Heredoc in PHP to reduce a lot of echo calls

Heredoc is a way of building strings for output. Funnily enough I found there was a mistake in some of the coding on the Wikipedia page, but I won't hold that against them. Also, in some of the examples I've come across on the web, they don't seem to recognise an important feature of heredoc. That is, it also provides HTML output.

Below is some example PHP code with the correct syntax, use of variables and HTML. That should speed things up a bit.

<?php
$recipient = 'Mick';
$sender = 'Johnnie';
$x = <<<EOF
Dear $recipient,
I wish you to leave Sunnydale and never return.<br />
Not Quite Love,
$sender
EOF;
echo $x;
?>
