to delete the trailing newline

[Stéphane JEAN BAPTISTE]

I have a variable and I want to write it into a textarea (HTML). The
problem is when I look at the textarea in my HTML page, there is the
text I want, plus a trailing newline.

How can I delete this.

My variable:
$texte=wazaa;

In textarea:
wazza


tks

Sorry for my english

You can chomp off that trailing newline using 'chomp'.  Weren't you the
guy who was asking about it yesterday?

This fortune intentionally says nothing.

you might want to try to use 'chomp' on your variable... this function
is specifically there to 'chomp off' trailing newlines

you'll often see it used as:

open FH, 'foo.txt';
while(FH){
chomp; #remove trailing newline
do something
}

perldoc -f chomp for details

Yes! But chomp delete it in perl but not the conversion in HTML.

Oh, I'm sorry!  Perhaps you have a newline embedded in your script, like
this:

textarea$variable
/textarea
