写一个 PhalApi 处理XML

<?php

class XmlService {

/**
* 将数组转换为XML字符串
*
* @param array $data 数组数据
*
* @return string XML字符串

//使用示例
$xmlService = new XmlService();

//将数组转换为XML字符串
$data = array(

'age' => 18,

$xml = $xmlService->arrayToXml($data);
echo $xml;

//将XML字符串转换为数组
$xml = '<root><name>张三</name><age>18</age><hobbies><hobby>reading</hobby><hobby>music</hobby><hobby>sports</hobby></hobbies></root>';
$data = $xmlService->xmlToArray($xml);
print_r($data);
