Easy Change Sidenav?

So on my side nav i have a server list that i will be currently updating but when i have over 50 pages it would be a pain to have to go to every page and update it so i was wondering if there was anyway that i can use a css style or somthign that i could put between my DIVS that would show w.e is in the external link. That way i could go to say a file named Serverlist and i could change that which would update every page on my site. So if anyone has any ideas that would be great. I know Webs has something like this for there sidenavs and id like somthign like that. Thanks

Hello tissue,
It sounds like your looking for a server side include. Have a look at this tutorial (http://www.tizag.com/phpT/include.php) and see if it won't do what you're wanting.

omg thank you. i knew id have to learn some php for this so ive been doing some tutorials. Just didnt know which things to use. Thanks
