How transform this array?

Question

Here is data

$array = array(
    'random' => 1,
    'pewpew' => 2,
    'temp' => 5,
    'xoxo' => 3,
    'qweqweqe' => 4,
);

$fields = array('random', 'xoxo', 'temp');

I need to get in result:

$result = array(
    'random' => 1,
    'xoxo' => 3,
    'temp' => 5,
);

I mean keys presence/order from $fields apply to $array.

The question is: Can I perform this transformation using only array_ functions? (I don't wanna use iteations) If yes: can you link me function that I need?

(sorry for spelling mistakes)

upd.

PHP 5.2

Answer 1

$result=array_intersect_key($array ,array_flip($fields) );

Answer 2

// little trick required here...
$fields = array('random' => 0, 'xoxo' => 0, 'temp' => 0);
$result = array_intersect_key($array,$fields);
