If case really doesn't matter, then the best solution is to just initialize the values with lc.

However, you can also set the values to lc after the fact as well:

lcvalues(@array1);
lcvalues(@array2);

sub lcvalues {
    for (@_) {
        if (ref $_ eq 'HASH') {
            lcvalues(values %$_);
        } elsif (ref $_ eq 'ARRAY') {
            lcvalues(@$_);
        } elsif (ref $_) {
            warn "Unknown data type: " . ref $_;
        } else {
            $_ = lc $_;
        }
    }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
