Some PHP functions that can accept DOMDocument or DOMElement as parameters include `DOMDocument::createElement()`, `DOMDocument::createTextNode()`, `DOMDocument::appendChild()`, `DOMElement::setAttribute()`, and `DOMElement::appendChild()`.

// Example code snippet demonstrating the use of DOMDocument and DOMElement in PHP functions

// Create a new DOMDocument
$dom = new DOMDocument();

// Create a new element
$element = $dom->createElement('div');

// Set an attribute for the element
$element->setAttribute('class', 'container');

// Create a text node
$textNode = $dom->createTextNode('Hello, World!');

// Append the text node to the element
$element->appendChild($textNode);

// Append the element to the document
$dom->appendChild($element);

// Output the XML
echo $dom->saveXML();
