xml version 1.0 encoding utf-8 in php?

Question

Hi, I am trying to show

xml version 1.0 encoding utf-8 in php, I have tried :

echo '<?xml version="1.0" encoding="utf-8"?>';

but this doesnt validate on w3c, when using it in xhtml, the php shows an error.

Whats the easiest way to fix this? With it validating

Thanks

error on w3c:

Line 5, Column 46: character "'" not allowed in prolog

echo '<?xml version="1.0" encoding="utf-8"?>';

Line 5, Column 45: XML Parsing Error: Start tag expected, '<' not found

echo '<?xml version="1.0" encoding="utf-8"?>';

php error:

Parse error: syntax error, unexpected T_STRING in /home/public_html//request.php on line 7

<?php 
session_start();
include ('../connection.php');
include ('../functions.php');
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
?>

Answer 1

Based on your error messages, sorry if this comes off condescending, but is your code wrapped in PHP opening and closing tags?

That is, does your file look like this?

<?php
echo '<?xml version="1.0" encoding="utf-8"?>';
?>

Or just this?

echo '<?xml version="1.0" encoding="utf-8"?>';

Answer 2

Did you include the <?php tag at the start of your script?

<?php
echo '<?xml version="1.0" encoding="utf-8"?>';
?>

Answer 3

the problem is short_open_tag = On in your php.ini
