i an trying to build a url like

$valid-url = "p1=".rawurlencode($_GET['p1'])."&type=".rawurlencode($_GET['type'])."&os=".rawurlencode($_GET['os'])."&price=".rawurlencode($_GET['price'])."&sort=".rawurlencode($_GET['sort'])."&sort_order=".rawurlencode($_GET['sort_order'])."&perpage=".rawurlencode($perpage)."";

and then pass it to

<a href=

Ironically, $valid-url is not a valid variable name. No hyphens.
