//      Usage:
//              $anons = array(
//                      array("ip" => "1.2.3.4", "port" => 8080, "type" => "socks4"),
//                      array("ip" => "1.2.3.5", "port" => 8080, "type" => "socks5"),
//                      array("ip" => "1.2.3.6", "port" => 8080, "type" => "proxy")
//              );
//
//              $pa = new phpanon(array("anons" => $anons));
//              $pa->check();
//              $pa->done();
//
//              $anons is an array of triples ("ip" => ip, "port" => port, "type" => type)
//                      ip: ip address of the socks / proxy
//                      port: port of the socks / proxy
//                      type: socks5 (for socks5), socks4 (for socks4), proxy (for proxy)
//
//              Other options:
//                      "url" => "http://www.example.com" : connection test page
//                      "needle" => "someword" : some word contained in the page set by "url"
//                      "user_agent" => "Mozilla Firefox" : set an alternative user_agent
//                      "url_referer" => "http://www.mypage.com" : set a referer url
