in thread Creating a regex to match part of a URL's domain name (was: pattern matching)

hmm i used part of your code in a subroutine, and it's giving me the error "Use of uninitialized value at ./index.cgi line 29."
here's the function:
sub getd {

my $string = @_;
my $wanted;
my $domain;

($domain) = split '/', $string;
$wanted = (split /\./, $domain)[-2];

return $wanted;
}

my $variable = "www.google.com";
print &getd($variable);   # this is line 29.

    You're not doing any rudimentary data-checking, or you'd see that my $string = @_ was assigning a number to your variable. 
    # try one of these:

my ($string) = @_;
my $string = shift;
my $string = $_[0];

      my $variable = "http://www.google.com"; ? does this subroutine not handle "/"'s?

        ok, now that i've embarrassed myself.. (:
        i figured a way around it; i just simply left out http:// and placed it statically in another portion of the code; i can always make a workaround if i need to link to, say, something with an ftp:// protocol heading. (:
        sorry for all the mess and frustration (although most of it was likely on my part hehe)
        thanks!
