Question

CGI / Perl remove new line character when printing to file.

Asked by: Sparky-Plug

I have an HTML textarea box that I want to save the input from into a text file.

Instead of printing each 'Enter /return' on a new line I want it on the same line with <br> printed instead.

I am using this at the moment but it doesn't quite work how I'd like;

$input =~ s/\n/<br>/g;

Example:
Input:

This
is

input.

Currently saves as:
This
<br>is
<br>
<br>input.

But I want it like this:

This<br>is<br><br>input.



If you get what I mean, is this possible?

Many Thanks, S-P.

Many Thanks, Both work equally well. Points will be halved between you.

Incidentally, what is the difference between New Line and Carriage Return?


Thanks again, S-P.

read verbatim :-)

carraige return \r means 'go back to the beginning of the line'
newline \n means 'go to a newline'
