Access variable from other function LARAVEL -

i'm trying use returned result function function. here first function:

public function availablerooms(){     if(isset($_post['selecteddate'])){         $checkindatereceived = str_replace('/', '-', $_post['selecteddate']);         $checkindate = date('y-m-d', strtotime($checkindatereceived));         $availablerooms = db::table('rooms')             ->leftjoin('reservations', function ($secondjoin) use($checkindate) {                 $secondjoin->where('reservations.checkout_date', '<', $checkindate);             })             ->leftjoin('reservation_room_rel', function ($firstjoin) {                 $firstjoin                     ->on('reservation_room_rel.room_id', '=', 'rooms.id')                     ->on('reservation_room_rel.reservation_id', '=', 'reservations.id');             })             ->where([                 ['rooms.status', '=', 1]             ])             ->wherenull('reservation_room_rel.room_id')             ->get();         return $availablerooms;     } } 

and here second function:

public function returnaddreservation(){     $availableroomsret = $this->availablerooms();     $mealsupplement = new meal;     $accommodationsupplement = new accommodationsupplement;      $accommodationsupplements = $accommodationsupplement::where('status', 1)         ->orderby('name', 'asc')         ->get();     $mealsupplements = $mealsupplement::where('status', 1)         ->orderby('name', 'asc')         ->get();     return view('addreservation', [         'availablerooms' => $availableroomsret,         'accommodationsupplements' => $accommodationsupplements,         'mealsupplements' => $mealsupplements     ]); } 

first function returns correct result if runs independently, but, when dd($availableroomsret)it returns null. idea how access $availablerooms public function availablerooms() public function returnaddreservation() ? thanks!

as long in same class should value nothing related laravel pure php.

you can try doing so

public function availablerooms(){     $availablerooms = 15;     return $availablerooms; }  public function returnaddreservation(){     var_dump('inside class'. $this->availablerooms());     $availableroomsret = $this->availablerooms();     return $availableroomsret; }  public function thirdfunction(){     var_dump('inside third function' . $this->returnaddreservation()); }
