PHP bulk Generation static html_php tutorial

As we all know, most of the Web site news or product information are static pages. The advantages of this is mainly to: 1, speed up access, avoid excessive operation of the database; 2, SEO optimization, easy search engine included.

This example starts with a static page scheme for the CMS system and shows the bulk generation of static HTML functionality.

Note: This program can only be run under Windows DOS or Linux execution PHP commands.

This sample has 4 main files: config.inc.php (config file), Db.class.php (Database PDO Class), Model.class.php (PDO Database Operations Class), index.php (execute file)
