LaravelでのA and (B or C) の条件の作り方 where orWhere

◆A and (B or C) の条件の作り方

$datas = \User::where('created_at' ,'<>',null)
         ->where(function($query){
             $query->where('created_at','<',’2019-01-01’)->orWhere('update_at', '=', null);
         })->get();

$datas = \User::where('created_at' ,'<>',null)

->where(function($query){

$query->where('created_at','<',’2019-01-01’)->orWhere('update_at', '=', null);

})->get();

パラメータを渡したい時の例は以下

$date　= date('Y-m-d H:i:s',strtotime('-1 day'));
$datas = \User::where('created_at' ,'<>',null)
         ->where(function($query) use ($date){
             $query->where('created_at','<',$date)->orWhere('update_at', '=', null);
         })->get();

$date　= date('Y-m-d H:i:s',strtotime('-1 day'));

$datas = \User::where('created_at' ,'<>',null)

->where(function($query) use ($date){

$query->where('created_at','<',$date)->orWhere('update_at', '=', null);

})->get();
