Answer 3

You can use the standard php uasort function You
can read it here
php uasort
uasort($Array, function($first, $second) {
if ($first->p == $second->p) {
return 0;
}
return ($first->p < $second->p) ? 1 : -1;
});

Answer 4

Most likely there is no ready-made solution for such sorting, it is too specific. Create a separate array with element ID and property value... sort this array.
