Regex - validate URL?

    Regex is definitely not my strong front and I am trying to validate that the input is a valid URL. A search on google yields tons of variations, all of which seem to be very basic and fail a valid url quite easily.

    Does anyone have a reliable pattern to validate a url?

    Appreciate it!

    $urlpattern = "((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)";

    That seems to validate
    - no domain extension?

    Edit: nevermind, I guess that is a valid url...
