Then you've only been looking at rubbish source.

No, its a flaw in your understanding of HTML which does not recognise 
white space including new lines.

use <BR> instead.

The fact that it looks OK in your page source indicates this isn't a PHP 
problem, but an HTML one.  HTML ignores most whitespace.

Before getting into PHP too much, I would suggest you get a book on HTML 
and learn more about how it works, or you'll continue to fight 
"problems" like this in the future.

A web browser considers new lines within the text content of html 
documents to be white space, just as it considers spaces and tabs within 
the text content of html documents to be white space.

Line breaks are signalled by "<br>" or "<br />" (which you use depends on 
the dtd you declare, if you don't declare a dtd use <br>) and paragraphs 
are wrapped in "<p></p>". In html, these elements control forced line 
breaks.

Carriage returns in the text content of html documents don't generate 
line breaks.

If you're using a scripting language such as php to generate 
presentational markup such as html, you need to make sure you understand 
what correct presentational markup looks like first.

Well, to be REALLY pedantic, the <p> marker doesn't force a line break.
It does whatever the paragraph break is supposed to do, whether that's
vertical boundry space, boundry with indent, indent alone, outdent,
continuous with pilcrow, etc. It's all dependant on what the browser is
set up to support, what styles are in effect, whether they're from the
site or overridden by the user, etc. HTML is not layout.

As was to be expected on a Sunday.

Well it does, doesn't it? Without the "\n" and the PHP_EOL your source 
would look like this:

 > Have a nice Sunday!hello boss	does this workagain

The output of PHP is the HTML source code. How the browser renders that 
is another matter. If you want the line breaks to appear in the 
browser's output, do as the other posts suggest.

Greetings,

A newline in output interpreted as HTML is rendered no differently
from a space or series of spaces.  It shows up as a newline in "view
source" of browsers but not in rendered HTML.

If you want to cause a line break, do it in HTML.  <br> and <p> are
commonly used for this.  Also, there's <tr> inside tables, which
does a bit more than just a line break.

If you output your text with header("Content-Type: text/plain")
(read the documentation about how to use this:  HTTP headers have
to come *before* any text sent to the browser.  Even a single space
or newline.) or otherwise get the web server to call it a plain
text file rather than HTML, newlines will be visible.

Simple Answer:
\n is PHP for breaking a line. It is not translated as the HTML <BR>
as you (and I when I first started using PHP) had been expecting. It
will format your HTML source with new lines - without it all the
source would run together on one line.

To have the browser break a line you need to still each to the browser
an HTML line break <BR>.

So examples:
code:
echo "1, 2, 3, 4, \n5, 6, 7";

output:
1, 2, 3, 4, 5, 6, 7

source view:
1, 2, 3, 4, 
5, 6, 7

--------------------------------------------
code:
echo "1, 2, 3, 4, \n<BR>5, 6, 7";

output:
1, 2, 3, 4, 
5, 6, 7

source view:
1, 2, 3, 4, 
<BR>5, 6, 7
--------------------------------------------

code:
echo "1, 2, 3, 4, \n<BR>\n5, 6, 7";

output:
1, 2, 3, 4, 
5, 6, 7

source view:
1, 2, 3, 4, 
<BR>
5, 6, 7

Hope that makes it simple and clear.
Mike
