DOMAttr::__construct

(PHP 5, PHP 7, PHP 8)

DOMAttr::__construct — Creates a new DOMAttr object

说明

public DOMAttr::__construct(string $name, string $value = "")

Creates a new DOMAttr 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 writable node, use DOMDocument::createAttribute.

参数

name: The tag name of the attribute.
value: The value of the attribute.

示例

示例 #1 Creating a new DOMAttr object

<?php

$dom = new DOMDocument('1.0', 'iso-8859-1');
$element = $dom->appendChild(new DOMElement('root'));
$attr = $element->setAttributeNode(new DOMAttr('attr', 'attrvalue'));
echo $dom->saveXML(); 

?>

以上示例会输出：

 
<?xml version="1.0" encoding="utf-8"?>
<root attr="attrvalue" />
