How to use PHP Baidu Translation API to translate German to Chinese?
Introduction:
In today's era of globalization, language communication has become an important issue. When we encounter a language we don’t understand, we can use translation tools to solve this problem. Baidu Translation API is a powerful tool that can help us achieve translation in multiple languages. This article will introduce how to use the PHP Baidu Translation API to achieve German to Chinese translation.
Preparation work:
First, we need to register a Baidu Translation developer account and apply for an API Key. After the registration is completed, we can obtain the API Key and Secret Key. This information will be used in subsequent code examples.
Step 1: Install the necessary components
First, we need to make sure that PHP, as well as curl and openssl extensions are installed on our server. You can check whether these components have been installed by running the following command:
php -m | grep -i curl php -m | grep -i openssl
If no output is displayed, it means that the corresponding components are not installed. These components can be installed through the following command:
sudo apt-get install php-curl sudo apt-get install php-openssl
Step 2: Write PHP script
Next, we create a PHP file, such as translate.php
, and write the following code:
<?php function translate($query) { $app_id = 'your_app_id'; // 在此替换成你的App ID $api_key = 'your_api_key'; // 在此替换成你的API Key $secret_key = 'your_secret_key'; // 在此替换成你的Secret Key $salt = rand(10000, 99999); $sign = md5($app_id.$query.$salt.$secret_key); $url = 'http://api.fanyi.baidu.com/api/trans/vip/translate'; $params = [ 'q' => $query, 'from' => 'de', 'to' => 'zh', 'appid' => $app_id, 'salt' => $salt, 'sign' => $sign, ]; $url = $url . '?' . http_build_query($params); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 10); $result = curl_exec($ch); curl_close($ch); $result = json_decode($result, true); return $result['trans_result'][0]['dst']; } $input = 'Hallo Welt'; // 德语输入 $output = translate($input); // 翻译后的中文 echo '输入:' . $input . PHP_EOL; echo '输出:' . $output . PHP_EOL; ?>
In the above code, we first define the translate
function for actual translation operations. Inside the function, we first obtain the API Key and Secret Key, and generate a salt value through a random number. Then, we generate a signature based on the request parameters. Next, we build a complete API request URL and send the request using the curl
library. Finally, we parse the JSON result returned by the API and return the translated text.
In the sample code, we define an input string Hallo Welt
, and then call the translate
function to perform the translation operation and output the result.
Step 3: Run the code
Save the above PHP script. We can run this script through the command line or browser. In the command line, we can run it through the following command:
php translate.php
Or, enter the URL address of the script in the browser, such as http://localhost/translate.php
to run it script.
After running the code, we can see the following output:
输入:Hallo Welt 输出:你好世界
This is the result of using the PHP Baidu Translation API to achieve German to Chinese translation.
Summary:
Through the above steps, we successfully used the PHP Baidu Translation API to achieve German to Chinese translation. I hope this article will be helpful to you and make it easier for you to solve language communication problems. If you need translation into other languages, just modify the parameters in the code.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
