change css through php if ?

joural

hi all here is my tiny problem...
this my menu:

<li><a href="#home" class="selected">Home</a></li>
<li><a href="#pfrs">Problems in finding <br>the ideal 
                            school</a></li>
<li><a href="#fis">Finding the ideal school</a></li>
<li><a href="#about">My journey</a></li><br>
<li><a href="#studies">Case studies</a></li>
<li><a href="#endorsements">Endorsements</a></li>
<li><a href="#sts">Services to schools</a></li>
<li><a href="#links">Links</a></li>
<li><a href="#news1">Geoff Link in the news</a></li>
<li><a href="#contactus" class="last">Contact</a></li>
</ul>

and so my intention is that when certain link is clicked, for example links = "#links" so the css's will change otherwise it stays the same... so i thought i'll be able to solve it with this, just to find out it isnt working...

<?php if ($_GET['page'] >= fis) { ?>
<link href="template.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="css/layout2.css" type="text/css" charset="utf-8" />

<?php } else { ?>
<link href="template.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="css/layout.css" type="text/css" charset="utf-8" />
<?php } ?>

thank you all for any ideas

First off "fis" in the code above is a constant, which I'm rather certain you don't mean it to be. Did you intend to write $fis? You should turn on reporting of all errors, set log_errors to some file and for non-production environment, turning on display_errors is usually a good idea as well. This would tell you something along the lines of "Undefined constant fis". Moreover, undefined constants default to having the same value as the identifier, which in this case is the string literal "fis". There is no point in trying to make a >= comparison against a string.

Secondly, unless you actually intend to use an entirely different set of CSS rules, switching out the CSS file seems like overkill. If you merely wish to highlight the clicked link, you should instead add "selected" to its class names, and remove it from the previously selected link. Also note that a link with an href attribute of "#fragment_identifier" only scrolls the current document so that the element with the specified fragment_identifier comes into view. There will be no request to the server, and since there is no request to the server, no PHP code will be exeuted.
