The function XMLWriter::writeElement is used to write an element (i.e. a XML tag, an [optional] content, and a closing XML tag) in one line without sub-elements:

<?php

$oXMLout
= new XMLWriter();
$oXMLout->openMemory();
$oXMLout->writeElement("quantity", 8);
$oXMLout->writeElement("price_per_quantity", 110);
print
$oXMLout->outputMemory();

// produces:
// <quantity>8</quantity>
// <price_per_quantity>110</price_per_quantity>

?>

whereas if you want to include sub-elements you have to use the XMLWriter::startElement / XMLWriter::endElement pair:

<?php

$oXMLout
= new XMLWriter();
$oXMLout->openMemory();
$oXMLout->startElement("item");
$oXMLout->writeElement("quantity", 8);
$oXMLout->writeElement("price_per_quantity", 110);
$oXMLout->endElement();
print
$oXMLout->outputMemory();

// produces:
// <item>
// <quantity>8</quantity>
// <price_per_quantity>110</price_per_quantity>
// </item>

?>

Please note that XMLWriter::writeElement will automatically sanitize the content passed as second parameter, so & becomes &amp;, < becomes &lt; and so on.

If you want to input markup directly into an element without validating it, you should use XMLWriter::writeRaw, which writes the contents as is, without any sanitizing.

Note that if you write element names with spaces or another characters not permitted for W3C Recommendation (https://www.w3.org/TR/xml/#NT-NameStartChar) this method will throw: PHP Warning:  XMLWriter::writeElement(): Invalid Element Name
