//

//      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
