[转载] PHP用于生成html的类实例

最近在学习关于PHP如何生成html的方法，基本原理已经通晓，主要是使用fopen、fwrite、fclose、fread等函数实现。
考虑到程序功能的复用性，需要将程序封装为类，便于批量应用。
出于节省时间的目的考虑，在网上找到下面这串PHP生成html的类源码。

class html
{
    var $dir; //dir for the htmls(without/) 
    var $rootdir; //root of html files(without/):html 
    var $name; //html文件存放路径 
    var $dirname; //指定的文件夹名称 
    var $url; //获取html文件信息的来源网页地址 
    var $time; //html文件信息填加时的时间 
    var $dirtype; //目录存放方式:year,month,,,, 
    var $nametype; //html文件命名方式:name 
    
    
    function html($nametype = 'name', $dirtype = 'year', $rootdir = 'html')
    {
        $this -> setvar($nametype, $dirtype, $rootdir);
        }
    
    function setvar($nametype = 'name', $dirtype = 'year', $rootdir = 'html')
    {
        $this -> rootdir = $rootdir;
        $this -> dirtype = $dirtype;
        $this -> nametype = $nametype;
        }
    
    function createdir($dir = '')
    {
        $this -> dir = $dir?$dir:$this -> dir;
        
        if (!is_dir($this -> dir))
            {
            $temp = explode('/', $this -> dir);
            $cur_dir = '';
            for($i = 0;$i < count($temp);$i++)
