### 更新日志

版本 | 说明
--- | ---
8.3.0 | Calling this method on a node without a parent is now a no-op to align the behaviour with the DOM specification. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.
8.3.0 | Calling this method on a node without an owner document now works. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.

### 示例

示例 #1 DOMElement::after() example

Adds nodes after the hello element.

    <?php
    $doc = new DOMDocument;
    $doc->loadXML("<hello/>");
    $container = $doc->documentElement;

    $container->after("beautiful", $doc->createElement("world"));

    echo $doc->saveXML();
    ?>

以上示例会输出：

    <?xml version="1.0"?>
    <hello/>
    beautiful
    <world/>
