首页 / 网页编程 / PHP / php实现将数组转换为XML的方法

本文实例讲述了php实现将数组转换为XML的方法。分享给大家供大家参考。具体如下:
1. php代码如下:

<?phpclass A2Xml {private $version= "1.0";private $encoding= "UTF-8";private $root= "root";private $xml= null;function __construct() {$this->xml = new XmlWriter();}function toXml($data, $eIsArray=FALSE) {if(!$eIsArray) {$this->xml->openMemory();$this->xml->startDocument($this->version, $this->encoding);$this->xml->startElement($this->root);}foreach($data as $key => $value){ if(is_array($value)){$this->xml->startElement($key);$this->toXml($value, TRUE);$this->xml->endElement();continue;}$this->xml->writeElement($key, $value);}if(!$eIsArray) {$this->xml->endElement();return $this->xml->outputMemory(true);}}}$res = array("hello" => "11212","world" => "232323","array" => array("test" => "test","b"=> array("c"=>"c", "d"=>"d")),"a" => "haha");$xml = new A2Xml();echo $xml->toXml($res);
2. 运行效果如下图所示:

希望本文所述对大家的php程序设计有所帮助。
