char server[] = "192.168.0.2/TA/user_room.php"; // name address for Google (using DNS)
Does that completely useless, incorrect comment really serve any purpose?
client.println("GET /search?q=arduino HTTP/1.1");
After connecting to some bogus server (or trying to, anyway), does this GET request really make sense? It's fine if you are talking to google. It's useless when you try to talk to some other server.
