What are the potential pitfalls of setting cookies within a CSS file in PHP?

Setting cookies within a CSS file in PHP can lead to unexpected behavior and potential security risks. It is not recommended to mix cookie setting with CSS styling. To avoid this issue, cookies should be set in PHP files that handle logic and data manipulation, separate from CSS files. 

<?php
// Set cookie in a PHP file, not within a CSS file
setcookie("user", "John Doe", time() + 3600, "/");
?>
