How do I Convert jSON to XML

Question

Before I begin, I know there are a bunch of questions similar to this, but trust me, I read all, if not most of them. I tried a bunch of solutions, but none of them seem to

I had problems with numeric tags using Ghost solution. I had to changed it a bit to remove the numeric tags (just adding a n before):

function array2xml($array, $xml = false){

   if($xml === false){
       $xml = new SimpleXMLElement('');
   }

   foreach($array as $key => $value){
       if(is_array($value)){
           array2xml($value, $xml->addChild(is_numeric((string) $key)?("n".$key):$key));
       } else {
           $xml->addChild(is_numeric((string) $key)?("n".$key):$key, $value);
       }
   }

   return $xml->asXML();
}

Anyways it does not use attributes, and it does not make arrays with numbers as nodes with same name. I have changed it a bit more to:

function array2xml($array, $parentkey="", $xml = false){

   if($xml === false){
       $xml = new SimpleXMLElement('');
   }

   foreach($array as $key => $value){
       if(is_array($value)){
           array2xml($value, is_numeric((string) $key)?("n".$key):$key, $xml->addChild(is_numeric((string) $key)?$parentkey:$key));
       } else {
           $xml->addAttribute(is_numeric((string) $key)?("n".$key):$key, $value);
       }
   }

   return $xml->asXML();
}

Changing the call to

$xml = array2xml($jSON, "", false);

With this you get a more natural xml output using attributes and having nodes with same name.
