Laravel / Eloquent WHERE NOT SUBQUERY

问题

I`m having trouble to setup a negative condition like such:

WHERE NOT( "last_day" "<=" $first_day OR "first_day" "<=" $last_day)

My query builder looks like this atm:

$query = $query->where(function ($query) use ($first_day, $last_day) {
   $query->where('last_day', '<=', $first_day);
   $query->orWhere('first_day', '<=', $last_day);
});

I would like it to be as such :

$query = $query->whereNot(function ($query) use ($first_day, $last_day) {
  $query->where('last_day', '<=', $first_day);
  $query->orWhere('first_day', '<=', $last_day);
});

To recap: I want an OR statement inside a negative WHERE condition. How can I accomplish this?

You can play with the logic

$query = $query->where(function ($query) use ($first_day, $last_day) {
   $query->where('last_day', '>', $first_day);
   $query->where('first_day', '>', $last_day);
});

Went with reverting constraints according to answer found here: Eloquent MYSQL statement : WHERE NOT(A OR B)

$query = $query->where('last_day', '>', $first_day)->where('first_day', '>', $last_day);
