PHP Quick URL Rewrite instance code

More than 5.30 of the version can be used, inherited the characteristics of the previous version of the fast redirection (separate classes, all using static calls), add a very important function and properties, can invoke other URLs in the module, but also the module and the module or the function of the page and the page to simplify the sharing can be implemented. htaccess file notation: #--------------. htaccess start--------------- Rewriteengine on Rewriterule!.
