DOMProcessingInstruction->__construct() --  Creates a new DOMProcessingInstruction object

说明

class DOMProcessingInstruction {

__construct ( string name [, string value] )

}

Creates a new DOMProcessingInstruction object. This object is read only. It may be appended to a document, but additional nodes may not be appended to this node until the node is associated with a document. To create a writeable node, use DOMDocument->createProcessingInstruction().

参数

value

The value of the processing instruction.

例子 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();

?>

上例将输出:

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