Why does php cancel subdirectory structure compression? How to cancel?

For web developers using PHP, it is often necessary to compress static resources to improve website access speed. A common compression method is to merge multiple files into one file and then compress it. Although this method can effectively reduce the number of requests and improve page loading speed, if the subdirectory structure is included during the compression process, it will cause many unnecessary problems. Therefore, this article aims to introduce how to cancel subdirectory structure compression to improve the development efficiency of PHP developers.

1. Why should you cancel subdirectory structure compression?

When using compression tools, such as YUI Compressor, all JS and CSS files will be compressed by default and they will be Merged into one file. However, if our project contains a relatively large number of subdirectories, then in the merged file, code similar to the following will appear:

/* /user/css/main.css */
body {
    background-color: #f0f0f0;
}

/* /user/js/javascript.js */
$(document).ready(function() {
    console.log("Ready");
});

This will cause a problem: when you are in the page When a merged CSS or JS file is introduced, the browser will not correctly recognize the styles or scripts in the file because the path to the file has been incorrectly compressed.

2. Solution to cancel subdirectory structure compression

In order to solve this problem, we need to follow the following steps to cancel subdirectory structure compression:

1. First, we need to use a custom merge script instead of using the default compression tool.
2. Secondly, in the merge script, we need to formulate a new file path for each JS or CSS file to ensure that the path information in the compressed merged file is correct. For example:

/* /user/css/main.css */
body {
    background-color: #f0f0f0;
}

/* /user/js/javascript.js */
$(document).ready(function() {
    console.log("Ready");
});

We need to replace it with the following code:

/* /static/css/main.css */
body {
    background-color: #f0f0f0;
}

/* /static/js/javascript.js */
$(document).ready(function() {
    console.log("Ready");
});

In this way, in the compressed merged file, the style and script paths are correct and can be used normally.

3. Summary

In projects, in order to improve the access speed of the website, we usually need to reduce the number of requests by merging static resource files. However, when using compression tools and including subdirectories, you need to pay attention to path issues, otherwise the page will not load correctly. Therefore, this article explains how to uncompress subdirectory structures to avoid path problems.
