How to achieve translation from Portuguese to Arabic through PHP Baidu Translation API?

With the development of globalization, cross-language communication has become more and more common. In order to meet the translation needs between different languages, many translation APIs are now available. This article will introduce how to use the PHP programming language and Baidu Translation API to achieve translation from Portuguese to Arabic.

First, we need to create a developer account on the Baidu Translation Open Platform and obtain the key to access the API. After logging in to the Baidu Translation Open Platform, find the "My Applications" page and click the "Create Translation Application" button. During the process of creating the application, we need to select "Universal Translation API" as the API type and set a name and description for the application. After creation, we will get an App ID and a key, which will be used in the code.

Next, we can use PHP to write code to call Baidu Translation API. First, we need to introduce an HTTP request library, such as Guzzle, into the code to help us send HTTP requests. It can be installed through Composer, running the following command:

composer require guzzlehttp/guzzle

We can then create a PHP script to do the translation. First, we need to set some necessary parameters, including App ID, key, text to be translated and source language, target language, etc. You can set it up according to the following code example:

<?php

require 'vendor/autoload.php';

$appId = 'your_app_id';
$key = 'your_app_key';
$text = 'texto de exemplo'; //待翻译的文本
$from = 'pt'; //源语言为葡萄牙语
$to = 'ar'; //目标语言为阿拉伯语
$url = 'http://api.fanyi.baidu.com/api/trans/vip/translate';

$salt = rand(10000, 99999);
$sign = md5($appId . $text . $salt . $key);

$client = new GuzzleHttpClient();

$response = $client->request('GET', $url, [
    'query' => [
        'q' => $text,
        'from' => $from,
        'to' => $to,
        'appid' => $appId,
        'salt' => $salt,
        'sign' => $sign
    ]
]);

$translation = json_decode($response->getBody()->getContents(), true)['trans_result'][0]['dst'];

echo "原文：".$text;
echo "翻译结果：".$translation;

In the above code, we use the Guzzle library to send a GET request to the URL of the Baidu Translation API. In the request, we pass the necessary parameters in the form of a query string and generate a signature using the App ID, text, nonce, and secret key. Finally, we parse the JSON response returned by the API and extract the translation results.

Run the above code, we can see the Arabic translation results of the Portuguese text.

Through the above code examples, we can easily implement the translation function from Portuguese to Arabic. By using PHP and Baidu Translation API, we can easily translate between multiple languages ​​and facilitate cross-language communication.
