I want to include a css file into the head section of a php file ?
Right now I am including css in this way:

```
<?php include('./includes.header.html'); ?>
<style><?php include('./test.css'); ?> </style>

```

What it does is it includes the css in the body section not in the head section.
I have no idea to add js file before the end of body tag.
Please tell me a way to include the css file in the head section and js file before the end of the body tag.
Thanks in advance.
