ThinkPHP调用百度翻译类实现在线翻译_php实例

要实现ThinkPHP在线翻译功能，需要先在百度开发者中心注册一个API key，具体实现代码如下：

action代码部分：

display("Public:404"); 
  }
public function index()
{
$User = A("Index"); 
$User->head();
$User->right();
$User->footer();
$this->display();
}
public function fanyi()
{
$value=$_POST['value'];
$from="auto";
$to="auto";
$value_code=urlencode($value); 
$appid="xxxxxxxx";//这里填写你在百度上申请的API key  
$languageurl = "http://openapi.baidu.com/public/2.0/bmt/translate?client_id=" . $appid ."&q=" .$value_code. "&from=".$from."&to=".$to;
$text=json_decode($this->language_text($languageurl)); 
$text = $text->trans_result; 
$rs=$text[0]->dst;
$this->assign('value',$value);
$this->assign('rs',$rs);
$User = A("Index"); 
$User->head();
$User->right();
$User->footer();
$this->display(index);
}
public function language_text($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(); 
$timeout = 5; 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
$file_contents = curl_exec($ch); 
curl_close($ch); 
}  
return $file_contents;
}
}
?>

html代码部分：

原文：
{$value}

译文：
{$rs}
