Javascript – Trouble including .js file into php


I am trying to include a .js file into a php file.
My folder structure looks like this:

---js (FOLDER)
---blog (FOLDER)
------js (FOLDER)

If I am using this:

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

it works just fine.

What I can't seem to do is include file.js from under the root's "js" directory.
I've tried everything I can think of but I just can't seem to make it work.

Best Solution

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

would reference the javascript file in the top level js directory
