How is it used for a website then?
Some program is using the ID 4 and the value of "cus" to bring up
information you requested on a prior page. Probably to query a database
for those values.
As Ashley said: it is GET ($_GET) data in a URL -- a way to pass values
from one page to another using the URL.
Look up $_GET or Predefined Variables in the PHP documentation online.
If that doesn't help, you need to buy the most basic book on web
programming you can find (and read it).
