Discuss the static method in PHP

With the rapid development of the Internet, the number of website visits is increasing, and the performance of the website has become one of the important issues that designers need to consider. For developers using the PHP language, staticization is an effective way to improve website performance. In this article, we will explore the methods of staticization in PHP.

1. What is staticization

Staticization refers to converting dynamically generated web page files (such as PHP files) into static HTML files and storing them on the server. When a user makes a request, the static HTML file is directly accessed, avoiding the need to execute PHP code for each request, thus improving the performance and response speed of the website.

2. Advantages and Disadvantages of Staticization

Although staticization can improve the response speed of the website, it also has some defects:

Advantages:

1 . Reduce server pressure: After staticization, user requests will directly access the HTML files on the server, without the need for PHP code execution. This reduces the pressure on the server and improves the server's performance processing capabilities.

2. Improve access speed: Staticization can avoid the need to execute PHP code for every request, thereby improving the performance response speed of the website.

Disadvantages:

1. Cannot be updated in real time: Since static HTML files are generated in advance, when the website content needs to be updated, it cannot be immediately reflected in the static files and needs to be updated manually.

2. Waste of space: Static HTML files are stored on the server and require a certain amount of disk space. If the website content is updated frequently, a large number of static HTML files need to be generated, which takes up a lot of disk space.

3. Difficulty adapting to personalized needs: Static HTML files are universal and cannot achieve personalized display, resulting in less effective access than dynamically generated web pages.

3. How to achieve staticization

For the PHP language, there are two ways to achieve staticization: one is manual staticization, and the other is to use the staticization that comes with the PHP framework. Function.

1. Manual staticization

Manual staticization is to manually convert dynamically generated PHP files into static HTML files. Here are the specific methods of manual staticization:

(1) Manually create a directory for storing static HTML files;

(2) In the PHP file, use the PHP file operation function Write the page data into the static file;

(3) Modify the website link and change the original PHP link to an HTML link.

The advantage of manual staticization is that it is simple to implement and suitable for small-scale websites. However, a large amount of code needs to be written manually, and static files need to be updated manually, which is relatively inefficient.

2. Use the static function that comes with the PHP framework

At present, most PHP frameworks provide their own static function, such as Discuz, WordPress, ThinkPHP, etc., which can be used in the framework In the configuration, set whether to enable the static function, and use the static plug-in that comes with the framework to achieve static conversion of dynamic web pages.

Taking the ThinkPHP framework as an example, you can achieve static page by using a static plug-in in the controller:

protected function buildHtml($id,$htmlfile,$template){
    ob_start();
    //下面这一行代码为控制器加载模板文件
    $this->display($template);
    //将当前页面内容保存到$contents中
    $contents=ob_get_contents();
    //将$contents中的数据写入到静态的HTML文件中
    file_put_contents($htmlfile,$contents);
    ob_end_clean();
}

When the user requests the corresponding page, the static plug-in will determine whether There is a corresponding static file. If there is, the static file is returned directly; if not, PHP is first called to dynamically generate data, and then the data is written into the static file and returned to the user.

4. Summary

In summary, staticization is an effective way to improve website performance. We can achieve static operations through manual staticization or using the staticization function that comes with the PHP framework. Staticization can not only improve response speed and reduce server pressure, but also improve user experience. Of course, staticization also has some shortcomings. We need to choose whether to use staticization technology based on specific business needs.
