Can I create a vB php page outside of vBulletin?
 

I don't know if this is possbile or not but I'm trying to create a stand alone index.php file that contains some code for a Beach Tide Table. The trick is I want to use the vBulletin header, footer and navbar on the page so it looks consistent with the rest of my site. The Tide Table code has to be in the index.php file as it contains information for multiple locations that is refreshed when you click on the location you want. Here is the Tide Table link so you can see what I mean:

Any help is most appreciated!
