How to add text node in new created element with PHP DOMDocument

Question

How can I add content to the newly created tag? For example, I need to create like the following tag:

<script src="https://stackoverflow.com/">
    alert("ok");
</script>

I have implemented the following code:

$finalDom = new DOMDocument;
$finalDom->loadHTML("", LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);


$newElement = $finalDom->createElement("script");
$newElement->setAttribute("src", "https://stackoverflow.com/");

$finalDom->appendChild($newElement);

The result of this code is an only empty script tag:

<script src="https://stackoverflow.com/"></script>

you can use createTextNode to add text node for the element, as

....
$newElement->setAttribute("src", "https://stackoverflow.com/");
$finalDom->appendChild($newElement);
$newElement->appendChild($finalDom->createTextNode('your text here'));
....

You can set the content using $textContent property of DOMElement.

$newElement = $finalDom->createElement("script");
$newElement->setAttribute("src", "https://stackoverflow.com/");

$newElement->textContent = 'alert("ok");';

You can use any of these three options for adding text

elem.append(document.createTextNode(text))
elem.innerHTML = text
elem.textContent = text
