I come from a scripting background so am not unfamiliar
with the concept of CR/LF characters. I am in the process
of learning PHP via the following tutorial
http://mobilitystudies.com/mob/images/stories/PHP_Tutorial_From_beginner_to _master.pdf
Currently I have "hello.php" with the following lines of code
-------------------------
<html>
<body>
<?php
$d=date("D");
if ($d=="Fri")
echo "Have a nice weekend!";
elseif ($d=="Sun")
echo "Have a nice Sunday!";
else echo "Have a nice day!";
echo "\nhello boss"."\t"."does this work".PHP_EOL;
echo "again";
?>
</body>
</html>
---------------------------------
When I load this in my browser I see the following
------------------------
Have a nice Sunday! hello boss does this work again
-------------------------
And if I look at the page source (using Firefox)
--------------------------
<html>
<body>
Have a nice Sunday!
hello boss does this work
again</body>
</html>
------------------------
Should the "\n" not push a NewLine out to the output?
I did some research and found that the PHP_EOL seems to be what is
recommended since it is platform independant. But it doesn't work
either.
Can anyone suggest or point out what I am doing wrong, or is this a flaw
in php?
Thanks

I would use:
echo "<br />";
Which will force a line break in HTML.

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.

or we could use a <p> to force a paragraph switch.

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 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.

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.

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.

W3Schools can be safely and must be strongly recommended against for use as
a reliable resource on Web development. When in doubt, consult the official
Specifications:
<http://www.w3.org/TR/html401/struct/text.html#edef-P>
However, the P/p element does have an _end_ tag, and it is a good idea to
use it so that the paragraph will be delimited *explicitly*. In XHTML, it
is mandatory anyway, as XHTML is an application of XML and well-formedness
requires either an end tag or SHORTTAG syntax (as below).
> That would be an advantage of using <br /> for the OP.
<br /> is XHTML SHORTTAG (not considering HTML SHORTTAG, which is widely
disregarded by browsers); <br>, <bR>, <Br> or <BR> is HTML. PHP has the
nl2br() function to make printing newlines as BR/br elements in (X)HTML
easier.
BR/br usually suffices for debugging purposes. However, semantics are
important: If the intention is to make a paragraph, use the P/p element; if
it is to make an unconditional *line break* *within* *a* *text* *paragraph*,
use the BR/br element.

There seems to be confusion about whether or not the / is optional. In
reality, of course, all browsers honour it.

Whether browsers honor it or not is immaterial. It is directly against
the HTML spec, and attempts to validate pages with such ops will fail.
Just because browsers currently support it does not mean future browsers
will support something that violates the spec. It's also very sloppy
programming.
You are much better off conforming to the spec so the browser doesn't
have to guess at what you want.
Additionally, <br> does not have the same effect as <p>...</p>.

Yes, that only *seems* to be so.
> In reality, of course, all browsers honour it.
Your logic is flawed. You simply cannot know about *all* browsers.
AISB, *some* browsers, perhaps the majority in terms of market share, do not
implement the SGML Declaration for HTML 4.01 [1] properly, which specifies
the SHORTTAG syntax for HTML so that `<br />' is equivalent to `<br>>' in
HTML (that allows, for example `<h1/My Title/' instead of `<h1>My
Title</h1>') [2]. But the W3C Validator [3] does, which is why, e. g.,
<link … rel="…" … />
is _not_ a Valid HTML 4.01 fragment (as `>' would be character data which
is not allowed within the `HEAD' element).
This has led to the *current* HTML5 Working Draft regarding the trailing `/'
between `<' and the corresponding `>' of a start tag as allowed and optional
in the HTML syntax of HTML5 [4,5]. But you SHOULD NOT rely on that
outside of HTML5, perhaps not even in HTML5 until it has become stable.

They would with a DOCTYPE like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Note: 'XHTML' above...
*XHTML* requires the </p> tag and <br /> and would raise at least a
warning if </p> were missing or there were br's with out the / (<br>).
Plain HTML4 does not need the </p> and should not support the <br />
tags (whether browsers browsers honor it or not).

What are you using for a doctype? Obviously not html.

Not needed, it's HTML5.

Ah, yes. The "floating standard". I'll start using it when they stop
changing the standards (and browsers have better support for it).

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

Then you've only been looking at rubbish source.
