                    [max_person] => 8
                    [max_bedrooms] => 4
                )

            [image] => uploads/123.jpg
            [price] => 1950

Try usort (http://php.net/manual/en/function.usort.php)

You should have something like:

function cmp($a, $b)
{
    if ($a['price'] == $b['price']) {
        return 0;
    }
    return ($a['price'] < $b['price']) ? -1 : 1;
}

usort($table, "cmp");
