I'm working from a question I posted earlier (here), and trying to convert the answer to a sub so I can use it multiple times. Not sure that it's done right though. Can anyone provide a better or cleaner sub?

sub search_for_key
{
    my ($args) = @_;

    foreach $row(@{$args->{search_ary}}){
        print "@$row[0] : @$row[1]\n";
    }

    my $thiskey = NULL;

    my @result = map { $args->{search_ary}[$_][0] }     # Get the 0th column...
        grep { @$args->{search_in} =~ /$args->{search_ary}[$_][1]/ } # ... of rows where the
            0 .. $#array;                               #     first row matches
        $thiskey = @result;

    print "\nReturning: " . $thiskey . "\n";
    return $thiskey;    
}

search_for_key({
    'search_ary' => $ref_cam_make, 
    'search_in' => 'Canon EOS Rebel XSi'
});
