DOMDocument
If you get the error message "domdocument::domdocument() expects parameter 2 to be long, string given" for a code sample like this:
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->xmlStandalone = false;
echo $dom->saveXML();
which is obviously correct if you compare the constructor signature:
__construct ([ string $version [, string $encoding ]] )
make sure you're not overwritting this dom library by another (f.e. extension=php_domxml.dll in php.ini). XAMPP f.e. delivers its standard version with php_domxml.dll which ends up in this error message
DOMDocument::__construct

Not sure if this is what you meant when you said "The constructor example clearly shows that version and encoding only end up in the XML header", but you can also affect other parameters in the generated XML header, by accessing the DOMDocument's properties, for example:
<?php
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->xmlStandalone = false;
echo $dom->saveXML();
// <?xml version="1.0" encoding="UTF-8" standalone="no"?>

Make sure that php_domxml.dll on windows is removed before using the domdocument class as they cannot coexist.

Be aware using the encoding parameter in the constructor.
It does not mean that all data is automatically encoded for you in the supplied encoding. You need to do that yourself once you choose an encoding other than the default UTF-8. See the note on DOM Functions on how to properly work with other encodings...
The constructor example clearly shows that version and encoding only end up in the XML header.
