PHP 调用百度翻译接口代码示例

php调用百度翻译最新接口代码，调用的方式有少许的变化。具体可以查看百度接口文档。对翻译的值不需要再经过urlencode转化，翻译时需要验证签名。具体的代码如下：

function language($value,$from="auto",$to="auto")
{
     $value_code = $value; //urlencode($value); //首先对要翻译的文字进行 urlencode 处理
     $appid = "20151119000000001"; //您注册的API Key
     $key = "12345678"; //密钥
     $salt = rand(1000000000,9999999999); //随机数
     $sign = md5($appid.$value_code.$salt.$key); //签名
     //生成翻译API的URL GET地址
     $languageurl = "http://api.fanyi.baidu.com/api/trans/vip/translate?q=$value_code&appid=$appid&salt=$salt&from=$from&to=$to&sign=$sign";

     $text=json_decode(LanguageText($languageurl));
     return $text->trans_result;
}

function LanguageText($url) //获取目标URL所打印的内容
{
     if(!function_exists('file_get_contents'))
     {
          $file_contents = file_get_contents($url);
     } else {
          $ch = curl_init();
          curl_setopt ($ch, CURLOPT_URL, $url);
          curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
          curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
          $file_contents = curl_exec($ch);
          curl_close($ch);
     }
     return $file_contents;
}
// echo language('中国', 'zh', 'en');



$val = $post['val'];
$lan = language($val, 'zh', 'en');
$result = '';
foreach ($lan as $k => $v)
{
     $result .= ucwords($v->dst) ."\n";
}
echo json_encode($result);
exit();
