리턴 array An array of prefValue => array(content/types)

 /**
  * Determines which content-types the client prefers. If no parameters are given,
  * the single content-type that the client most likely prefers is returned. If $type is
  * an array, the first item in the array that the client accepts is returned.
  * Preference is determined primarily by the file extension parsed by the Router
  * if provided, and secondarily by the list of content-types provided in
  * HTTP_ACCEPT.
  *
  * @param string|array $type An optional array of 'friendly' content-type names, i.e.
  *   'html', 'xml', 'js', etc.
  * @return mixed If $type is null or not provided, the first content-type in the
  *    list, based on preference, is returned. If a single type is provided
  *    a boolean will be returned if that type is preferred.
  *    If an array of types are provided then the first preferred type is returned.
  *    If no type is provided the first preferred type is returned.
  * @see RequestHandlerComponent::setContent()
