I have a website that I need some help with in terms of php. What I want to do is show that each page has valid XHMTL and CSS.

Here's the code that I have now.

Code:
<div id="footer">
        <h2>Footer information including bottom navigation</h2>
        <a href="index.php">Home</a> | <a href="index.php/about-us">About</a> | <a href="index.php/beer-selection">Beer Selection</a> | <a href="index.php/beer-information">Beer Info</a> | <a href="index.php/weekly-specials">Weekly Specials</a> | <a href="index.php/contact-us">Contact</a><br />
        Copyright &copy; 2009 Hoosick Street Beverage Center. All rights reserved. Powered by <a href="http://wordpress.org/" target="new">WordPress</a>

    </div><!-- end footer -->
What I would like to do is add something like "Valid XHTML and CSS.", after the "WordPress" link and have "XHTML" be a link to the XHTML validator page and "CSS" be a link to the CSS validator page. The CSS link will stay the same but the XHTML link will be different from page to page (obviously). This is where I am stuck. I am very new to php so any help is much appreciated.
