PHP method to convert array to XML

The example in this article describes how to convert an array into XML in PHP. Share it with everyone for your reference. The details are as follows:

1. The php code is as follows:

<?php
class A2Xml {
  private $version  = &#39;1.0&#39;;
  private $encoding  = &#39;UTF-8&#39;;
  private $root    = &#39;root&#39;;
  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(
  &#39;hello&#39; => &#39;11212&#39;,
  &#39;world&#39; => &#39;232323&#39;,
  &#39;array&#39; => array(
    &#39;test&#39; => &#39;test&#39;,
    &#39;b&#39;  => array(&#39;c&#39;=>&#39;c&#39;, &#39;d&#39;=>&#39;d&#39;)
  ),
  &#39;a&#39; => &#39;haha&#39;
);
$xml = new A2Xml();
echo $xml->toXml($res);
