What I would do in that case is define a variable or constant in your
top (index) page before including common.php, then check for it before
including signature.php. That way you aren't limited to only showing
it on index.php, but can instead pick and choose which pages to
include it on.

So, in your index.php (or any other page on which you want to show
the "signature") you would do something like this:

define('SHOW_SIGNATURE', true);
include('common.php');

Then, common.php might look something like this:

//output some HTML
if(defined('SHOW_SIGNATURE') && SHOW_SIGNATURE)
include('signature.php')
//output some more HTML

That's basically the same as checking the value of
$_SERVER['SCRIPT_NAME'] but it gives you a bit more flexibility.
