How to set up static in ThinkPHP5
1. What is staticization? Staticization is a means of converting dynamically generated content of web pages into static HTML files, allowing users to directly access static pages when accessing, thereby improving website performance. When a user accesses a dynamic page, the server will go through some processing, such as PHP parsing, database query, etc., before returning the page to the user. Staticization uses the caching mechanism to generate the page when the user accesses the dynamic page. Static files are cached on the server and user requests are redirected directly to the static files to reduce the load on the server. 2. Static settings in ThinkPHP5 There is no static function by default in ThinkPHP5, but you can
