What's wrong with just putting the url parameters in the link that you know
you need, one by one?

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>";

Also, don't just output the values sent to the server, as that's an attack waiting to happen.

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

I would add the parameter you want to $_GET ($_GET['lang']='en') and use http_build_query on $_GET if you really want to include the whole query string in the call:

echo '<a href="index.php?'.http_build_query($_GET).'">Flip</a>";
