Opening and setting up the rewrite module of apache is not the subject of this article. Please see other articles for detailed explanations.
This class can only be used in versions above PHP 5.30. It inherits the characteristics of fast redirection from the previous version (single class, all Using static calling), a very important function and attribute is added to call modules in other URLs, which also enables simplified sharing of functions between modules or between pages.

Introduction of rewriting function: write the following code at the end of index.php in the root directory of the site, and rewriting will be enabled (normal conditions: 1.
