\n doesn't work

I am writing a program, and I am using \n in double-quoted print statements,
which should give me a line break. It doesn't work. I'm running Apache 2.0
and PHP 5, with Mozilla Firefox as a browser. What is wrong?

And... you're not confusing \n <--> <br /> ?

Look at the source (view-source in your browser) or wrap the output in
<pre></pre> tags.

This one needs to go in the FAQ list.

\n gives you a newline break in the data sent to the browser, so if you
select the view source option in your browser you'll see the source
does indeed have a linebreak where you are expecting it. However,
linebreaks are ignored in HTML. To create a line break in HTML which is
rendered in the browser, you need the <br> tag.

Depends on what you want, it could be that you don't *want* the br element.

Heh - yes it's basic fundamental HTML skills we're talking about here.
Although I've seen this same question asked here a few times now...

Very true. I was making an assumption based on the same experience other
people have had when posting here about this problem. Plus it seems
very unlikely that print "\n" does not output a newline break ;)

Here's something that may help - especially if you have a bunch of
\n(s) in a database somewhere that you are generating dynamic pages
with (that you would like to see the line breaks in).

http://us2.php.net/nl2br

This little baby will insert a <BR> before any \n in whatever variable
or string you pass to it. I use this for pages where users get to type
info into a field and hit \n\n to create a new paragraph. When they
submit it to a database, it is raw, but when I pull it out, I pass it
through nl2br and it adds the <BR>(s) for me.

Not sure if that's what you are looking for, but it's worth saying just
in case.

It already is (kind of):

It DOES output a newline break. Do a View->Source to prove it.

The issue is that newlines in HTML are just plain old white space, and are
removed when the page is rendered.

To get a line break rendered, you need to output a <br> tag.

I know that, and that's exactly what I posted in my reply to the OP ;)

Depends :-D. In a <pre> it *does* count, and there are some other places
where it counts (sometimes in old browsers at unexpected places).
