Web Page Global Changes

Is there a way to make a global change to ALL pages on a web site that have been created from the same basic template?

As my site grows, any change to the main menu is adding up to a lot of work!
I understand the use of CSS to make a global style change...but what content like the entire main menu?

If you have php on your server, You could include the file:

PHP Code:

---

<?php
include 'your-file.php';
?>

---

Please post if you need any more help.

In case you're using .html extensions and don't want to change all your pages you can take a look at this thread:
