The point is you can put raw HTML (or anything else!) in there which can be
extremely useful for very long chunks, or blocks containing lots of quotes.
I think that example could have been better constructed to illustrate this
point; something like:
function my_function ( )
{
echo "<p class=\"interesting\">\n"
echo " My <a href=\"function_source.php\">function</a> was
called\n"
echo "</p>\n";
}
<?php
function my_function ( )
{
?>
<p class="interesting">
My <a href="function_source.php">function</a> was called
</p>
<?php
}
?>

Yes.
