Since I have learned the ways of CGI.pm, the world has been a better place. But there are still some servers I have to write scripts for that don't have any CPAN modules installed.

When this happens, I normally use the following subroutine:

sub parsedata {
    ($ENV{'REQUEST_METHOD'} eq "GET") ? $in = $ENV{'QUERY_STRING'} 
        : read(STDIN,$in,$ENV{'CONTENT_LENGTH'});

    @in = split(/&/,$in);

    foreach $i (0 .. $#in) {
        $in[$i] =~ s/\+/ /g;
        $in[$i] =~ s/%(..)/pack("c",hex($1))/ge;
        $in[$i] =~ s/\n/ /g;
        $in[$i] =~ s/\r/ /g;
        ($key, $val) = split(/=/,$in[$i],2);
        $in{$key} .= '\0' if (defined($in{$key}));
        $in{$key} .= $val;
    }
}

This then makes a variable $in{'foo'} for the HTML form element named foo.

Great.

But I've also started writing use strict in all my code, and it's not real clear to me how I can get my scoping correct using the above function.

Any ideas?
