最近工作需要，在进行机翻的尝试，整理了一下Google和Bing的API，现在将相关代码贴出来：

    protected $api   =   null;  
    private $source_lang = 'zh-cn';  
    private $target_lang = 'en';

public function __construct($api, $from = 'zh-cn', $to = 'en', $other = ''){  
        $filename = LIB_PATH . '/Driver/Translate/' . ucwords($api) . '.class.php';  
        if(file_exists($filename)) {  
            include_once $filename;  
        } else {  
            throw Exception($api . ' is not found!');  
        }  
        if($from) {

            $this->target_lang = $to;  
        }  
        $class = 'translate'.ucwords($api);  
        $this->api = new $class($this->source_lang, $this->target_lang, $other);  
    }

public function getError() { 
 return $this->api->getError(); 
 }
