The Note You're Voting On

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

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