How to import/include a CSS file using PHP code and not HTML code?

Question

I have googled a lot but it seems that I am doing something wrong.

I want to do this:

<?php
include 'header.php';
include'CSS/main.css';
...
?>

However, my page prints the CSS code.

Note: I want to use PHP to include the CSS file, and not use I also do you want to rename my CSS file to a PHP file as some website mentioned.

Any clues?

Many thanks.

You have to surround the CSS with a <style> tag:

<?php include 'header.php'; ?>
<style>
<?php include 'CSS/main.css'; ?>
</style>
...

PHP include works fine with .css ending too. In this way you can even use PHP in your CSS file. That can be really helpful to organize e.g. colors as variables.
