How to create a php header with different css and js?

Question

Quick and should be simple question, but i cant find the answer!!! So im trying to make a universal header called header.php. Now the only problem is that some pages have 5 css style sheets while others have only 2. And some pages have 5 js links in the header while some only have 1. How do i account for this variability in css and js links in the header? Am i suppose to use if statments? Variables? Thanks!

Consider combining resources to single ones. This will minimize HTTP requests which is a good practice.
