How can PHP developers ensure that CSS files are properly loaded when using URL rewriting for subfiles in PHP?

When using URL rewriting for subfiles in PHP, the paths to CSS files may not be resolved correctly, leading to styling issues on the website. To ensure that CSS files are properly loaded, PHP developers can use the `$_SERVER['DOCUMENT_ROOT']` variable to generate the correct absolute path to the CSS files. 

<link rel="stylesheet" type="text/css" href="<?php echo $_SERVER['DOCUMENT_ROOT']; ?>/path/to/css/style.css">
