Unless your URL is more complicated than your example, you shouldn't need to use urlencode() at all. You'd need to use it in a case where your string may contain characters that aren't valid in URLs like spaces and such: $baseurl = "http://www.somesearchsite.com/search=";; $searchfor = "Grace O'Mally"; $searchurl = $baseurl . urlencode($searchfor); Since you set your URL explicitly and it's not something entered by a user, you shouldn't need it. Try that and see if it fixes your other problem with double encoding.. or at least gives a better clue as to where it's coming from.
