php implements website staticization

With the continuous development of the Internet, the number of visits to the website is increasing, and the pressure on the server is also increasing. When you visit a large website, you will find that the loading speed is very slow, and you often need to wait several seconds or even ten seconds to open the page. Such waiting time will not only waste the user's time, but also affect the user's experience.

In order to solve this problem, many websites have begun to use website static technology to speed up website access. Website staticization refers to converting dynamically generated web pages into static HTML pages. This can reduce the pressure on the server, speed up page access, and improve user experience.

In development, PHP is a very popular website development language, which can easily generate dynamic web pages. At the same time, it also supports converting dynamic web pages into static web pages.

This article will discuss how to use PHP to realize the static function of the website. Let’s take a closer look below.

1. What is website staticization?

Website staticization refers to converting dynamic pages into static pages, that is, the server returns static HTML pages instead of executing background code to generate dynamic pages. For accessing the same page, you can directly return the same static page instead of querying from the database or file every time.

Static website has many advantages, such as:

1. Easy to cache, because static pages will not change and can be cached in memory, improving access speed.
2. Reduce the pressure on the server, because you don’t have to query from the database or file every time, which can reduce the pressure on the server.
3. Improve the access speed of the page, because you don’t need to execute the background code every time and can directly return to the static page.
4. Improve the user experience because the access speed is faster and users can get the information they need faster.
5. Improve the reliability of the website, because there is no need to execute the background code every time, which can reduce the possibility of failure, thus improving the reliability of the website.

2. How to achieve static website

There are many ways to achieve static website, among which the more commonly used ones are:

1. Static page generator

Use the static page generator to convert dynamically generated web pages into static HTML pages. Static page generators usually need to be configured so that they can generate static pages for specified pages.

2. Reverse proxy

Reverse proxy can convert dynamic pages into static pages. The reverse proxy server will cache these static pages and return them directly for the same request. The same static page, thereby improving access speed.

3. Template engine

The template engine supports converting dynamically generated pages into static HTML pages. When the client sends a request, the server will first query whether there is a generated static page. If it exists, it will directly return the static page, otherwise it will execute the subsequent code to dynamically generate the page.

You can choose any of the above methods according to actual needs. The following will focus on using template engines to achieve website staticization.

3. Use PHP to achieve website staticization

For websites developed using PHP language, you can use open source template engines such as Smarty to achieve website staticization. Smarty is a PHP-based template engine that separates the display of web pages from the back-end code, making the back-end code simpler and improving the maintainability of the page.

The following are the steps to use Smarty to convert dynamic pages into static pages:

1. Determine the pages that need to be accessed

The pages that need to be staticized It needs to be defined in Smarty's template first.

2. Determine whether the static page exists

In PHP, we can use the file_exists() function to query whether the static page exists.

If it exists, return the static page directly, otherwise execute the subsequent code to dynamically generate the page.

3. Generate static pages

In the application, we can write code to generate static pages. In general, content that is considered unchanged can be cached, including Content obtained from the database. If the form data is submitted in POST mode in the foreground, the cache needs to be cleared. You can consider clearing the cache through a scheduled script in the Linux system, or you can write code in PHP to implement it.

4. Return static pages

In PHP, we can use the header() and readfile() functions to return static pages.

Summary:

The above is a brief introduction to using PHP to achieve static website. Making the website static can increase the access speed of the website, thereby improving the user experience, reducing the load on the server, and improving the reliability and maintainability of the website. Therefore, website developers should always pursue best practices to ensure that website content can be presented to users in the fastest possible time.
