How to achieve translation in php?

PHP realizes translation function

Today we talk about using PHP to realize translation function. Of course, PHP is definitely not a language that can become a translator. We need to use professional The program that translated this matter gave us an open API interface to obtain data, and finally handed it over to PHP to parse the data and display it on the platform we need.

Everyone should know that Youdao Translation is one of the better translation platforms in China. Today we will use its open interface to learn. Let’s start explaining the code.

     <?php
          function transLate($word){
               // keyfrom和apikey是有道开放平台提供的
               // 大家去这里注册即可获得：http://fanyi.youdao.com/openapi
       $keyfrom = "******";
       $apikey = "******";     
                 
       // 通过有道翻译json格式来显示传值
       $url_youdao = &#39;http://fanyi.youdao.com/fanyiapi.do?keyfrom=&#39;.$keyfrom.&#39;&key=&#39;.$apikey.&#39;&type=data&doctype=json&version=1.1&q=&#39;.$word;
               // 利用PHP自带的函数，抓取URL返回的json数据
       $json = file_get_contents($url_youdao);
      // 说明：假如是写成$obj = json_decode($json,true);
              // 则此时obj就是一个数组
              // 但是不加true，则是将json数据转换成对象类的形式，即返回的是对象。
      $obj = json_decode($json);
        
              // 得到返回码 
      $errorCode = $obj->errorCode;      
 if(isset($errorCode))
 {
switch ($errorCode) 
{
case 0:        // 说明返回的数据正常 
$trans = $obj->translation[0];     
break;
case 20:
$trans = &#39;要翻译的文本过长&#39;;
break;
case 30:
$trans = &#39;无法进行有效的翻译&#39;;
break;
case 40:
$trans = &#39;不支持的语言类型&#39;;
break;
   case 50:
$trans = &#39;无效的key&#39;;
break;
default:
$trans = &#39;出现异常&#39;;
break;
}
  }
  return $trans;
}
        // 测试"英翻汉"或者"汉翻英"都可以
echo transLate(&#39;很高兴认识你&#39;);
echo transLate(&#39;Nice to meet you&#39;);
?>

In fact, there are many cases of using PHP to parse the open API interface to obtain data. I will share it with you slowly in the future!
