How to properly connect files to php?

Question

PHP

I need to include other files in php, in this case css and js. include outputs their contents, but not the processed request. How can I organize this? Executing scripts, not outputting code...

Answer 1

echo '<link rel="stylesheet" href="main.css">'

Answer 2

css - generally html=headers - no? And scripts anywhere on the page can be connected like this construction -

<script type="text/javascript" src="scr.js"></script>
