我们知道php中的simpleXML没办法直接很方便的添加CDATA格式的数据,这样对我们操作时会有一定的问题,下面我来给各位同学介绍php simpleXML添加CDATA格式数据一种办法,php实例代码如下:

<?php

/**

* to show <title lang="en"><![CDATA[Site Title]]></title>   instead of <title lang="en">Site Title</title>

*

*/

class SimpleXMLExtended extends SimpleXMLElement

  {

  public function addCData($cdata_text)

    {

    $node = dom_import_simplexml($this);

    $no   = $node->ownerDocument;

    $node->appendChild($no->createCDATASection($cdata_text));

    }

  }//开源代码Vevb.com

$xmlFile    = 'config.xml';

// instead of $xml = new SimpleXMLElement('<sites/>');

$xml = new SimpleXMLExtended('<sites/>');

$site = $xml->addChild('site');

// instead of $site->addChild('site', 'Site Title');

$site->title = NULL; // VERY IMPORTANT! We need a node where to append

$site->title->addCData('Site Title');

$site->title->addAttribute('lang', 'en');

$xml->asXML($xmlFile);

?>
