   有很长一段时间我到处问别人怎么实现静态网页,还向唠叨提过问题,而如今,我终于想出了一个很简单的办法,那就是用libtemplate来实现它。
  大家看:http://doc.iwind.org
  下面我就如何实现静态网页输出谈一谈。
  1,修改libtemplate.
  加入两个函数
  //将分析结果保存到文件中去
  function savetofile ($dir,$varname){
   $data=$this->finish($this->get_var($varname));
   $fp=fopen($dir,"w+");
   fwrite($fp,$data);
  }
  函数中的dir是我们要保存在文件的地方。varname则是libtemplate中$target,使用如下:
   $tpl->set_file("main","main.tpl");
   ...
   $tpl->parse("mains","main");
   $tpl->savetofile("html/main.html","mains");
  相信懂libtemplate的读者很容易理解这些.
  //清除已赋值数组
   function renew(){
    $this->varkeys=array();
    $this->varvals=array();
    $this->file=array();
    }
  这样就可以清除前面模板分析的影响.
2,实现静态输出.
   如果输出的是单文件正如上面的一个例子.
     $tpl->set_file("main","main.tpl");
   ...
   $tpl->parse("mains","main");
   $tpl->savetofile("html/main.html","mains");
    
    但一旦我们更改了文章显示的模板,如何使以前生成的静态网页如何快速更新呢?显然要循环输出.例子如下:
    html_info(){//单个文件,只是一个相似的例子  
      global $tpl;  
      $tpl->set_file("main","main.tpl");
     ...
     $tpl->parse("mains","main");
     $tpl->savetofile("html/main.html","mains");
     $tpl->renew();//至关重要
   }
  //循环输出
    for($i=0;$i         ...
         html_info;
      }
   所以说实现生成静态页面是很简单的.更新也非想象中那么复杂.
