Wouldn't you be able to do something like $formdata{$j} =~ s/[\n\r]+//gs; ?
Am I correct that this would
- treat the entire string as one line for purposes of matching,
- perform a global replace on one or more of "\n" (new line, aka line feed) and/or "\r" (return, aka carriage return), and
- replace them with nothing,
thus effectively removing them (as desired)? (You could also replace with a single space or something else, if preferred.)
(The other solutions presented, however, may be more correct and/or efficient, however-this was just what I threw together while reading the post. I tried testing against files I generated with lines ending in "\n", "\r", "\r\n", and "\n\r", and it appeared to work, but YMMV.)
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
