Current on a one file edit system

I am trying to setup my site so that when I edit one file it edi开发者_StackOverflow中文版ts all the header or footer. but with the header I there is a current, can someone give me a script so that it will add:<li id="current" class="grey active item1"> infront of the "<a href" and if it isnt currently "active" it will add: <li class="grey item26"> infront of the "<a href", would prefer this in PHP but javascript would be fine aswell.

Sources for you to look at if you need any more info:

www.isgclan.com

www.isgclan.com/test.php

www.isgclan.com/template/main/header.php

The file that starts all this is just:

<?php
    session_start();
    require('template/main/header.php');
    require("template/partnerscontent.php");
    require("template/main/footer.php");
?>

This sounds like it is a active menu item related question...

When you include/require files they inherit the scope of where they were called from. See Variable scope.

So from test.php you could set a variable

$active = 'test';

And then in the header.php file you can check that variable

<li <?php 
if ($active == 'test') 
    echo 'id = "current" class="grey active item1"';
else
    echo 'class=""grey item26"' 
?>> 

Then in other files you can set $active to something else and have that handle this.
