Returning a matching key(different value) from an 2 associative arrays,

So lets say we have two arrays as such : 

$x = array(
   "id" => 12,
   "name" => "Joe",
   "surname" => "Murphy",
   "age" => 52
);

$y = array(
   "id" => 12,
   "name" => "Joe",
   "surname" => "Murphy",
   "age" => 53
);

function key_compare_func($key1, $key2)
{
    if ($key1 == $key2)
        return 0;
    else if ($key1 > $key2)
        return 1;
    else
        return -1;
}

var_dump(array_intersect_ukey($x, $y, 'key_compare_func'));

This would return all matching elements from $x

array(4) { 
["id"]=> int(12) 
["name"]=> string(3) "Joe" 
["surname"]=> string(6) "Murphy" 
["age"]=> int(52) 
}

I need to get only ["age"]=> int(52)

I looked at these, but none seem to offer this sort of functionality, unless I missed something :

array_​udiff_​assoc, array_​uintersect_​assoc, array_​uintersect_​uassoc,
array_​udiffarray_​uintersect, array_​udiff_​uassoc
