Line Break Fails

[unemployment]

Why won't these break to a new line?

 

echo "{$c['blue']}" . "\n";
echo $c['green'] . "\n";

It does. The problem is web browsers ignores the new line characters (\n). You need to use the <br /> html tag in order for the browser to display text on a  new line.

 

PHP has a function for converting new line characters to <br /> tags called nl2br

oh ok... so what is the point of using \n or \r?

Any time you want a true linebreak, and not an HTML linebreak

Yes, such as when you view source, output in a shell, output inside HTML pre tags, in a textarea, etc.

So it seems like this is more for just making your code look nice.

PHP isn't just for HTML.

 

You use line breaks in text files, for example. PHP can generate text files.

they are also used for plain text as xyph said...like with the mail() function

Oh right.  I have used this before in my mail functions it's just been a while since i've written one.
