However, sometimes, when users visit the PHP page, the CSS style seems to be invalid, resulting in confusing page layout and even affecting the user experience.

When referencing CSS style files in PHP files, make sure the path is correct. If the CSS style files are not in the same directory as the PHP files, you need to take path issues into account.

For example, the server may not have the MIME type configured correctly, causing the style file to not be recognized correctly. In this case, you need to contact your server administrator and confirm whether the server has correctly configured MIME types, etc.

Summary
