php+mysql存儲html文件

                $fileContent = trim($fileContent);

                $fileContent=$queueList->characet($fileContent);

                $fileContent = addslashes(htmlspecialchars($fileContent,ENT_QUOTES,'UTF-8'));

characet如下:
    public function characet($data){

      if( !empty($data) ){   

        $fileType = mb_detect_encoding($data , array('UTF-8','GBK','LATIN1','BIG5','gb2312')) ;

        if( $fileType != 'UTF-8'){  

          $data = mb_convert_encoding($data ,'utf-8' , $fileType);  

        } 

      }  

      return $data;   

    }

讀取如下:
htmlspecialchars_decode(stripslashes($res['content']),ENT_QUOTES)
