How to achieve static splicing web page effect in php

In web development using PHP, we usually use dynamic page generation to display different content. However, in some scenarios, we need to use static web pages to improve page access speed and reduce server load. At this time, static splicing web pages is a good choice.

Static splicing web pages refers to combining several HTML pages into a single page. This method can greatly improve the response speed of the page, because all data is processed in advance and does not need to be recalculated every time the page is requested.

In PHP, there are many methods to achieve the effect of static splicing web pages. Two of them will be introduced in detail below.

Method 1: Use ob_start() and ob_get_contents()

The ob_start() function can start output buffering without sending the content to the client. When all the contents have been processed, you can use the ob_get_contents() function to obtain the buffer contents, and then clear and close the buffer.

The following are the basic steps to use ob_start() and ob_get_contents() to implement static splicing of web pages:

1. Use the ob_start() function to start the output buffer.
2. Use the include() or require() functions to include other HTML pages and output their contents to a buffer.
3. Use the ob_get_contents() function to get the contents of the buffer, and clear and close the buffer.
4. Save the obtained content as an HTML file.

The following is a simple sample code:

<?php   // 启动输出缓冲区
  ob_start();

  // 包含其他 HTML 页面
  include(&#39;header.html&#39;);
  include(&#39;main.html&#39;);
  include(&#39;footer.html&#39;);

  // 获取缓冲区中的内容
  $content = ob_get_contents();

  // 清空缓冲区
  ob_end_clean();

  // 保存为 HTML 文件
  file_put_contents(&#39;static.html&#39;, $content);
?>

Method 2: Use file_get_contents() and file_put_contents()

file_get_contents() The function can read the entire contents of a file and return a string. The file_put_contents() function writes a string to the specified file. Using these two functions, you can read the contents of multiple HTML files, concatenate them into a single string, and then save them as an HTML file through the file_put_contents() function.

The following are the basic steps to use file_get_contents() and file_put_contents() to implement static splicing of web pages:

1. Use the file_get_contents() function to read the content of other HTML pages and splice them is a string.
2. Use the file_put_contents() function to save the string as an HTML file.

The following is a simple sample code:

<?php   $header = file_get_contents(&#39;header.html&#39;);
  $main = file_get_contents(&#39;main.html&#39;);
  $footer = file_get_contents(&#39;footer.html&#39;);

  $content = $header . $main . $footer;

  file_put_contents(&#39;static.html&#39;, $content);
?>

In summary, static splicing of web pages is an effective method to improve page response speed and reduce server load. In PHP, the effect of statically splicing web pages can be achieved by using the ob_start() and ob_get_contents() or file_get_contents() and file_put_contents() functions.
