Variable in query

https://laravel.com/docs/5.8/queries#where-clauses

$users = DB::table('users')
                    ->whereIn('id', [1, 2, 3])
                    ->get();

You can use Named bindings as well

$results = DB::select('select * from users where id = :id', ['id' => 1]);

taken from laravel docs

I want to use variable $number in query like DB::select (..... whereIn ("id", $number ) ..... )

DB::select (..... whereIn ("id", $your_array ) ..... )
