How to generate static files in PHP to relieve server pressure

Server load is an important consideration when developing web applications. When a large number of users visit a website, dynamically generating content can put a lot of pressure on the server. In order to alleviate the load on the server, a common method is to save the dynamically generated content as a static file and then directly provide it to the user for access instead of dynamically generating it every time.

Below I will introduce a method to generate static files in PHP.

1. Check whether static files exist

When each request reaches the server, it first needs to check whether the corresponding static file already exists. If it exists, the static file is returned directly; if it does not exist, the subsequent dynamic generation logic continues to be executed.

$staticFilePath = 'path/to/static/file.html';

if (file_exists($staticFilePath)) {
   
    
    
    // 静态文件存在，
