Xml created in PHP node values and elements - php

Question

I do not understand these node value things at all i am trying to replicate an xml design in php but having quite a bit of trouble the file i am trying to reproduce through php is.
<items>
<item>
<id></id>
<name></name>
<price></price>
<quantity></quantity>
<description></description>
<qonhold></qonhold>
<qsold></qsold>
</item>
</items>
And the PHP file to recreate this is almost all done
$dom = new DOMDocument("1.0");
// create root element
$root = $dom->createElement("Items");
$dom->appendChild($root);
$dom->formatOutput=true;
// create child element
$item = $dom->createElement("item");
$dom->appendChild($item);
// create text node
$id = $dom->createElement("id");
$root->appendChild($id);
$name = $dom->createElement("name");
$root->appendChild($name);
$price = $dom->createElement("price");
$root->appendChild($price);
$quantity = $dom->createElement("quantity");
$root->appendChild($quantity);
$description = $dom->createElement("description");
$root->appendChild($description);
$qonhold = $dom->createElement("qonhold");
$root->appendChild($qonhold);
$qsold = $dom->createElement("qsold");
$root->appendChild($qsold);
The problem i am having is its saving it all under "items" being the root.. but i can not get everything id, name, price, quantity, description, qonhold, qsold to save under just "item" which is saved under "items

You should use ->appendChild() on the item node created, not the root which is <items>:
// create child element
$item = $dom->createElement("item");
$dom->appendChild($item);
// create text node
$id = $dom->createElement("id");
$item->appendChild($id); // item->appendChild not $root->appendChild
Should look like this:
$dom = new DOMDocument("1.0");
// create root element
$root = $dom->createElement("Items");
$dom->appendChild($root);
$dom->formatOutput=true;
// create child element
$item = $dom->createElement("item");
$root->appendChild($item); // append to `<Items>`
// create text node
$id = $dom->createElement("id");
$item->appendChild($id); // append to `<item>`
$name = $dom->createElement("name");
$item->appendChild($name); // append to `<item>`
$price = $dom->createElement("price");
$item->appendChild($price); // append to `<item>`
$quantity = $dom->createElement("quantity");
$item->appendChild($quantity); // append to `<item>`
$description = $dom->createElement("description");
$item->appendChild($description); // append to `<item>`
$qonhold = $dom->createElement("qonhold");
$item->appendChild($qonhold); // append to `<item>`
$qsold = $dom->createElement("qsold");
$item->appendChild($qsold); // append to `<item>`
