How to use PHP DOM functions to create XML

Do you need to create XML using PHP? Then you can use the PHP DOM functions to create an XML file. If you have worked with PHP 4 earlier then there is a slight change in the syntax of PHP 5. It is easy to work with this syntax if you have already worked with the browser's DOM functions.

The new DomDocument() function is used to create a new DOM Document object. After creating the new document object, you can add elements to it using the document object's createElement() method.

Using this method you can create the different elements that are needed for the document. Suppose you want to add a text content to the particular node you can use the createTextNode() method to create the text node and then use appendChild() method to append that text node to any element of your choice.

Then append that element to the root node of the XML document using the same appendchild() method. Now you can save the XML to another file also or print it out in the browser.
