Description:
------------
phpinfo function generates invalid code. It tries to look like XHTML, but it has:
'<html>' instead of '<html xmlns="http://www.w3.org/1999/xhtml">',
'<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />' instead of '<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=&quot;utf-8&quot;"/>', the DTD declaration id invalid, it should be:
'<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">' if you stick at using XHTML 1.0 Transitional, it would be better if you use:
'<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">'. In addition there is no XML declaration. It should be:
'<?xml version="1.0" encoding="utf-8" standalone="no"?>' at the very beginning of the document and '<br />' should be replaced with: '<br/>'. I know that the code is valid due to W3C Validator, but when I use the function phpinfo(); I get plain text. When I add header('Content-Type: application/xhtml+xml; charset="utf-8"');, I receive XML without xmlns, so it still looks like plain text.

Reproduce code:
---------------
<?php
 phpinfo();
?>

Expected result:
----------------
The same as I receive by using:
<?php
 header('Content-Type: application/xhtml+xml;lcharset="utf-8"');
 ob_start();
 phpinfo();
 $dom = new DOMDocument('1.0', 'utf-8');
 @$dom->loadXML(ob_get_clean());
 $dom->documentElement->xmlNamespace = 'http://www.w3.org/1999/xhtml';
 print($dom->saveXML());
?>
and of course with corrections for:
'<meta/>', '<br/>'.

Actual result:
--------------
plain text. Just the source.
