PHP-FPM performance improvement tips: Optimize website static resource loading

Abstract:
When building a high-performance website, optimizing static resource loading is crucial An important step. This article will introduce some PHP-FPM performance improvement techniques, focusing on methods to optimize the loading of static resources on the website. I'll introduce some specific code examples to help readers understand how to implement these optimizations.

Introduction:
With the development of the Internet, website speed and performance have become important factors that users and developers pay attention to. In a high-load environment, PHP-FPM's performance often becomes a bottleneck. Optimizing the performance of PHP-FPM can significantly improve the website's response speed and user experience, especially when loading static resources. Here are some specific methods to optimize the loading of static resources on your website.

1. Enable gzip compression
   Using gzip compression can reduce the file size of static resources, thereby speeding up loading. Configure gzip compression on the NGINX or Apache server:

gzip on;
gzip_comp_level 2;
gzip_min_length 1000;
gzip_proxied expired no-cache no-store private no_last_modified no_etag auth;
gzip_types text/plain text/css text/xml text/javascript application/json application/javascript application/x-javascript application/xml application/rss+xml application/atom+xml application/rdf+xml;
gzip_vary on;

2. Enable HTTP cache
   Enabling HTTP cache can speed up the loading of static resources and reduce requests to the server. This can be achieved by setting the Expires or Cache-Control header information:

location ~* .(js|css|png|jpg|jpeg|gif|ico)$ {
    expires 30d;
    add_header Pragma public;
    add_header Cache-Control "public";
}

3. Merge static resource files
   Merging multiple CSS or JS files into one file can reduce the number of HTTP requests . You can use the following code to combine multiple CSS files into one:

<?php
    $css_files = array('style1.css', 'style2.css', 'style3.css');
    $combined_css = '';

    foreach($css_files as $file) {
        $combined_css .= file_get_contents($file);
    }

    file_put_content('combined.css', $combined_css);
?>

Just reference the combined.css file in HTML.

4. Add version number or hash value to static resource URL
   When the content of the static resource file changes, we need to update the browser cache. To prevent browsers from caching older versions of static resources, you can add the version number or hash value to the file name:

<link rel="stylesheet" type="text/css" href="styles.css?v=1.1">

or use the MD5 hash value:

<?php
    $css_file = 'styles.css';
    $modified_time = filemtime($css_file);
    $hash = md5($modified_time);
    $new_file_name = 'styles_' . $hash . '.css';

    rename($css_file, $new_file_name);
?>

5. Use CDN to accelerate static resources
   Using CDN (content distribution network) can cache static resources to servers closer to users, thereby accelerating the loading of resources. You can use the following code to reference static resources on the CDN in your code:

<script src="//cdn.example.com/jquery.js"></script>
<link rel="stylesheet" type="text/css" href="//cdn.example.com/styles.css">

Conclusion:
By optimizing the loading of static resources on the website, the performance of PHP-FPM can be significantly improved, thereby speeding up the website. Loading speed and user experience. This article provides some specific code examples to help readers understand how to implement these optimization measures. I hope these tips will be helpful to readers when building high-performance websites.
