You need array_udiff:

$first = array(52=>array(10,24),55=>array(5,25));
$two = array(52=>array(10,24),55=>array(10,25));

function compare_func($a, $b)
{
    if ($a === $b) {
        return 0;
    }
    return ($a > $b)? 1:-1;
}
$diff = array_udiff($first, $two, 'compare_func');

print_r(array_keys($diff));


Array
(
    [0] => 55
)
