Rename your CSS file to end in .php,
将您的 CSS 文件重命名为以.php,
styles.css -> styles.php
However, I doubt that you really need to have PHP code in a CSS file.
但是，我怀疑您是否真的需要在 CSS 文件中包含 PHP 代码。
Good point from the comments below, place
下面评论的好点，地方
<?php header("Content-type: text/css"); ?>
at the top of the file.
在文件的顶部。

Unless it's a terrible lot of dynamic values, it is much better to have a static CSS file, and override only those parts that change dynamically inside the document where PHP is running already anyway. It saves you a request (plus the time needed for bootstrapping etc.), and makes the majority of the style sheet cacheable.
除非它有大量的动态值，否则最好有一个静态 CSS 文件，并且只覆盖那些在 PHP 已经运行的文档中动态变化的部分。它为您节省了一个请求（加上引导等所需的时间），并使大部分样式表可缓存。
In your PHP/HTML page's head section:
在您的 PHP/HTML 页面的头部部分：
<!-- static resource -->
<link rel="stylesheet" href="styles.css">
<!-- Dynamic styles -->
<style type="text/css">
body { color: <?php echo $body_color; ?>; }
h1 { font-size: <?php echo $fontsize."px"; ?>; }
p { color: <?php echo $paragraph_color; ?>; }
</style>

Putting PHP code in a CSS file will not work. You will have to create a PHP file first, and let that output CSS code. And also set the correct content type headers.
将 PHP 代码放在 CSS 文件中是行不通的。您必须先创建一个 PHP 文件，然后让该文件输出 CSS 代码。并设置正确的内容类型标题。
<?php
header('Content-type: text/css');
$color = "#ff6600";
?>
body {
color: <?=$color?>
}
...
