Php的数组转换成XML(php Array to Xml)

前两篇文章说到WebService的问题，这个也是因为那个需求所以写的，接口返回XML给用户

php的数组转换到XML（注意php的版本）

<?php/***************************************************************** @ 2011 OsApi.Net Inc.* $author : LBC* $email : [e-mail]* $Id : toxml.php 2011/1/21*****************************************************************/class 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);

下面显示的结果：

<?xml version="1.0" encoding="UTF-8" ?> - <root> <hello>11212</hello> <world>232323</world> - <array> <test>test</test> - <b> <c>c</c> <d>d</d> </b> </array> <a>haha</a> </root>
