Array to XML in PHP

Do you need to convert an array to XML?

We do not have something to do it directly as we will do with json_encode. But with a small search you can find few solutions.

Have tried different ones, this one seems the one that works the best and quite elegant still.

/**
* Converts an array to XML
*
* @param array $array
* @param SimpleXMLElement $xml
* @param string $child_name
*
* @return SimpleXMLElement $xml
*/
public function arrayToXML($array, SimpleXMLElement $xml, $child_name)
{
    foreach ($array as $k => $v) {
        if(is_array($v)) {
            (is_int($k)) ? $this->arrayToXML($v, $xml->addChild($child_name), $v) : $this->arrayToXML($v, $xml->addChild(strtolower($k)), $child_name);
        } else {
            (is_int($k)) ? $xml->addChild($child_name, $v) : $xml->addChild(strtolower($k), $v);
        }
    }

    return $xml->asXML();
}

$this->arrayToXML($array, new SimpleXMLElement(''), 'child_name_to_replace_numeric_integers');

I got it from stackoverflow where you can check other solutions.
