $query,
    'from' => $from,
    'to' => $to,
    'appid' => $appId,
    'salt' => $salt,
    'sign' => $sign
);

// 发送HTTP请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// 解析响应结果
$result = json_decode($response, true);
if (isset($result['trans_result'][0]['dst'])) {
    echo '源文本：' . $query;
    echo '目标文本：' . $result['trans_result'][0]['dst'];
} else {
    echo '翻译失败';
}

?>

Running results:
After executing the above code, we can get the following running result examples:

源文本：Hallo Welt!
目标文本：Hello World!

Summary:
By using PHP language combined with Baidu Translation API, we can easily Conveniently implement German to English translation function. This article provides simple code examples for developers to refer to and use. At the same time, Baidu Translation API also supports more language translations, and readers can expand and optimize according to actual needs. I hope this article can help everyone understand and use the PHP Baidu Translation API.
