The XML declaration does not need to be handled specially.

You should output it via an echo statement, in case your code is ever used on a server that is (poorly) configured to use short open tags.

But there's no need to treat the ?> at the end of the string specially.  That's because it's in a string.  The only thing PHP ever looks for in a string is \ or $ (the latter only in double-quoted strings.)

I have never had need for the following, as some have suggested below:

<?php
$xml
=rawurldecode('%3C%3Fxml%20version%3D%221.0%22%3F%3E');
echo(
$xml);
?>

<?php echo '<?xml version="1.0" ?'.'>' ?>

<?php echo "<?xml version=\"1.0\"\x3F>" ?>
