    (PHP 5, PHP 7)

    Creates a new DOMAttr object

    说明

    publicDOMAttr::__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.

    范例

    Example #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(); 
    ?>
    

    以上例程会输出:

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