Answer 1

Try:

$xmlString = $doc->saveXML();
$xmlString = str_replace("<?xml version=\"1.0\"?>\n", '', $xmlString);
file_put_contents($filename, $xmlString);

Answer 2

XML header tags and PHP short tags are incompatible. So, this may be an issue of using the short tags in PHP (i.e. <?= instead of <?php echo...). So, turning off short tags in PHP.INI (and updating your code appropriately) may resolve this issue.

I have a simmilar solution to the accepted answer:

If you have xml allready loaded in a variable:

$t_xml = new DOMDocument();
$t_xml->loadXML($xml_as_string);
$xml_out = $t_xml->saveXML($t_xml->documentElement);

For XML file from disk:

$t_xml = new DOMDocument();
$t_xml->load($file_path_to_xml);
$xml_out = $t_xml->saveXML($t_xml->documentElement);

Answer 4

There's another way without the replacing xml header. I prefer this:

$xml = new xmlWriter();
$xml->openMemory();
$xml->startElement('abc');
$xml->writeAttribute('id', 332);
$xml->startElement('params');
$xml->startElement('param');
$xml->writeAttribute('name', 'aa');
$xml->text('33');
$xml->endElement();
$xml->endElement();
echo $xml->outputMemory(true);

Gives output:

<abc id="332"><params><param name="aa">33</param></params></abc>
