      $filenamedoc = dirname(__FILE__)."/".$wordPath;
      $filenamepdf = dirname(__FILE__)."/".$outPath;
      
      // 删除已有同名文件
      if(file_exists($filenamepdf)) 
      {
          unlink($filenamepdf);
      }
      
      // 执行转换操作
      $word = new COM("word.Application") or die("Could not initialise Object");
      $word->Documents->Open($filenamedoc);
      $word->ActiveDocument->ExportAsFixedFormat($filenamepdf, 17, false, 0, 0, 0, 0, 7, true, true, 2, true, true, false);
      $word->Quit(false);
      unset($word);
      
      // 在页面中显示生成的pdf
      // header('Content-type: application/pdf');
      // header('filename='.$filenamepdf);
      // readfile($filenamepdf);
      
      return '转换成功';
