    If(($UploadFile !="none" ))
    {  
        $UploadPath=AddSlashes(dirname($PATH_TRANSLATED))."\my_files\"; //上载文件存放路径

        $FileName=$UploadPath.$UploadFile_name; //上载文件名

        if($UploadFile_size < 1024) //上载文件大小
        {
      $FileSize=(string)$UploadFile_size." 字节"; 
     }
         elseif ($UploadFile_size <(1024 * 1024))

      $FileSize=number_format((double)($UploadFile_size/1024), 1) . " KB";
         }
      else{
      $FileSize=number_format((double)($UploadFile_size / (1024 * 1024)), 1) . " MB";
         }
       
        if(!file_exists($FileName))
        {
             if(copy($UploadFile,$FileName))
             {  echo "文件 $UploadFile_name ($FileSize)上载成功！"; }
             else
             { echo "文件 $UploadFile_name上载失败！"; }

             unlink($UploadFile);
        }
        else
        { echo "文件 $UploadFile_name已经存在！"; }
    }
