This function can parse xml into an array, why?

<code>function xmlToArray($xml){     
    // 禁止引用外部xml实体    
    libxml_disable_entity_loader(true);    
    $xmlstring = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA);    
    $val = json_decode(json_encode($xmlstring), true);    
    return $val;    
} 
</code>

return $array_data;</code>
