文件3：TemplateParser.php
上面的模板解析类是笔者一时写的一个复杂的模板解析类，功效很少，没有真正甚么利用价值。然而在这里可以知足这篇文章解说的需求。
同时，假如之前没有接触过模板解析，对模板解析的完成办法有必定疑问的同寅，可以研讨一下这个复杂类完成解析的体例，代码挺复杂的应当能看懂的。
这个解析类有本人的模板布局，“块”(要停止轮回显示的中央)的界说以下：
BEGIN_你的块名_
......html代码.......
_你的块外面的变量的称号_
......html代码.......
END_你的块名_
变量的界说体例以下：
......html代码.......
_你的块外面的变量的称号_
......html代码.......
详细的“块”和“变量”的利用参考下面的两个模板
