\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 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.

It doesn't seem possible. But would the following also seem a violation of the general notions behind css? You have a DIV, say asociated with class, 'topdiv'. Inside of that you have an anchor (and whatever it contains), associated with class, 'a'. Somewhere else in, 'topdiv', there is a span or element (containing whatever), associated with class, 'b'.

Hello, In an ASPX page I have a "Quit" button which make a simple redirect in code-behind. This button doesn't work no more since (I think) I moved from the framework 1.0 to 1.1 and it doesn't work only on IE! My ASPX page works in FireFox. If the button doesn't work it's because of validators (and it worked with the same code in v1.0).
