Examples

Example 1. Creating a new DOMProcessingInstruction

<?php

$dom
= new DOMDocument('1.0', 'UTF-8');
$html = $dom->appendChild(new DOMElement('html'));
$body = $html->appendChild(new DOMElement('body'));
$pinode = new DOMProcessingInstruction('php', 'echo "Hello World"; ');
$body->appendChild($pinode);
echo
$dom->saveXML();

?>

The above example will output:

<?xml version="1.0" encoding="UTF-8"?>
<html><body><?php echo "Hello World"; ?></body></html>
