When the link to the PHP script is called from a page which itself is called
with a query string and the link is clicked, the $_SERVER['HTTP_REFERER']
variable will contain the full URL, including the query string of the
originating page.
However, this is not the query string sent to the PHP script. So, when the
page containing the link is called with http://domain/?a=b and the link is
clicked sending the query string "foo=bar", the called PHP script will
receive http://domain/?a=b as the referrer (stored in the
$_SERVER['HTTP_REFERER'] variable) and the query string "foo=bar" will be
stored in $_GET, $_REQUEST or $_SERVER['QUERY_STRING'] as usual.
