Answer 1

You forget port number. This is full function code to receive current page URL.

function selfURL() {
  $s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
  $protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s;
  $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
  return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI'];
}
