A simple template engine class, this class is only for research is not perfect, want to have friends to participate in learning research

The first time here, this code is mainly PHP template engine technology research, currently only compiled version, I hope you will provide advice and optimization skills three file composition, do not know how to file form, can only copy, sorry! index.php is a configuration file, folks, just look at it. index.html Some examples of use Templates.class.php base class Late release has a perfect version of the cache, but I hope not in the write cache some, a friend or expert guidance, the template engine as long as the processing of compilation and caching, the rest of the consideration is not considered, of course, the regular replacement mode to increase the f,w and the like ... Hope to have a friend can study my Q: 76376931 Copy_3_of_Templates.class.php file is already increased cache mode, refresh the page again does not generate the cache, regardless of whether some pages in the project to cache, later with the class in the gradual addition, I hope friends can communicate together!
