PHP - ArrayToXML Converter

arrayToXML.php

<?php
      
        function arrayToXML($array,$parent,$xml=null){
	
		$index = 0;

		if($xml == null){

			$xml = new SimpleXMLElement("<".$parent."/>");

			$child = $xml;

		}else{

			$child = $xml->addChild($parent);

		}

		if(gettype($array) == 'array'){

			reset($array);

			if(gettype(key($array)) == 'integer') unset($xml->$parent);

			foreach($array as $key=>$element){

				if(gettype($key) == 'integer'){

					$xml = arrayToXML($element,$parent,$xml);

				}else{

					$child = arrayToXML($element,$key,$child);

				}

			}

		}else{
		
			$index = ($xml->$parent->count())-1;

			$xml->$parent->$index = $array;

		}

		return $xml;

	}

?>

Improved Array To XML conversion function for PHP using SimpleXML and recursion.

First call can be both:

$xml = arrayToXML($array,"root"); 
// where "root" is the name of the root element in the XML you want to create

or

$xml = arrayToXML($array,"subroot",$superXml); 
// where $superXml is an XML DOM element where you want to add your XML as a child.

Update - Bug Fixing

The function now correctly generate "listed elements" i.e. list of xml elements with same tag name.
