Answer 1

Here is my entry, simple and clean..

function array2xml($array, $xml = false){
    if($xml === false){
        $xml = new SimpleXMLElement('');
    }
    foreach($array as $key => $value){
        if(is_array($value)){
            array2xml($value, $xml->addChild($key));
        }else{
            $xml->addChild($key, $value);
        }
    }
    return $xml->asXML();
}


header('Content-type: text/xml');
print array2xml($array);
