Is there a way to chomp all whitespace both at the beginning and end of a string? I was thinking of using a regexp like s[^\s*?][]sg and s[\s*?$][]sg; Is there a better way? (I'm thinking of PHP's trim function)
I imagine so because I don't think your expressions trim anything. You made them non-greedy and gave them the option to match 0 spaces. Since that's pretty ungreedy, I'm betting they'll do just that. Also, there's no need form either modifer /s or /g.
sub trim { $_[0] =~ s/^\s*//; $_[0] =~ s/\s*$//; $_[0]; }

P.S. If it makes you feel any better, I don't think this is covered in Network Programming with Perl. ;)
