php static data methods include: 1. Caching system. Commonly used PHP caching systems include Memcached, Redis, etc.; 2. Static file generation, using PHP's file_put_contents() function to output the page content to the specified HTML file; 3. Static file caching can convert dynamic requests into static requests and store the results on the server for subsequent access; 4. Pre-rendering technology can solve the problem of dynamically generated pages not being included by search engines. , improve the SEO effect of the page.

In PHP development, generating static data is a very common requirement. Using static data can improve website performance and reduce database access pressure. PHP provides a variety of ways to generate static data, and several common ways will be introduced below.
1. Caching system: The most commonly used way to generate static data in PHP is through the caching system. The caching system saves dynamically generated pages on the server so that the next time you access the same page, you can directly return to the static page, thereby speeding up page loading. Commonly used PHP caching systems include Memcached, Redis, etc. These systems enable fast access by storing data in memory and can set expiration times to ensure timely updates of data.
2. Static file generation: Another common way to generate static data is to generate static HTML files through PHP code. In pages that need to generate static data, you can use PHP's file_put_contents() function to output the page content to the specified HTML file. The HTML files generated in this way can be accessed directly without executing PHP code, thereby improving page loading speed. It should be noted that if the page content needs to be updated in real time, the static file needs to be regenerated when the page content changes.
3. Static file caching: In addition to generating static files, server-level static file caching can also be used to generate static data. Common server-level static file caches include Nginx's FastCGI cache, Apache's mod_cache, etc. These caching modules can transform dynamic requests into static requests and store the results on the server for subsequent access. By using these caching modules, you can reduce the number of executions of PHP code and improve the processing speed of requests.
4. Pre-rendering technology: Pre-rendering technology can execute JavaScript code through the browser engine on the server side to generate a complete static HTML file. Common pre-rendering technologies include Prerender, Puppeteer, etc. These technologies can simulate user behavior, execute JavaScript code in the page, and save the execution results as complete static HTML files. Through pre-rendering technology, the problem of dynamically generated pages that cannot be indexed by search engines can be solved and the SEO effect of the page can be improved.
To sum up, there are many ways to choose from when generating static data in PHP. Depending on the actual needs and development environment, you can choose an appropriate method to generate static data. Whether you use a caching system, generate static files, or use server-level static file caching, you can increase page loading speed and improve user experience. During the development process, you can choose a suitable method according to specific requirements to achieve efficient and stable static data generation.
