in reply to catching newlines from textarea input

You simply forgot to return $txt. A sub returns the result of the last statement by default, in your case this is the substitution. Try this instead:
#!/usr/local/bin/perl -w use strict; my $txt="This is a line\nThis is a line as well\n\nThis is the last li +ne\n"; print ubb_txt($txt); sub ubb_txt { my $txt = shift; return "" unless ( defined $txt); my ($nl)=$txt =~ m{(\cM?\cJ)}; $txt =~ s{$nl$nl}{</p><p>}gs if (defined $nl); $txt =~ s{$nl}{<br>}gs if (defined $nl); return $txt; } __END__ This is a line<br>This is a line as well</p><p>This is the last line<b +r>
Your sub was returning the number of substitutions made (i.e. the result of the last substitution).

    uups robartes you are right forgot to paste it in, because omited several lines of ubb_txt like $str =~ s//&Uuml;/igs;

      You may want to look at HTML::Entities instead of hand-rolling all your own entity encodings.
