As we all know, most website news or product information is static pages. The main benefits of doing so are: 1. speed up access and avoid excessive database operations; 2. SEO optimization to facilitate search engine indexing.

This example describes how to generate static html in batches based on the CMS static page solution.

Note: This program can only run in Windows DOS or Linux by executing the PHP command.

In this example, there are four files: config. inc. php (configuration file), Db. class. php (database PDO class), Model. class. php (PDO database operation class), index. php (execution file)
