Question
question about <<<
This code:
$text = <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon no extra whitespace!
END;
echo $text;
print $text;
This appears to me in a single line. Shoudn't it appear in 4 different lines?
This has a broader question which is:
I have an textarea box ... I put the stuff in the Database(mysql) ... it has \n in the middle of the text ... how do I print back the results so that it retains the \n ?
I've been working with PHP for a few years now ... but this still eludes me ... (mainly because I really never needed it ... I always use <br>'s)

Answers
You are getting the "here document" (in short heredoc) staff a little wrong. You don't need ";" to end the heredoc statement, but rather to end the variable assignment statement. This little precisation allows you to play tricks like this:
$text = nl2br(<<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon no extra whitespace!
END
);

browsers don't look at \n as a new line, but simply as a character they don't have to display.
They only obey to <br /> to make a new line.
Your text example doesn't contain <br /> but \n, thus your browser doesn't show a new line.
either put in <br /> in the initial text or use the function nl2br($text); to convert "\n" to "<br />\n"
regarding your database, \n will also be stored in your database as any other character, so when you retrieve that you can work with \n. If you need to display it in a html page, then you can use nl2br() again to add <br />
If you remember that \n is only treated as a new line character in text-editors and text fields; and <br /> is for new lines in html then it should be fairly simple :)
note: <br /> is the XHTML version of <br> in older versions of HTML.
