### Description The following code: ```php <?xml version="1.0" encoding="UTF-8"?> <note> <to><?php echo "Is this valid PHP"; ?></to> <body>This is valid XML</body> </note> ``` Resulted in this output: ``` Parse error: syntax error, unexpected identifier "version" in /home/user/scripts/code.php on line 1 ``` But I expected this output instead: ```XML <?xml version="1.0" encoding="UTF-8"?> <note> <to>Is this valid PHP</to> <body>This is valid XML</body> </note> ``` Why should I have an echo? ```php <?php echo '<?xml version="1.0" encoding="UTF-8"?>'; <note> ... </note> ``` ### PHP Version PHP 8.0.30 ### Operating System _No response_
