When creating elements with DOMDocument, which method is used to create a new element?

• A. createElementNS
• B. newElement
• C. createElement
• D. createNewElement

Answer: (C)

The method used to create a new element in DOMDocument is indeed createElement. This method is part of the DOM extension in PHP, which provides a way to work with XML documents. When you want to add a new element to a DOM tree, you call createElement and pass the name of the element you want to create. For example, if you want to create a new element called "item", you would use `createElement('item')`. This will return a new DOMElement object representing the newly created element, which can then be appended to a parent element or otherwise manipulated. The other methods mentioned do not exist or serve different purposes. For instance, createElementNS is used to create elements with a namespace, which is a specific case involving XML documents requiring namespaces. The method newElement and createNewElement do not exist within the DOMDocument class, making them invalid choices.
