静态|网页|原创

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.
