چطور با استفاده از دستورات تو در توی where در لاراول و استفاده از clouser نتایج دقیق‌تری بگیریم؟

Reserve::select('id', 'from', 'till', 'room_number')
            ->where('room_number', $request->room_number)
            ->where(function ($query) {
                $query->whereBetween('from', $start, $end])
                    ->orWhereBetween('till', $start, $end);
            })
            ->get();

Reserve::select('id', 'from', 'till', 'room_number')
            ->where('room_number', $request->room_number)
            ->where(function ($query) use ($request) {
                $query->whereBetween('from', [$request->from, $request->till])
                    ->orWhereBetween('till', [$request->from, $request->till]);
            })
            ->get();

$exists = Reserve::where('room_number', $request->room_number)
->where(function ($query) use ($from, $till) {
	$query->whereBetween('from', [$from, $till])
	->orWhereBetween('till', [$from, $till]);
})
->count();
