Detailed explanation of steps to staticize pages using PHP

This time I will give you a detailed explanation of the steps to use PHP page staticization. What are the precautions for using PHP page staticization? Here are practical cases, let’s take a look.

Page staticization, as the name suggests, is to convert dynamic PHP into static Html. The process is as follows

When the user accesses index.php, if index exists. html and within the validity period, directly output index.html, otherwise generate index.html

file_put_contents() output static file

ob_start() open PHP buffer

ob_get_contents() Get the buffer contents

ob_clean() Clear the buffer

ob_get_clean() Equivalent to ob_get_contents( ) ob_clean()

Code example

<?php if (file_exists(&#39;./html/index.html&#39;) && time() - filectime(&#39;./html/index.html&#39;) < 30) {
 require_once &#39;./html/index.html&#39;;
} else {
 // 引入数据库配置
 require_once "./config/database.php";
 // 引入Medoo类库
 require_once "./libs/medoo.php";
 // 实例化db对象
 $db = new medoo($config);
 // 获取数据
 $users = $db->select('user', ['uid', 'username', 'email']);
 // 引入模板
 require_once "./templates/index.php";
 // 写入html
 file_put_contents('./html/index.html', ob_get_contents());
}
