Need some help making my PHP code echo something else

[DigitalSky]

Okay, here is the code I've written below. What it does is it determines if you're on a specific page URL and depending on the URL you're on it will echo some particular HTML code which is exclusive to that page (or set of pages).

It works perfectly so far but one thing I wanted it to do (which I don't know how to do at the moment) is that I want it to echo some other HTML code if a particular page is not found in ago of those 'case' statements.

So for instance, if I have a bunch of URLs that aren't in the code below I want it to default to echoing something other HTML code. Make sense?

Anyhow, here is my code...

<?php

switch($_SERVER['REQUEST_URI']) {
case '/about-us/':
    case '/faa-advisory/':
case '/policies/';
case '/contact-us/';
    echo
'I plan on putting some HTML code here';

    break;

    case '/shop/category/bird-diverters/';
case '/shop/firefly-hw-bird-diverters/';
case '/shop/firefly-ff-bird-diverters/';
case '/shop/firefly-wm-bird-diverters/';
    echo
'I plan on putting some different HTML code here';

    break;

}

?>

Instead of case you use default such as:

switch($a) {
case '1': echo 'One'; break;
case '2': echo 'Two'; break;
default: echo 'everything else'; break;
}

Worked like a charm! Thank you so much!
