I have a footer that I include on every page and would like it to
adapt to whatever situation it finds itself in.  Is your suggestion,
to do the following for the existing example:

echo "<a 
href='index.php?name=".$_GET['name']."&this=".$_GET['this']."&lang=en'>Flip</a>";

Are you referring to echoing the SCRIPT_NAME and QUERY STRING values
into the href attribute?
