    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.

    <?php
    $doc     = new DOMDocument;
    $doc->loadXML("<container><![CDATA[hello]]></container>");
    $cdata = $doc->documentElement->firstChild;

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